r: Roger Blandford\, The Kavli Institute for Particle Astrophysics and Cos
mology (KIPAC)\, Stanford University\n\nRecent\, remarkable images made by
the EHT collaboration exhibit a ring of emission\, presumably orbiting a
six billion solar mass black hole. It is proposed that what is observed is
not a gas torus but an extensive “ ergomagnetosphere' that connects mecha
nically to a much larger ``ejection disk’’ and that the powerful jets and
the disk are mostly powered by black hole spin\, not accretion. Implicatio
ns for general active galactic nuclei and other sources of relativistic je

DESCRIPTION:Topic: Perks and Pitfalls of Pebble Accretion — Implications fo
r Planet Formation in the Inner and Outer Disk\n\nSpeaker: Mickey Rosentha
l\, University of California\, Santa Cruz\n\nMuch recent work on planet fo
rmation has focused on planetary growth through accretion of particles who
se aerodynamic properties make them marginally coupled to the local nebula
. Growth of planets through accretion of these “pebbles\,' often termed 'p
ebble accretion\,' has several notable features when contrasted with “trad
itional” growth that relies on purely gravitational interactions. In this
talk\, I will give an overview of pebble accretion and discuss why the the
ory has garnered so much interest\, and then go on to describe several nov
el and important features of growth by pebble accretion that have emerged
from my work. Firstly\, I demonstrate that growth by pebble accretion qual
itatively changes for core masses above a minimum mass scale\, above which
far more pebble sizes are able to be accreted\, and particles can be capt
ured on scales comparable to the planet's hill radius. This change in beha
vior implies that the early stages of planetary growth must be fueled by p
rocesses other than pebble accretion\, which can bring planets up to the m
inimum masses needed for pebble accretion to take hold. I then discuss the
semi-major axes where gas giant formation can occur if these early stages
are dominated by accretion of planetesimals. Finally\, I show that consid
eration of the smallest sizes of particles that can be captured by pebble
accretion leads naturally to an upper planetary mass limit known as the “f
low isolation mass.” This mass scale naturally results in planetary growth
ending at super-Earth masses in the inner disk\, where\, in the absence o
f flow isolation\, rapid pebble accretion rates imply that planets either
stall at sub-Earth masses or run away to become gas giants.

ry\n\nSpeaker: Amit Sever\, CERN\n\nVideo: https://video.ias.edu/HETS/2019
/0916-AmitSever\n\nWe present a first-principles derivation of a weak-stro
ng duality between the four-dimensional fishnet theory in the planar limit
and a discretized string-like model living in AdS5. At strong coupling\,
the dual description becomes classical and we demonstrate explicitly the c
lassical integrability of the model. We test our results by reproducing th
e strong coupling limit of the 4-point correlator computed before non-pert
urbatively from the conformal partial wave expansion. Next\, by applying t
he canonical quantization procedure with constraints\, we show that the mo
del describes a quantum integrable chain of particles propagating in AdS5.
Finally\, we reveal a discrete reparametrization symmetry of the model an
d reproduce the spectrum when known analytically. Due to the simplicity of
our model\, it could provide an ideal playground for holography. Furtherm
ore\, since the fishnet model and N=4 SYM theory are continuously linked o
ur consideration could shed light on the derivation of AdS/CFT for the lat
ter. This talk is based on recent work with Nikolay Gromov.

University of California\, Los Angeles\n\nVideo: https://video.ias.edu/pui
as/2019/0917-TuanDo\n\nThe center of the Milky Way hosts the closest super
massive black hole and nuclear star cluster to the Earth\, offering us the
opportunity to study the physics of supermassive black holes and their en

1) Is General Relativity the correct description of supermassive black hol
es? (2) What is the nature of the near-infrared emission from Sgr A*? and
(3) How do nuclear star clusters form and evolve in the vicinity of a supe
rmassive black hole? I will show how the long time-baseline of Galactic ce
nter observations\, improved instrumental capabilities\, and use of statis

to these questions. I will discuss the measurement of the relativistic red
shift from the star S0-2 as it went through its closest approach to the su
permassive black hole in 2018\, Sgr A*'s unusual activity in 2019\, and th
e results from the first chemical-dynamical model of the Milky Way Nuclear

DESCRIPTION:Topic: A Look at Hadronization via High Multiplicity\n\nSpeaker
: Elena Kokoulina\, JINR-Dubna\n\nMultiparticle production is studied expe
rimentally and theoretically in QCD that describes interactions in the lan
guage of quarks and gluons. In the experiment the real hadrons are registe
red. For transfer from quarks and gluons to observed hadrons various pheno
menological models are used.In order to describe the high multiplicity reg
ion\, we offer a gluon dominance model (GDM). It represents a convolution
of two stages. First stage is described as a part of QCD. For second one (
hadronisation)\, the phenomenological model is used. To describe hadronisa
tion\, a scheme has been proposed\, consistent with experimental data in t
he region of its dominance. Comparison of this model with data on $e^+e^-$
annihilation over a wide energy interval (up to 200 GeV) confirms the fra
gmentation mechanism of hadronisation\, the development of the quark-gluon
cascade with energy increase with a domination of bremsstrahlung gluons.T
he description of topological cross sections in $pp$ collisions within of
GDM testifies that in hadron collisions the mechanism of hadronisation is
being replaced by the recombination one. At that point\, gluons play an ac
tive role in the multiparticle production process\, and valence quarks are
passive. They stay in the leading particles\, and only the gluon splittin
g is responsible for the region of high multiplicity.GDM with inclusion of
intermediate quark charged topologies describes topological cross section
s in a proton-antiptoton annihilation and explains linear growth of a seco
ndary correlative momentum in the negative area.The scaled variance of a n
eutral pion number mesuared by us is rising abruptly in the region of high
total multiplicity and differs from Monte Carlo predictions by seven stan
dard deviations. The growth of fluctuations of the neutral pion number in
this region may indicate the formation of a pion (Bose-Einstein) condensat
e. Despite the growth of fluctuations on the neutral number\, their averag
e remains equal to 1/3 of the total pion number.

DESCRIPTION:Topic: Circumplanetary Disk Dynamics in the Isothermal and Adia
batic Limits\n\nSpeaker: Jeffrey Fung\, Institute for Advanced Study\n\nTh
e dynamics of circumplanetary disks (CPDs)\, mini disks formed around prot
oplanets embedded in their natal protoplanetary disks\, is expected to reg
ulate how the planets accrete solids and gas\, as well as how satellite sy
stems are formed. Previous work have looked into the 3D dynamics of CPDs\,
but the limited parameter space explored and the lack of consensus on num
erical parameters\, such as resolution\, have led to disagreeing reports o
n CPD rotation rates and masses. Using the hydro codes PEnGUIn and Athena+
+\, we perform 3D hydrodynamics simulations and systematically sample the
parameter space to obtain measurements of CPD rotation rates and masses as
functions of planet mass\, in both the isothermal and adiabatic limits. T
hese two limits bracket the thermal evolution of the planet\, providing so
me insight into how the 3D dynamics changes as the planet cools. We find s
ignificant 3D flow and rotational support for all planet masses in the iso
thermal limit\, leading to a density structure that is not characterized b
y hydrostatic balance. I will describe these results in detail and discuss
their implications for planet accretion\, especially on how they may impa
ct our current understanding of gas giant formation.

oscopic survey that aims to discover and identify dwarf galaxy satellite s
ystems around Milky Way-like galaxies outside the Local Volume. The Survey
measures the satellite luminosity function in these systems down to the b
rightness of the Leo I galaxy\, and also the star formation rate of these
satellite galaxies. To date we have measured more than 17\,000 spectra\, i
dentified more than 100 satellite galaxies\, and obtained complete coverag
e around 21 host galaxies. The unprecedented datasets provide us new under
standings of our own Galaxy in a cosmological context and supply crucial i
ndgredients for the study of galaxy formation and the nature of dark matte
r. In this talk\, I will describe the design\, progress\, and current resu
lts of the SAGA Survey. I will discuss how our techniques can benefit futu
re low-redshift spectroscopic surveys\, and how we develop better theoreti
cal models to improve our understanding of the galaxy-halo connection at s
mall scales.

DESCRIPTION:Topic: The Quantum Black Hole: How Exotic Physics May Enter\n\n
Speaker: Gerard \'t Hooft\, Utrecht University\n\nQuantising a black hole
can be done starting with conventional physics. We just assume matter to k
eep the form of point particles until they come close to the horizon. The
gravitational back reaction of these particles generates a novel relation
between particles going in and particles going out\, enabling us to transf
orm in-going particles into out-going ones. This transformation removes “f
irewalls” along the future and past horizons\, but it strongly affects spa
ce-time inside a black hole. It subsequently allows us\, and indeed forces
us\, to identify antipodal points on the horizon. We argue that this exot
ic modification of the boundary condition is the only way to restore unita
rity for the quantum evolution operator\, and to identify the black hole m
icrostates. Some mysteries\, however\, remain unresolved.

DESCRIPTION:Topic: Relativistic Outflows in Neutron Star Mergers\n\nSpeaker
: Ore Gottlieb\, Tel Aviv University\n\nFollowing a double neutron star me
rger a relativistic jet propagates and interacts with the outflowing eject
a that surrounds the merger. As a result\, matter is pushed around the jet
to form a hot cocoon which applies pressure on the jet and potentially co
llimates it. After the jet breaks out from the merger ejecta\, the cocoon
expands and emits radiation over large angles throughout the entire electr
omagnetic spectrum. I will first discuss the evolution of the jet-cocoon s
ystem inside the ejecta. Then I will present the different emission mechan
isms of the jet+cocoon system\, from the first seconds to years later\, an
d how they compare with the set of observables in GW170817. I will conclud
e with what we expect from future events and what the jet-cocoon emission
can tell us about neutron star mergers and beyond.

DESCRIPTION:Topic: The Non-Local Non-Linear Sigma Model\n\nSpeaker: Christi
an Jepsen\, Princeton University\n\nIn this talk\, based on work with S. G
ubser\, Z. Ji\, B. Trundy\, and A. Yarom\, I present a scalar theory descr
ibed by an action given in terms of a bi-local integral of a power law fac
tor\, with an exponent parameter s\, multiplied by the squared arc length
between points on the target manifold. Depending on the choice of s and of
dimension\, the theory can reduce to the usual sigma model\, higher deriv
ative versions thereof\, or to a non-local theory with potential applicati
ons to the dynamics of M2-branes. I will also discuss the renormalization
of the theory at one-loop level.

DESCRIPTION:Topic: A Machine-Vision Method for Automatic Classification of
Stellar Halo Substructure\n\nSpeaker: Discussion Leader David Hendel\, Col
umbia University\n\nEach week\, we hold a relatively informal seminar/disc
ussion series in Peyton Hall with an emphasis on extra-galactic and large-
scale structure astrophysics. During Galread a leader/visitor presents a r
ecent paper to the discussion group. The PDF of the paper is projected ont
o a large screen\, and a guest explains the paper\, section by section\, i
n greater detail than may be explained within the text of the article. To
aid with discussion\, only the article PDF is presented -- no powerpoint-s
tyle slides. Galread discussions are very friendly and interactive. If you
would like to present at Galread\, please contact Andy Goulding (goulding
[at]astro.princeton.edu) or Jenny Greene (jgreene[at]astro.princeton.edu).
The group's website is: http://web.astro.princeton.edu/events/seminars/ga

DESCRIPTION:Topic: Fates of Exoplanets in Aging Binary Systems\n\nSpeaker:
Alexander Stephen\, University of California\, Los Angeles\n\nExoplanets h
ave been observed around a variety of host stars\, at all stages of stella
r evolution\, including main-sequence\, sub-giant and red giant branch sta
ges. Additionally\, white dwarf pollution signatures may indicate the pres
ence of planetary systems in a large fraction of white dwarf systems. More
over\, since the majority of stars are in binary configurations\, stellar
evolution for these systems can have large implications on the planetary d
ynamics. I will show that the post-main sequence evolution of these system
s leads to a variety of interesting phenomena\, such as the formation of H
ot Jupiters around evolved stars\, the consumption of planets by stars\, a
nd the pollution of white dwarfs with heavy elements. This is an informal
hour long meeting during which we discuss recent results in the field of e
xoplanets\, with occasional forays into stellar astrophysics and planetary
sciences as well. While most weeks are devoted to a discussion of recent
papers\, several times each semester we also host talks on these topics by
visitors. All are invited to attend\, and we especially encourage anyone\
, including students\, working in the field of exoplanets to come to these
meetings.

DESCRIPTION:Topic: Walking\, Weakly First Order Phase Transitions and Compl
ex CFTs\n\nSpeaker: Bernardo Zan\, Princeton University\n\nI will discuss
walking behavior in gauge theories and weakly first order phase transition
in statistical models. Despite being phenomena appearing in very differen
t physical systems\, they both show a region of approximate scale invarian
ce. They can be understood as a RG flow passing between two fixed points l
iving at complex couplings\, which we call complex CFTs. By using conforma
l perturbation theory\, knowing the conformal data of the complex CFTs all
ows us to make predictions on the observables of the walking theory. I wil
l also discuss some two-dimensional examples.

how machine learning\, with this natural language processing point of vie

DESCRIPTION:Topic: Intensity Mapping Tomography in Broadbands\n\nSpeaker: Y
i-Kuan Chiang\, Johns Hopkins University\n\nThe extragalactic background l
ight (EBL) provides a summary statistic of cosmological galaxy formation a
nd encodes information from all relevant physics in a light-weighted manne
r. However\, one needs to resolve key spectral features in the EBL in orde
r to extract the physics. For this\, we developed a cross-correlation base
d tomographic method to recover previously lost redshift and sub-bandpass
frequency information for the diffuse light in classic wide-field\, broadb
and imaging surveys. I will show the first application with data by probin
g the continuum\, Lyα line\, and Lyman break in the cosmic UV background (
UVB) up to z~2 using GALEX All Sky and Medium Imaging Surveys. These empir
ically constrained UVB spectral features provide insights on the cosmic st
ar formation history\, the absorption due to neutral gas in the interstell
ar medium\, and the potential emission from the diffuse intergalactic medi
um. We expect this method to be generically applicable over a wide range o
f wavebands\, with a potential of performing various spectral diagnostics
over the panchromatic EBL.

DESCRIPTION:Topic: Optimization Ideas\, Algorithms\, Tools\, and Some Astro
-Related Examples\n\nSpeaker: Robert Vanderbei\, Princeton University & In
stitute for Advanced Study\n\nIn science and engineering many problems can
be described as optimization problems. Many of these problems are somewha
t vaguely defined and are best solved by clever heuristics. But also\, man
y are very precisely defined and are best solved by carefully developed al
gorithms that quickly converge to an optimal solution. I work in this latt
er regime. In the talk I will define some of the types of constrained opti
mization problems for which efficient algorithms exist. I will then discus
s some of the issues that arise in expressing these problems so that the a
lgorithms run fast and I will give a brief introduction to one of the tool
s that makes this expression easy to do. Lastly\, I will illustrate these
ideas by discussing a few real examples that are relevant in the world of
astrophysics.

DESCRIPTION:Topic: 1I/’Oumuamua and 2I/Borisov\, the 1st & 2nd Interstellar
Objects Detected Passing Through the Solar System\n\nSpeaker: Casey Lisse
\, Johns Hopkins University\n\n1I/’Oumuamua (1I)\, the first clearly hyper
bolic object detected\, was announced the week of 23 Oct 2017 by PANSTARRS
as A/2017 U1\, and confirmed after the fact in Catalina Survey data. With
eccentricity e = 1.19\, it was clearly on a hyperbolic Interstellar traje
ctory. Coming from the sky direction of Vega\, it was as unbound as an e =
0.8 short period comet is bound to the Sun. The excess velocity of 1I aft
er it leaves the solar system\, ~10 km/sec\, is similar to the velocities
of stars in the local Solar neighborhood. As shown in images of 10+ observ
atories\, 1I was not actively outgassing\, despite the object passing with
in 0.25 AU of the Sun in early Sept 2017 and 0.20 AU of the Earth in Oct 2
017. Therefore it was rocky\, not icy\, like an asteroid.Measurements show
it to be small\, 3!) eccentricity was announced by the MPC. It had first
been detected by a Russian amateur astronomer\, Gennadiy Borisov\, on 30 A
ug 2019. This object is clearly extended in VSINIR imagery\, appearing lik
e a 'typical' active distant solar system comet with an ~8' wide coma and
20' long tail and a 1-10 km radius nucleus emitting 60 - 90 kg/sec of dust
. 2I/Borisov is acting like one would naively expect another system's exo-
Oort Cloud reject icy planetesimal should be acting when coming close to a
nother star after Myrs in deep ISM space\, and such active objects should
be much easier to discover and observe than small condensed objects like '
Oumuamua. The story of 2I is currently rapidly evolving\, as astronomers a
round the world (including this speaker) are scrambling to get telescope t
ime to further characterize this object. Fortunately we have time\, becaus
e unlike 1I/'Oumuamua\, 2I/Borisov is still coming into the inner system a
nd brightening\, with expected perihelion & perigee occurring in early Dec
ember 2019.In this talk\, I will logically and carefully\, using the scien
tific method\, discuss the likelihood of each of the possible scenarios me
ntioned above for the provenance of these objects. So far there is no reas
on to suspect that the natural process of exo-giant planet aggregation cou
ld not have created these objects and sent them hurtling through our syste
m.

aker: Shai Evra\, Member\, School of Mathematics\n\nVideo: https://video.i
as.edu/numbertheory/2019/0926-ShaiEvra\n\nIn their seminal work from the 8
0’s\, Lubotzky\, Phillips and Sarnak gave explicit constructions of topolo
gical generators for PU(2) with optimal covering properties. In this talk
I will describe some recent works that extend the construction of LPS to h
igher rank compact Lie groups. A key ingredient in the work of LPS is the
Ramanujan conjecture for U(2)\, which follows from Deligne's proof of the
Ramanujan-Petersson conjecture for GL(2). Unfortunately\, the naive genera
lization of the Ramanujan conjecture is false for higher rank groups. Foll
owing a program initiated by Sarnak in the 90's\, we prove a density hypot
hesis and use it as a replacement of the naive Ramanujan conjecture. This
talk is based on some joint works with Ori Parzanchevski and Amitay Kamber
.

DESCRIPTION:Topic: Aspects of Scattering Amplitudes and Moduli Space Locali
zation\n\nSpeaker: Sebastian Mizera\, Member\, School of Natural Sciences\
, IAS\n\nWe review a recent geometric formulation of the tree-level S-matr
ix of various quantum field theories\, including gauge and gravity theorie
s\, in terms of intersection numbers of twisted cohomology groups on the m
oduli space of genus-zero curves with marked points. Scattering amplitudes
are computed in terms of integrals over such moduli spaces that localize
on worldsheets resembling Feynman diagrams and in certain circumstances co
incide with the field-theory limit of string theory. We outline recursion
relations that allow for explicit computations of S-matrices on the forget
ful fibration of moduli spaces. We show that in the massless limit interse
ction numbers have another localization formula on the critical points of
a certain Morse function.

6D or 4D supergravity theory with gauge group SU(3) x SU(2) x U(1) / Z_6 a
nd associated generic matter. The concept of 'generic matter' can be rigor

ons for F-theory models. We describe general F-theory models with this gau
ge group and the associated generic matter content\, which fit into two di

hese models as two distinct branches. We also discuss\, as a special case\

peaker: Eiichiro Komatsu\, Max Planck Institute for Astrophysics\n\nVideo:
https://video.ias.edu/astrophysics/2019/1001-EiichiroKomatsu\n\nThe cosmi
c microwave background (CMB) research told us a remarkable story: the stru
cture we see in our Universe such as galaxies\, stars\, planets\, and even
tually ourselves originated from tiny quantum fluctuations generated in th
e early Universe. With the WMAP we have confirmed many of the key predicti
ons of inflation including flatness and statistical homogeneity of our Uni
verse\, Gaussianity and adiabaticity of primordial density fluctuations\,
and a small but non-zero deviation from the scale-invariant spectrum of de
nsity fluctuations. Yet\, the extraordinary claim requires extraordinary e
vidence. The last prediction of inflation that is yet to be confirmed is t
he existence of primordial gravitational waves whose wavelength can be as
big as billions of light years. To this end we have proposed to JAXA a new
satellite mission called LiteBIRD\, whose primary scientific goal is to f
ind signatures of gravitational waves in the polarisation of the CMB. In t
his presentation we describe physics of gravitational waves from inflation
including both the vacuum and sourced contributions (i.e.\, left and righ
t hands of Einstein’s equation)\, the LiteBIRD proposal\, as well as a sub
-mm telescope in Chile called CCAT-prime that we are currently building.

Sanjoy Dasgupta\, University of California\, San Diego\; Special Year Mem

xpand-and-sparsify'\, appears in the olfactory system of the fly and the s
ensory systems of several other organisms. It maps an input vector to a mu
ch higher-dimensional sparse representation\, using a random linear transf
ormation followed by winner-take-all thresholding. I'll show that this rep
resentation has a variety of formal properties\, such as (1) locality pres
ervation\, (2) universal approximation\, and (3) adaptivity to manifold st
ructure\, that make it an attractive data structure for algorithms and mac
hine learning. In particular\, mimicking the fly's circuitry yields algori
thms for similarity search and for novelty detection that have provable gu
arantees as well as being effective in practice. This talk is based on wor

DESCRIPTION:Topic: Probing Nonperturbative Structures in Gravity with SYK M
odel\n\nSpeaker: Mikhail Khramtsov\, Steklov Institute\n\nMy talk is devot
ed to studies of large N saddle point structures in the SYK model beyond t
he commonly used approximations\, in particular the replica-diagonal assum
ption and the conformal limit. We will discuss new solutions of the saddle
point equations in the SYK and their role in physics of the model and in
the gravity dual description. We will focus on the replica-nondiagonal exa
ct saddle points\, which introduce small nonperturbative effects in the 1/
N expansion of SYK. We will consider their properties and implications for
the gravity dual\, a UV completion of JT gravity.\nThe talk is based on p
apers arXiv:1811.04831\, arXiv:1905.04203 and on current work in progress.

DESCRIPTION:Topic: Looking for Axion Dark Matter: From Dwarf Galaxies to Pu
lsars\n\nSpeaker: Andrea Caputo\, Valencia University\n\nAxion and Axion-l
ike particles are fascinating dark matter candidates and a great effort ha
s been devoted to their study\, both theoretically and experimentally. In
this talk I will discuss two different astrophysical searches. The first o
ne consists in looking with radio telescopes for the spontaneous decay of
axion dark matter using different targets as Dwarf Galaxies\, Clusters or
the Galactic Center. The second one uses the parity violating axion intera
ctions to exploit the extreme precision of pulsar timing measurements and
look for oscillations in the polarization angle of the pulsar signal.

DESCRIPTION:Topic: Do Supernovae-driven Hot Outflows Shape the Circumgalact
ic Medium?\n\nSpeaker: Miao Li\, Simons Foundation\n\nSupernovae (SNe) dri
ve metal-enriched\, galaxy-wide outflows. How the outflows impact the circ
umgalactic medium (CGM) depends on (a) how much mass/energy/metals the out
flows carry\, and (b) what is already in the CGM. Small-box\, high-resolut
ion simulations on SNe feedback constrain (a) but leave out (b)\, whereas
cosmological simulations capture (b) but use ad hoc models for (a). We aim
at bridging the gap by adopting small-box results as the outflow model fo
r galaxy-scale simulations to study the resultant CGM. In this talk\, I wi
ll first summarize the recent progress of small-box simulations\; particul
arly\, the hot outflows appear to be simple yet powerful. Using a Milky Wa
y-mass galaxy for an example\, we find that\, when the star formation surf
ace density is low\, hot outflows form large-scale fountains in the halo.
The warm-hot CGM has a universal density profile\, which produces the obse
rved column density of O VI\, VII\, and VIII\, and X-ray emission. Cool ga
s that condenses out of the hot CGM is highly enriched and mainly falls to
ward the galaxy. In contrast\, when the star formation surface density is
high\, the outflows are bipolar in shape and funnel metals into the interg
alactic medium\; cool gas is moderately-enriched\, with a fraction moving
outward at high velocities.

r: Kento Masuda\, Institute for Advanced Study\n\nThe prime Kepler mission
provided high-precision photometric light curves for 10^5 stars continuou
sly over 4 years. While the search for exoplanetary transits in these data
was originally focused on signals with periods less than about a year\, d
edicated searches performed by several groups (including ours) in the past
few years have uncovered the signals with longer periods. I will discuss
how the population of long-period transiting exo-Jupiters from these searc
hes\, when combined with the information from Doppler surveys for the same
type of planets\, constrains the flatness of exoplanetary systems hosting
exo-Jupiters. I will also present self-lensing white dwarf binaries found
from the same searches\, including a mysterious system that may challenge
our current understanding on the formation of extremely low-mass white dw
arfs in binaries.

DESCRIPTION:Topic: Shattering of Cosmic Sheets Due to Thermal Instabilities
: A Formation Channel for Metal-Free Lyman Limit Systems\n\nSpeaker: Nir M
andelker\, Yale University\n\nWe present a new cosmological zoom-in simula
tion\, where the zoomed region consists of two massive halos\, $M_{\rm vir
}\gsim 5\times 10^{12}\msun$ at $z\gsim 2$\, and a giant\, $\sim \Mpc$ lon
g filament connecting them. Using this simulation\, we study the evolution
of the intergalactic medium (IGM) in between the two main halos at redshi
fts $5>z>3$ at unprecedented resolution. At $5\gsim z \gsim 3$\, the two h
alos are found to lie in a large intergalactic sheet\, or pancake'\, consi
sting of multiple co-planar dense filaments along which nearly all halos w
ith $M_{\rm vir}>10^9\msun$ are located. These filaments merge within the
sheet\, forming the single large filament connecting the two halos at $z\g
sim 2$. This sheet collapses at $z\gsim 5$ from the merger of two smaller
super-galactic sheets. The strong shock generated by this merger leads to
thermal instabilities in the post-shock region\, and to a shattering of th
e sheet resulting in $\lsim \kpc$ scale clouds with temperatures of $T\gsi
m 2\times 10^4\K$ and densities of $n\gsim 10^{-3}\cmc$ pressure confined
in hot medium with $T\sim 10^6\K$ and $n\gsim 10^{-5}\cmc$. When the sheet
is viewed face on\, these cold clouds have neutral Hydrogen column densit
ies of $\nHI>10^{17.2}\cms$\, making them detectable as Lyman limit system
s (LLSs)\, though they lie well outside the virial radius of any halo and
even well outside the dense filaments. Their chemical composition is thus
pristine\, having zero metalicity\, similar to several recently observed s
ystems. Since these systems form so far from any galaxies\, these results
are robust to the galaxy formation physics\, resulting purely from the col
lapse of large scale structure\, radiative cooling\, and sufficient spatia
l resolution.

DESCRIPTION:Topic: The Life and Death of Stellar Nurseries: GMCs and Stella
r Clusters in Cosmological Simulations\n\nSpeaker: Samantha Benincasa\, Un
iversity of California\, Davis\n\nThe connection between GMCs and star for
mation is complex\, involving both the detailed structure of dense gas and
the influence of the larger galactic environment. Modelling the connectio
n between GMCs\, stellar clusters\, and galaxy-wide properties within in a
cosmological setting has been difficult given the dynamic ranges involved
. However\, the Latte suite of FIRE-2 cosmological zoom-in simulations of
Milky Way-type galaxies now allows us to do so\, given their unprecedented
adaptive spatial resolution down to 1 pc\, able to resolve cloud-wide pro
perties within a larger galactic environment. We present one of the first
analyses of the properties of GMCs formed in the FIRE-2 cosmological simul
ation\, showing intriguing first results on the distribution of GMCs and t
he interaction of these entities with stellar clusters\, with focus on the
role of these clusters in dispersing their birth environments. We find th
at clouds live no longer than 20 Myr and favour short lifetimes\, on the o
rder of 6 Myr. This suggests a large role for early stellar feedback and t
he galactic environment in shaping cloud lifetimes. If time allows\, I wil
l discuss new results on the role of radiative transfer and FUV heating in
shaping the galactic environment using the simulation code Gasoline.

DESCRIPTION:Topic: Magic Angle Twisted Bilayer Graphene\n\nSpeaker: Allan H
. MacDonald\, University of Texas at Austin\n\nMoiré patterns are ubiquito
us in layered van der Waals materials and can now be fabricated with consi
derable control by combining mechanical exfoliation of van der Waals layer
s with tear and stack device fabrication techniques. I will explain why th
e electronic and optical properties of two-dimensional semiconductors and
semimetals are strongly altered in long-period moiré superlattices\, focus
ing in particular on the remarkable example of twisted bilayer graphene. W
hen twisted to a magic [1] relative orientation angle near 1 degree the mo
iré superlattice minibands of bilayer graphene become extremely narrow and
electronic correlations become strong. Experimental studies [2] of magic-
angle twisted bilayer graphene (MATBG) have demonstrated that the electron
ic ground state can be a superconductor\, a metal\, or an insulator\, depe
nding on the filling of the magic angle flat bands. Insulating states occu
r close to most integer values of the number of electrons per moiré superl
attice period\, whereas superconducting states are common at fractional mo
iré band filling factors. In some cases\, the insulating states are purely
orbital ferromagnets that exhibit a quantum anomalous Hall effect and hav
e superlattice bands with non-zero topological Chern indices C. I will dis
cuss progress that has been made toward understanding these remarkable pro
perties.[1] Moire bands in twisted double-layer graphene\, R. Bistritzer a

DESCRIPTION:Topic: A stacky approach to crystalline (and prismatic) cohomol
ogy.\n\nSpeaker: Vladimir Drinfeld\, The University of Chicago\; Visiting
Professor\, School of Mathematics\n\nVideo: https://video.ias.edu/puias/20
19/1003-VladimirDrinfeld\n\nThe stacky approach was originated by Bhatt an
d Lurie. (But the possible mistakes in my talk are mine.)\n\nLet X be a sc
heme over F_p. Many years ago Grothendieck and Berthelot defined the notio
n of crystal on X\; moreover\, they defined the notion of crystalline coho
mology of a crystal.\n\nI will give several equivalent definitions of a st
ack X^{prism} such that a crystal on X is the same as a quasi-coherent O-m
odule on X^{prism} and the crystalline cohomology of a crystal is just the
cohomology of this O-module. The stack X^{prism} is algebraic (in a certa
in sense).\n\nIf time permits\, I will explain how to modify the definitio
n of X^{prism} to get prismatic cohomology (this is a new theory due to Bh
att-Scholze\, in which X is an arbitrary p-adic formal scheme rather than
an F_p-scheme).

Zhang\n\nA sunflower with $r$ petals is a collection of $r$ sets so that t
he intersection of each pair is equal to the intersection of all. Erdos an
d Rado in 1960 proved the sunflower lemma: for any fixed $r$\, any family
of sets of size $w$\, with at least about $w^w$ sets\, must contain a sunf
lower. The famous sunflower conjecture is that the bound on the number of
sets can be improved to $c^w$ for some constant $c$. Despite much research
\, the best bounds until recently were all of the order of $w^{cw}$ for so
me constant c. In this work\, we improve the bounds to about $(log w)^w$.

DESCRIPTION:Topic: Line-intensity Mapping with the CO Mapping Array Pathfin
der\n\nSpeaker: Dongwoo Chung\, Stanford University\n\nLine-intensity mapp
ing—the observation of aggregate emission in various atomic and molecular
spectral lines—is an emerging technique with tremendous potential to shed
light on how the first stars and galaxies formed\, as well as on subsequen
t early-universe star formation and galaxy formation. The CO Mapping Array
Pathfinder (COMAP) is one of the first single-dish line-intensity mappers
to come online targeting intermediate-to-high redshift. In addition to ha
ving strong scientific motivation on its own—probing molecular gas near th
e peak of cosmic star-formation activity—the initial phase of COMAP will s
erve as a testing ground for experimental\, analytic\, and modelling techn
iques to be used in more ambitious future surveys. This talk will consider
the basic ideas behind CO line-intensity mapping\, discuss potential obst
acles against and catalysts for COMAP science\, and reflect on the program
me’s present state and possible futures.Organizers are Jo Dunkley\, Prince
ton University\, and Matias Zaldarriaga\, Institute for Advanced Study. Th
e lunch will be held either at Princeton University or the Institute for A
dvanced Study. Check the calendar for the meeting location. This week's me
eting is at Princeton University. Attendees can bring lunch.

DESCRIPTION:Topic: Supersymmmetric Lifshitz Field Theories\n\nSpeaker: Avia
Raviv-Moshe\, Tel-Aviv University\n\nLifshitz scaling is an anisotropic s
caling where time and space scale differently. Quantum field theories that
exhibit Lifshitz scale symmetry provide a framework for studying low ener
gy systems with an emergent dynamic scaling such as quantum critical point
s. Introducing supersymmetry to the Lifshitz algebra leads to a rich struc
ture that is less constrained compared to that of relativistic supersymmet
ry. We construct supersymmetric Lifshitz quantum field theories and study
their renormalization properties and RG flows. We show that models of Lifs
hitz supersymmetry that possess a holomorphic structure realize lines of q
uantum exact Lifshitz fixed points for various choices of spacetime dimens
ions and marginal supersymmetric interactions. The presented results are b
ased on two papers.

eo: https://video.ias.edu/symplectic/2019/1007AgustinMoreno\n\nStarting fr
om a contact manifold and a supporting open book decomposition\, an explic
it construction by Bourgeois provides a contact structure in the product o
f the original manifold with the two-torus. In this talk\, we will discuss
recent results concerning rigidity and fillability properties of these co
ntact manifolds. For instance\, it turns out that Bourgeois contact struct
ures are\, in dimension 5\, always tight\, independent on the rigid/flexib
le classification of the original contact manifold. Moreover\, Bourgeois m
anifolds associated to suitable monodromies provide new examples of weakly
but not strongly fillable contact 5-manifolds. We also present the follow
ing application in any dimension: the standard contact structure in the un
it cotangent bundle of the n-torus\, which is a Bourgeois manifold\, admit
s a unique aspherical filling up to diffeomorphism. This is joint work wit
h Jonathan Bowden and Fabio Gironella.

Weizmann Institute of Science\; Member\, School of Mathematics\n\nVideo:
https://video.ias.edu/tml/2019/1008-BoazNadler\n\nIn various applications\
, one is given the advice or predictions of several classifiers of unknown
reliability\, over multiple questions or queries. This scenario is differ
ent from standard supervised learning where classifier accuracy can be ass
essed from available labeled training or validation data\, and raises seve
ral questions: given only the predictions of several classifiers of unknow

a) reliably rank them\, andb) construct a meta-classifier more accurate th
an any individual classifier in the ensemble? In this talk we'll show that
under various independence assumptions between classifier errors\, this h
igh dimensional data hides simple low dimensional structures. Exploiting t
hese\, we will present simple spectral methods to address the above questi

methods are asymptotically consistent when the model assumptions hold\, a
nd present their empirical success on a variety of unsupervised learning p

: Andrea Dei\, ETH Zürich\n\nString theory on AdS3xS3xT4 with one unit of
NSNS flux has been recently argued to be dual to the symmetric product orb
ifold of T^4. The duality has been extended to the case of generic NSNS ba
ckground flux. I will consider the bosonic version of this duality and sho
w how to match null-vector constraints on three-point functions. I will ex
plain how some three-point functions can be explicitly derived and matched
on the two sides of the duality. This amounts to one of the very first ho
lographic matches of non-protected AdS3/CFT2 correlators.

DESCRIPTION:Topic: Conformal Freeze in\n\nSpeaker: Sungwoo Hong\, Cornell U
niversity\n\nConventionally\, the main focus for the cosmic evolution of o
ur universe has been on descriptions in terms of particles: dark matter (D
M) as massive particle\, and dark radiation\, if existing at all\, in the
form of massless or very light particle. In this talk\, I will discuss a s
cenario where conformal field theory (CFT) plays a crucial role in cosmolo
gy\, especially production of naturally light dark matter. When the Standa
rd Model (SM) couples to a sector of CFT\, I will argue that in the regime
where only the SM sector gets reheated\, the energy density of the CFT se
ctor is populated via energy injection from the SM (conformal freeze-in) a
nd can be reliably computed. Such CFT energy density\, redshifting like a
radiation\, will not account for DM unless somehow a mass gap is generated
in the CFT. Remarkably\, such a gap scale is dynamically generated due to
phase transitions of SM: electroweak and QCD. In this way\, DM energy tod
ay is produced in the early universe when it is not in gapped particle sta
te\, but a CFT state. Moreover\, DM mass scale consistent with observed re
lic density and other observational constraints (mostly bullet cluster and
warm dark matter bounds) turns out to be less than MeV. Therefore\, confo
rmal freeze-in provides a framework for naturally light DM.

DESCRIPTION:Topic: Designing Fast and Robust Learning Algorithms\n\nSpeaker
: Yu Cheng\, University of Illinois at Chicago\n\nVideo: https://video.ias
.edu/tml/2019/1009-YuCheng\n\nMost people interact with machine learning s
ystems on a daily basis. Such interactions often happen in strategic envir
onments where people have incentives to manipulate the learning algorithms
. As machine learning plays a more prominent role in our society\, it is i
mportant to understand whether existing algorithms are vulnerable to adver
sarial attacks and\, if so\, design new algorithms that are robust in thes
e strategic environments. In this talk\, I will focus on two lines of my w
ork on leveraging these recent advancements to design fast and provably ro
bust learning algorithms: making non-convex matrix completion approaches r
obust against semi-random adversaries\, and designing robust high-dimensio
nal statistical estimators that can be computed almost as efficiently as t
heir non-robust counterparts. Most of the talk is based on joint work with
Ilias Diakonikolas and Rong Ge.

: Remy van Dobben de Bruyn\, Veblen Research Instructor\, School of Mathem

polynomial $f : \mathbb C^n \to \mathbb C^n$ is also surjective. It is on
e of the first examples of the powerful technique in algebraic geometry of
using finite fields to prove results over the complex numbers. We will gi

DESCRIPTION:Topic: Universal Interferometric Signatures of a Black Hole's P
hoton Ring\n\nSpeaker: Alex Lupsasca\, Harvard University\n\nThe Event Hor
izon Telescope image of the supermassive black hole in the galaxy M87 is d
ominated by a bright\, unresolved ring. General relativity predicts that e
mbedded within this image lies a thin ``photon ring\,' which is composed o
f an infinite sequence of self-similar subrings that are indexed by the nu
mber of photon orbits around the black hole. The subrings approach the edg
e of the black hole ``shadow\,' becoming exponentially narrower but weaker
with increasing orbit number\, with seemingly negligible contributions fr
om high order subrings. I will argue that these subrings produce strong an
d universal signatures on long interferometric baselines. These signatures
offer the possibility of precise measurements of black hole mass and spin
\, as well as tests of general relativity\, using only a sparse interferom
etric array.

DESCRIPTION:Topic: Extreme Orbital Evolution of Few-Body systems: From the
Solar System to Gravitational Waves\n\nSpeaker: Evgeni Grishin\, Israel In
stitute of Technology\n\nTriple and multiple systems are ubiquitous in nat
ure and arise in many different scales and configurations. In hierarchical
triple systems\, the inner binary is perturbed by a distant companion. Fo
r large mutual inclinations\, the Lidov–Kozai (LK) mechanism secularly exc
ites the eccentricity of the inner binary to large values. We analytically
study the breakdown of the secular approximation and find that the maxima
l eccentricity is generally enhanced\, allowing closer encounters between
the inner binary components\, leading to a plethora of possible outcomes.
We apply our results to several systems: (1) We find the Hill-stability li
mit of irregular satellites and reproduce their observed inclination distr
ibution. (2) We show that non-secular evolution could be responsible for t
he formation of contact binaries such as (2014) MU_69 (Ultima-Thule) from
wide binaries in the Kuiper Belt. (3) We show that more Hot-Jupiters shoul
d be disrupted from larger distances. (4) We include general relativistic
corrections and find a lower bound for the maximal eccentricity in 2.5 Pos
t-Newtonian evolution. We use direct integrations to show that the merger
rate of binary Black Holes and Neutron Stars in individual galactic nuclei
is greater than previously considered by an order of magnitude\, but the
final rate is uncertain due to uncertainties in star formation history and
supply rate. If time permits I'll discuss the future research directions
of multiple interacting systems\, including chaotic dynamics\, stellar and
planetary evolution\, and Galactic and cluster tidal potential.

DESCRIPTION:Topic: A (Massive) Star Is Born: How Stellar Feedback Limits Ac
cretion onto Massive Stars\n\nSpeaker: Anna Rosen\, Harvard University\n\n
Massive stars play an essential role in the Universe. They are rare\, yet
the energy and momentum they inject into the interstellar medium (ISM) wit
h their intense radiation fields dwarfs the contribution by their vastly m
ore numerous low-mass cousins. Massive stars form in magnetized\, dense\,
and cold molecular gas from the gravitational collapse of massive pre-stel
lar cores located in highly embedded environments. During their formation\
, feedback from their intense radiation fields\, magnetically launched col
limated protostellar outflows\, and fast\, isotropic radiatively driven wi
nds can limit their growth by accretion. In this talk\, I will show a seri
es of radiation- magnetohydrodynamic (RMHD) simulations of the collapse of
massive pre-stellar cores into massive stellar systems that include these
feedback processes to demonstrate how stellar feedback can limit accretio
n onto massive stars. Furthermore\, I will also discuss how stellar feedba
ck from massive stars\, which are born in clustered environments\, affects
the dynamics of HII regions that surround these clusters and can drive IS
M turbulence in young\, star clusters.

DESCRIPTION:Topic: dS Thermodynamics from Bulk and Horizon Characters\n\nSp
eaker: Zimo Sun\, Columbia University\n\nIn this talk\, I will discuss the
idea that the exact one-loop free energy of the static patch of D-dimensi
onal de Sitter space can be computed as a simple integral transform of an
SO(1\;D) bulk character corrected by an SO(1\; D-2) edge character\, for f
ields of arbitrary mass and spin. The bulk character captures the particle
content of the theory and counts quasinormal modes in the bulk. The edge
character counts edge modes on the horizon. I will also show the applicati
on of this formalism in 4D and 3D dS Vasiliev gravity. In the 4D case\, af
ter summing over spins\, there is a huge cancellation between the bulk and
edge characters\, leaving the character of a scalar living in three dimen
sions. In the 3D case\, I will discuss its relation with Chern Simons theo
ry.

istics of quantum graphs\n\nSpeaker: Lior Alon\, Technion\n\nVideo: https:
//video.ias.edu/analysis/2019/1011-LiorAlon\n\nWe consider Laplace eigenfu
nctions of a metric graph satisfying Neumann-Kirchhoff conditions on every
vertex. The nodal count of a given eigenfunction is the number of points
at which it vanishes. The nodal count of the n-th eigenfunction was shown
to be bounded between n-1 and n-1+\beta\, where \beta if the first Betti n
umber of the graph. The difference between the nodal count and n-1 is call
ed the nodal surplus. Berkolaiko et al. showed that the n-th nodal surplus
equals to a magnetic stability index of the n-th eigenvalue. We present r
ecent results on the statistics of the nodal surplus and conjecture a univ
ersal behavior for large graphs. This talk is based on joint works with Ra
m Band (Technion) and Gregory Berkolaiko (Texas A&M).

DESCRIPTION:Topic: Nodal domains of equivariant eigenfunctions on Kaluza-Kl
ein $3$-folds.\n\nSpeaker: Junehyuk Jung\, Texas A&M University\n\nIn this
talk\, I'm going to explain my recent work with Steve Zelditch\, where we
prove that\, when $M$ is a principle $S^1$-bundle equipped with a generic
Kaluza-Klein metric\, the nodal counting of eigenfunctions is typically $
2$\, independent of the eigenvalues. Note that principle $S^1$-bundle equi
pped with a Kaluza-Klein metric never admits ergodic geodesic flow. This\,
for instance\, contrasts the case when $(M\,g)$ is a surface with non-emp
ty boundary with ergodic geodesic flow (billiard flow)\, in which case the
number of nodal domains of typical eigenfunctions tends to $+\infty$. I w
ill also present an orthonormal eigenbasis of Laplacian on a flat 3-torus\
, where every non-constant eigenfunction has exactly two nodal domains. In
particular\, this tells us that the number of nodal domain could be unifo
rmly bounded independent of the eigenvalue.

DESCRIPTION:Topic: Constraining Primordial Black Hole Scenarios with 21 cm
Cosmology\n\nSpeaker: Pablo Villanueva-Domingo\, Instituto de Física Corpu
scular\n\nThe discoveries of a number of binary black hole mergers by LIGO
and VIRGO has reinvigorated the interest that primordial black holes (PBH
s) of tens of solar masses could contribute non-negligibly to the dark mat
ter energy density. Should even a small population of PBHs with masses ~ O
(M_sun) exist\, they could profoundly impact the properties of the interga
lactic medium and provide insight into novel processes at work in the earl
y Universe. We demonstrate here that observations of the 21cm transition i
n neutral hydrogen during the epochs of reionization and cosmic dawn will
likely provide one of the most stringent tests of solar mass PBHs. In the
context of 21cm cosmology\, PBHs give rise to two distinct observable effe
cts: (i) the modication to the primordial power spectrum (and thus also th
e halo mass function) induced by Poisson noise\, and (ii) a uniform heatin
g and ionization of the intergalactic medium via X-rays produced during ac
cretion. Using a four-parameter astrophysical model\, we show that experim
ents like SKA and HERA could potentially improve upon existing constraints
derived using observations of the cosmic microwave background by more tha
n one order of magnitude.

MB data on many galaxies for which the spin orientation can be estimated s

the galaxies' projected spin\, and scaled to their halos' angular size. Or

DESCRIPTION:Topic: Finding structure in high dimensional data\, methods and
fundamental limitations\n\nSpeaker: Boaz Nadler\, Weizmann Institute of S
cience\; Member\, School of Mathematics\n\nVideo: https://video.ias.edu/me
mbers/2019/1017-BoazNadler\n\nA fundamental task in (unsupervised) analysi
s of data is to detect and estimate interesting 'structure' hidden in it.
In low dimensions\, this task has been explored for over 100 years with do
zens of developed methods. In this talk I'll focus on aspects of this prob
lem for high dimensional data\, where each observation has many coordinate
s. We will show that (i) standard methods to detect structure in high dime
nsions may not work well\, and there is a need to devise new models and ap
proaches\; and yet\, (ii) with a limited amount of high dimensional observ
ations\, regardless of the method employed\, there are fundamental limitat
ions to the ability to detect various structures\, even if they are presen
t in the data.

DESCRIPTION:Topic: Entanglement Wedge Reconstruction and the Information Pa
radox\n\nSpeaker: Geoff Penington\, Stanford University\n\nWhen absorbing
boundary conditions are used to evaporate a black hole in AdS/CFT\, we sho
w that there is a phase transition in the location of the quantum Ryu-Taka
yanagi surface\, at precisely the Page time. The new RT surface lies sligh
tly inside the event horizon\, at an infalling time approximately one scra
mbling time in the past. We can immediately derive the Page curve\, using
the Ryu-Takayanagi formula\, and the Hayden-Preskill decoding criterion\,
using entanglement wedge reconstruction. Becausepart of the interior is no
w encoded in the early Hawking radiation\, the decreasing entanglement ent
ropy of the black hole is exactly consistent with the semiclassical bulk e
ntanglement of the late-time Hawking modes\, despite the absence of a fire
wall. By studying the entanglement wedge of highly mixed states\, we can u
nderstand the state dependence of the interior reconstructions. Directly a
fter the Page time\, interior operators can only be reconstructed from the
Hawking radiation if the initial state of the black hole is known. As the
black hole continues to evaporate\, reconstructions become possible that
simultaneously work for a large class of initial states. This state depend
ence provides the mechanism by which information that falls into the black
hole eventually escapes in the Hawking radiation.

DESCRIPTION:Topic: Inscribing Rectangles in Jordan Loops\n\nSpeaker: Rich S
chwartz\, Brown University\n\nVideo: https://video.ias.edu/sympdyngeo/2019
/1017-RichSchwartz\n\nI'll show a graphical user interface I wrote which e
xplores the problem of inscribing rectangles in Jordan loops. The motivati
on behind this is the notorious Square Peg Conjecture of Toeplitz\, from 1
911.I did not manage to solve this problem\, but I did get the result that
at most 4 points of any Jordan loop are vertices of inscribed rectangles.
I will sketch a proof of this result\, mostly through visual demos\, and
also I will explain two other theorems about inscribed rectangles which at
least bear a resemblance to theorems in symplectic geometry.

l transport problem\, it is well-known that the geometry of the target dom
ain plays a crucial role in the regularity of the optimal transport. In th
e quadratic cost case\, for instance\, Caffarelli showed that having a con
vex target domain is essential in guaranteeing the optimal transport’s con

convexity is in producing continuous optimal transports.

Speaker: Malte Buschmann\, University of Michigan\n\nWe perform high resol

oken after inflation starting at the epoch before the PQ phase transition
and ending at matter-radiation equality. We characterize the spectrum of p
rimordial perturbations that are generated and comment on implications for
efforts to detect axion dark matter (DM). We also measure the DM density
at different simulated masses and argue that the correct DM density is obt
ained for an axion mass of 25.2 ± 11.0 µeV.

DESCRIPTION:Topic: Disruption of Giant Molecular Clouds and Formation of Bo
und Star Clusters Under the Influence of Momentum Stellar Feedback\n\nSpea
ker: Hui Li\, Massachusetts Institute of Technology\n\nEnergetic feedback
from massive stars plays a pivotal role in shaping the dynamical evolution
of giant molecular clouds (GMCs). In this talk\, I will present a suite o
f isolated GMC simulations to investigate how stellar feedback affects the
star formation efficiency (SFE) and the subsequent dynamical response of
embedded star clusters. We find that the SFE of the clouds scales strongly
with the initial cloud surface density and momentum feedback strength. Th
e boundness of the resulting star clusters is a continuously increasing fu
nction of SFE. GMCs with efficiency much smaller than 0.5 are still able t
o form clusters with large bound fractions. The initial density profile of
clouds\, though has little effect on the SFE\, controls the mode of star
formation. Clouds with shallower profiles form stars bottom-up\, while hig
hly-concentrated clouds form massive star clusters at the center\, which g
radually accrete mass from the cloud outskirt later. In the end\, I will b
riefly talk about our preliminary results on how dust dynamics enhance the
effects of ionizing radiation from massive stars.

DESCRIPTION:Topic: Mid-band Atomic Gravitational wave Interferometric Senso
r (MAGIS)\n\nSpeaker: Peter Graham\, Stanford University\n\nGravitational
waves provide a new window to the universe. Opening new bands in the gravi
tational spectrum is expected to yield a wealth of information. I will dis
cuss a new experiment: the Mid-band Atomic Gravitational wave Interferomet
ric Sensor (MAGIS). MAGIS aims to observe gravitational waves in the mid-f
requency band\, roughly 0.01 - 10 Hz\, between the LIGO and LISA bands. It
relies on high precision atomic interferometry\, similar to atomic clock
technology\, and a long laser baseline to achieve the necessary sensitivit
y. We have just begun construction of a 100 meter prototype of this detect
or at Fermilab. I will discuss the design\, status\, and prospects of this
detector\, as well as some of the science available in the mid-band. For
example\, even for sources that would later be observed by LIGO\, observat
ion in the mid-band allows greatly improved angular localization and hence
the ability to predict the time and location of an upcoming merger well b
efore it happens. The mid-band also allows observation of new sources that
are not available in other bands.

DESCRIPTION:Topic: Increased Hubble Tension with a New Measurement of the H
ubble Constant Using Strong Lensing\n\nSpeaker: Anowar Shajib\, University
of California\, Los Angeles\n\nThe recent tension between early- and late
-Universe measurements of the Hubble constant highlights the necessity for
independent and precise probes such as the time-delay cosmography. The me
asured time-delays between the lensed images of a background quasar depend
on the absolute physical scales in the lens configuration. Thus\, they al
low measurement of these scales to infer the Hubble constant\, H_0. Due to
a number of great advancements over the past decade in both the data qual
ity and modeling techniques\, the measurement of H_0 from the time-delays
has already become competitive with other traditional methods such as the
cosmic distance ladder. This is evident from the recent 2.4% blind measure
ment of H_0 from only six lenses (Wong et al. 2019). Recently\, I have ana
lyzed one new lens system to infer H_0 with the highest precision from a s
ingle lens system to date. This new measurement brings the combined uncert
ainty from time-delay cosmography to 2%—which is comparable to the SH0ES m
easurement—and increases the tension with the early-Universe probes. Lastl
y\, I will present the future roadmap of time-delay cosmography to indepen
dently reach 1% precision within a few years.

DESCRIPTION:Topic: Using Metals and Stars to Constrain Galaxies’ Past Gaseo
us Inflows and Outflows\n\nSpeaker: Grace Telford\, Rutgers\, The State Un
iversity of New Jersey\n\nAs galaxies evolve\, they must enrich and exchan
ge gas with the surrounding medium\, but the timing of these processes and
how much gas is involved remain poorly constrained. In this talk\, I pres
ent my work using observations of the metal and stellar content of galaxie
s to constrain the history of gas inflow and outflow processes in the loca
l universe. First\, I discuss the relationship between stellar mass (M*)\,
gas-phase metallicity (Z)\, and star formation rate across the local gala
xy population\, which is thought to encode the strength and duration of me
tal dilution events due to inflows of metal-poor gas and/or metal-enriched
outflows. I show that possible biases in the inferred M* and Z can alter
the apparent strength of the correlation\, and therefore its physical inte
rpretation. I then focus on the nearby massive spiral galaxy M31\, where h
igh-quality\, spatially resolved measurements of star formation history (S
FH) and dust content and geometry enable a test of standard M* inference t
echniques. I demonstrate that both recent star formation and variation in
star-dust geometry can bias the M* inferred from state-of-the-art models.
Finally\, I use the same SFHs to calculate the metal mass lost via gaseous
outflows from M31 over its lifetime. I calculate the implied metallicity
of the circumgalactic medium and show that metals have been redistributed
out of the central disk during the last ~1.5 Gyr.

DESCRIPTION:Topic: The Expansion of the Universe\, Faster than We Thought\n
\nSpeaker: Adam Riess\, Johns Hopkins University & Space Telescope Science
Institute\n\nOne of the few ways we can learn about the composition\, age
and fate of the Universe is by measuring its expansion rate and its expan
sion history. Assuming that the Universe is homogeneous and isotropic on l
arge scales and that it obeys General Relativity\, we can derive an equati
on of motion for the Universe\, the Friedmann equation\, which describes h
ow the scale factor of the Universe\, a(t) changes due to the physics and
composition of the Universe. Most of what we know about the Universe from
this route comes from measuring just the first two derivatives of a(t)\, p
arameters known as the Hubble constant (a dot) and the deceleration parame
ter (a double-dot). These quantities can be measured by estimating distanc
es to exploding and pulsating stars. In 1998\, two teams (including the Hi
gh-z Team and this author) used measurements of supernovae to show that th
e deceleration parameter was negative\, that is\, the expansion is now acc
elerating due to mysterious dark energy. Understanding the nature of dark
energy remains one of the biggest goals of modern physics. More recently\,
the author has been working to improve measurements of the other paramete
r\, the Hubble constant\, which measures the present expansion rate. The H
ubble constant remains one of the most important parameters in the cosmolo
gical model\, setting the size and age scales of the Universe. Present unc
ertainties in the cosmological model including the nature of dark energy\,
the properties of neutrinos and the scale of departures from flat geometr
y can be constrained by measurements of the Hubble constant made to higher
precision than was possible with the first generations of Hubble Telescop
e instruments. A streamlined distance ladder constructed from infrared obs
ervations of Cepheids and type Ia supernovae with ruthless attention paid
to systematics now provide by 10am on Thursday\, October 17th.

DESCRIPTION:Topic: 4D Scattering as 2D Correlators\n\nSpeaker: Sabrina Gonz
alez Pasterski\, Princeton University\n\nThe asymptotic symmetry algebra o
f asymptotically flat spacetimes implies an infinity of conserved charges
for 4D scattering which can be neatly recast as 2D conformal Ward identiti
es. We cover recent progress on the proposed 4D/2D dictionary starting fro
m the conformally soft modes that appear as currents and extending our map
to a basis for finite energy scattering states.

DESCRIPTION:Topic: Learning arithmetic circuits in the average case via low
er bounds\n\nSpeaker: Ankit Garg\, Microsoft Research\n\nVideo: https://vi
deo.ias.edu/csdm/2019/1021-AnkitGarg\n\nThe problem of learning arithmetic
circuits is the following: given a polynomial as a black box that is prom
ised to have a small arithmetic circuit computing it\, can we find this ar
ithmetic circuit? This problem is hard in the worst case and so previous w
orks have focused on regimes where the NP-hardness doesn’t kick in (e.g. c
onstant top fan-in etc.). We focus on the average case where one assumes c
ertain non-degeneracy assumptions on the circuit (formally these amount to
assuming the circuit parameters lie outside a certain variety and hence i
f they are chosen randomly according to any reasonable distribution\, the
non-degeneracy condition is satisfied whp). Kayal and Saha gave a meta fra
mework for designing these algorithms for circuit classes where we have lo
wer bounds. They carried this out for depth 3 circuits (sums of products o
f linear forms) and we (in joint work with Kayal and Saha) carry it out fo
r depth 4 powering circuits (sums of powers of low degree polynomials). I
will talk about the meta framework and then about our specific results. I
will also talk about a potential application to learning mixtures of gener
al Gaussians.

hift Sample for Galaxy Clustering Measurements with LSST\n\nSpeaker: Adam
Broussard\, Rutgers\, The State University of New Jersey\n\nThe Large Syno
ptic Survey Telescope (LSST) is projected to observe approximately 25 bill
ion galaxies\, which will be incredibly useful for measurements of galaxy
clustering and large scale structure in the Universe. One of the primary l
imiting factors in a galaxy clustering analysis\, however\, is the determi
nation of photometric redshifts for a large sample of these galaxies. Whil
e the longstanding expectation is that red sequence galaxies with a strong
Balmer/4000 Angstrom break have the spectral shape that provides the most
precise redshift fits\, we consider the alternative of galaxies that exhi
bit extreme emission lines (EELs). We find that EELs are numerous enough t
o beat the shot noise and are therefore a promising sample for LSS measure
ments.

To understand the behavior of solutions in these spaces\, the logarithmic

aces\, local well-posedness was proved Chae-Wu when the regularization is
sufficiently strong\, while strong ill-posedness of the unregularized case

DESCRIPTION:Topic: Towards a theory of non-commutative optimization: geodes
ic 1st and 2nd order methods for moment maps and polytopes\n\nSpeaker: Raf
ael Oliveira\, University of Toronto\n\nVideo: https://video.ias.edu/csdm/
2019/1022-RafaelOliveira\n\nScaling problems\, such as operator scaling an
d tensor scaling\, have recently found several applications in diverse are
as of math and CS. They have been used to give efficient algorithms for no
n-commutative rational identity testing\, compute the optimal constant in
Brascamp-Lieb inequalities\, one-body quantum marginal problem\, solution
to the Paulsen problem\, and the search version of the Horn's problem\, to
name a few\, [GGOW15\, GGOW18\, BFGOWW18\, KLLR18\, F18]. Scaling problem
s are natural geodesic convex optimization problems on Riemannian manifold
s that arise from the symmetries of non-commutative groups\, and the algor
ithms (and their analyses) developed in these previous works heavily relie
d on this general form of convexity. In this talk we discuss our recent sy
stematic development of a theory of non-commutative optimization\, which g
reatly extends ordinary (Euclidean) convex optimization. We will see how N
C optimization unify and generalize the algorithms developed for the unifo
rm and non-uniform versions of the operator scaling and tensor scaling pro
blems. More specifically\, our algorithms minimize the moment map (a non-c
ommutative notion of the usual gradient)\, and test membership in moment p
olytopes (a vast class of polytopes\, typically of exponential vertex and
facet complexity\, which quite magically arise from this a priori non-conv
ex\, non-linear setting). In the spirit of standard convex optimization\,
we develop two general methods in the geodesic setting\, a first order and
a second order method\, which respectively receive first and second order
information on the derivatives'' of the function to be optimized. We will
also show the key parameters of the underlying group actions which contro
l convergence to the optimum in each of these methods. The non-commutative
analogues of smoothness'' (from the commutative case) are far more comple
x\, and require significant algebraic and analytic machinery (much existin
g and some newly developed in this work). Despite this complexity\, we sha
ll see that the way in which these parameters control convergence in both
methods is quite simple and elegant. Based on joint work with Peter Buergi
sser\, Cole Franks\, Ankit Garg\, Michael Walter and Avi Wigderson.

ker: Emily Levesque\, University of Washington\n\nRed supergiants (RSGs) a
re the helium-fusing descendants of moderately massive (10-25Mo) stars. As
the coldest and largest (in physical size) members of the massive star po
pulation\, these evolved stars serve as ideal 'magnifying glasses' for scr
utinizing our current understanding of massive stars and their role as sup
ernova progenitors. RSGs are the observationally-confirmed progenitors of
Type II-P\, an intermediate evolutionary phase in the lifetimes of some st
ripped-envelope SN progenitors\, and a crucial step in the formation and p
opulation statistics of massive interacting binaries (including those that
will ultimately produce compact object binaries and gravitational waves).
This talk will provide an overview of our field's current knowledge of RS
Gs\, identify some of the most pressing open questions about these stars a

Gs in the coming decade as the next generation of observatories comes onli

DESCRIPTION:Topic: Cosmic Ray Transport and the Galaxy Gas Cycle\n\nSpeaker
: Chad Bustard\, University of Wisconsin-Madison\n\nDespite representing o
nly a billionth of the gas population\, cosmic rays have enough energy to
significantly shape the structure of the ISM\, the supernova-driven outflo
ws that emanate from it\, and the surrounding circumgalactic medium (CGM)\
, which contains a large fraction of the baryons in the galactic ecosystem
. They exert this influence\, however\, through micro-scale interactions w
ith plasma fluctuations on scales of order 1 AU. Fully realizing the macro
scopic\, observable effects of cosmic rays\, therefore\, requires a truly
cross-disciplinary effort between astronomy and plasma physics. I will pre
sent two recent projects in which I leverage novel numerical techniques an
d plasma physics-based cosmic ray treatments to simulate cosmic rays in ga
laxies. This talk will go from small-to-large scales\, building in complex
ity from intuition-building studies of the Parker instability (Heintz\, Bu
stard\, and Zweibel 2019) to the role of cosmic rays in the complicated en
vironment of the Magellanic System (Bustard+ 2019\, in prep). We find\, in
each study\, that cosmic rays shape their surroundings to promote a flux
of gas\, magnetic fields\, and cosmic rays from disks\, develop a cosmic r
ay dominated halo\, and significantly affect the gas phase structure in ha
los and the CGM. This cosmic ray impact on the galaxy gas cycle promises t
o narrow gaps between observed and simulated outflows\, with the Large Mag
ellanic Cloud being an intriguing\, nearby example. Future work to more th
oroughly characterize the cosmic ray flux out of the multiphase\, turbulen
t ISM is necessary.

DESCRIPTION:Topic: Galactic Archeology of the Brightest Cluster Galaxy M87
\n\nSpeaker: Alexa Villaume\, University of California\, Santa Cruz\n\nThe
galactocentric radial metallicity gradients of GC systems can be used to
probe the assembly histories of galaxies but doing so is complicated by: 1
.) a GC system is an aggregate population of several (or many) different s
ubpopulations of different origins\, and 2.) computing the gradients with
respect to projected galactocentric distances can artificially flatten the
gradient. I describe a hierarchical statistical framework measure the rad
ial metallically gradients of the GC subpopulations and its application th
e brightest cluster galaxy M87 using spectroscopically-derived metalliciti
es for a large sample of GCs. Contrary to much previous work I find that t
he metal-rich and metal-poor subpopulations have different gradients\, ind
icating they were affected by separate events. Moreover\, I find the gradi
ents change between the inner and outer halo\, indicating that M87 has at
least two merger events in its assembly history. I describe the results of
doing weak chemical tagging'' on physically-motivated spectral stacks of
the GC subpopulations and compare these results to the stellar parameters
derived spatially-resolved spectroscopy for the galaxy light of M87. I wil
l discuss these results in context of the formation and assembly history o
f M87 and assess how well predictions from cosmological galaxy formation s
imulations match our results.

DESCRIPTION:Topic: Interpreting the Kitchen Sink: a Path Towards Better Und
erstanding Galaxy Evolution\n\nSpeaker: John Forbes\, Center for Computati
onal Astrophysics\, Flatiron Institute\n\nGalaxy formation is a field curr
ently overwhelmed by data\, from large surveys to cosmological simulations
. As the simulations continue to improve their matches to the observations
\, some have been left wondering whether the basic picture of galaxy evolu
tion is settled. I will argue that this is far from the case\, and that a
sophisticated new generation of semi-analytic models and statistical techn
iques are needed to simultaneously address the strong degeneracies that pe
rsist in the problem of galaxy evolution and to coherently comprehend the
vast quantities of extant and forthcoming data.

DESCRIPTION:Topic: A slice or two of a diagonal cubic: arithmetic stratific
ation via the circle method\n\nSpeaker: Trevor Wooley\, Purdue University
\n\nVideo: https://video.ias.edu/puias/2019/1024-TrevorWooley\n\nSome 25 y
ears ago\, as announced at a previous version of this seminar\, Vaughan an
d the speaker obtained asymptotic upper and lower bounds for the number of
non-trivial integral points on the Segre cubic x31+...+x36=x1+...+x6=0x_1
^3+...+x_6^3=x_1+...+x_6=0 with naive height bounded by a large parameter
$B$. Seeking an explanation for the unexpected’’ growth rate $B^2(\log B)^
5$\, they offered a heuristic explanation for the role of the major and mi
nor arc contributions in the application of the circle method to this prob
lem\, and connected these terms with Manin’s ideas on arithmetic stratific
ation. We now consider diagonal cubics in more variables with one or two l
inear slices in the light of recent progress on Vinogradov’s mean value th
eorem. In particular\, in work joint with Joerg Bruedern\, we are able to
prove an asymptotic formula in which Manin’s arithmetic stratification ide
ntifies naturally and provably in terms of major and minor arc contributio
ns from the circle method.

Student\n\nAccurate understanding of astrophysical foregrounds is crucial
in recovering the underlying CMB signal. In this talk I will discuss the d

DESCRIPTION:Topic: Two-temperature\, Radiative GRMHD Simulations of Sgr A*
and M87\n\nSpeaker: Andrew Chael\, Princeton University\n\nThe Event Horiz
on Telescope (EHT) is a global VLBI array with a 25 microarcsecond resolut
ion\, fine enough to image the black hole “shadows” in Sgr A* and M87. The
ionized accretion flows around both the black holes in Sgr A* and M87 are
hot (T>10^11 K) and diffuse\, and thus expected to have an electron tempe
rature that is distinct from the ion temperature. Standard general relativ
istic magnetohydrodynamic (GRMHD) simulations of these systems only solve
for a single fluid temperature dominated by the ions\, making it difficult
to directly connect simulations to images from the EHT and multiwavelengt
h observations. We have implemented a method for evolving a two-temperatur
e electron-ion fluid in radiative GRMHD simulations implemented in the cod
e KORAL. I will discuss two sets of 3D\, two-temperature GRMHD simulations
I performed both for Sgr A* and M87\, their implications for EHT and mult
iwavelength observations\, and the prospects for connecting images of Sgr
A* and M87 to the underlying plasma processes that heat and accelerate ele
ctrons in accretion flows.

erhardt\, Member\, School of Natural Sciences\, IAS\n\nVideo: https://vide
o.ias.edu/HET/2019/1025-LorenzEberhardt\n\nRecently\, an exact AdS3/CFT2 d
uality was proposed. String theory on AdS3xS3xT4 with one unit of pure NS-
NS background flux was conjectured to be dual to the symmetric product orb
ifold of T4. This is established at the level of the full spectrum of the
CFT. In this talk I will report on the matching of sphere correlation func
tions. This involves crucially the so-called spectrally flowed representat
ions. The moduli space integral of n-point functions for n>3 is argued to
localise to a finite sum. I will also discuss the corresponding classical
solution of the SL(2\,R) WZW model and show that their on-shell action pre
cisely reproduce the correlation functions in the symmetric product orbifo
ld as calculated by path integral methods.

DESCRIPTION:Topic: Furstenberg sets in finite fields\n\nSpeaker: Zeev Dvir\
, Princeton University\n\nVideo: https://video.ias.edu/csdm/2019/1028-Zeev
Dvir\n\nA (k\,m)-Furstenberg set K in F^n\, where F is a finite field\, is
a set such that any k-dimensional subspace of F^n can be shifted so that
it intersects K in at least m points. Such sets generalize in a natural wa
y finite field Kakeya sets (in which k=1\, and m=|F|)\, whose study has re
sulted in many applications\, including in theoretical computer science. T
he main question is how small can such a set K be. While the polynomial me
thod gives a complete answer to this question when k=1 (i.e.\, when K inte
rsects lines in all directions)\, it fails completely for larger values of
k. Until recently\, the only bound for general k and m was given by Ellen
berg and Erman using scheme theoretic techniques. In this talk I will disc
uss a new result (joint with Manik Dhar and Ben Lund) that give improved (
and in some cases tight) upper bounds on the size of Furstenberg sets for
general k and m using completely elementary arguments.

ert\, University of Michigan\; Member\, School of Mathematics\n\nVideo: ht
tps://video.ias.edu/members/2019/1028-AnnaGilbert\n\nIn this talk\, I will
give two vignettes on the theme of sparse matrices in sparse analysis. Th
e first vignette covers work from compressive sensing in which we want to
design sparse matrices (i.e.\, matrices with few non-zero entries) that we
use to (linearly) sense or measure compressible signals. We also design a
lgorithms such that\, from these measurements and these matrices\, we can
efficiently recover a compressed\, or sparse\, representation of the sense
d data. I will discuss the role of expander graphs and error correcting co
des in these designs and applications to high throughput biological screen
s. The second vignette flips the theme\; suppose we are given a distance o
r similarity matrix for a data set that is corrupted in some fashion\, fin
d a sparse correction or repair to the distance matrix so as to ensure the
corrected distances come from a metric\; i.e.\, repair as few entries as
possible in the matrix so that we have a metric. I will discuss generaliza
tions to graph metrics\, applications to (and from) metric embeddings\, an
d algorithms for variations of this problem. I will also touch upon applic
ations in machine learning and bio-informatics.

DESCRIPTION:Topic: Solar Interiors\, Helioseismology and Neutrinos\n\nSpeak
er: Aldo Serenelli\, Institute of Space Sciences\n\nFor more than 20 years
helioseismology\, the study of solar oscillations\, has provided an exqui
site picture of the solar interior structure. However these oscillations\,
which are standing acoustic waves in the solar interior\, have diminishin
g amplitudes towards the deep interior and render a blurred picture of the
solar innermost core\, where most nuclear reactions take place and neutri
nos are produced. During the last decade\, after the discovery of neutrino
oscillations\, solar neutrino experiments such as SuperKamiokande\, SNO a
nd more recently Borexino have continued to develop and improve the accura
cy and precision of measurements solar neutrino fluxes. Helioseismic and n
eutrino constraints offer complementary views of solar interiors and open
up the best possibilities to date for testing solar (and stellar) evolutio
n theory as well as for using the Sun a laboratory for particle physics. T
he talk will first review the current status of (standard) solar modeling
in the context of helioseismic constraints\, and discuss where problems an
d uncertainties lie. About the latter\, some emphasis will be placed on re
cent calculations and experiments of radiative opacities that impact solar
and stellar modeling. The second part of the talk will present results of
solar neutrino experiments\, focusing on Borexino's capabilities to perfo
rm solar neutrino spectroscopy\, and the constraints on solar interior mod
els that can be obtained. The third part of the talk will briefly discuss
the relevance of solar model uncertainties for evolution of low mass stars
and the uncertainties in determination of stellar properties based on ast
eroseismic results might be affected.

DESCRIPTION:Topic: The Role of the Host Star in Shaping Planetary System Ar
chitectures\n\nSpeaker: Chris Spalding\, Yale University\n\nThe census of
extrasolar planets detected continues to grow well into the thousands. Thu
s set of exoplanetary systems have emerged as exhibiting large orbital mis
alignments with respect to both other planets in the system\, and with res
pect to the host star's spin axis. Moreover\, most planets detected reside
on orbits substantially closer to their host stars than Mercury sits to t
he Sun. In contrast\, our Solar system exhibits small inclinations and the
Sun's spin axis is relatively well-aligned. In this talk\, I explore the
hypothesis that the ultimate 3-dimensional architectures of planetary syst
ems is largely set by physical mechanisms playing out during the opening 1
0-100 million years of planetary system evolution. I will show how the ste
llar quadrupole moment of young stars may destabilize planetary systems\,
and how the young Solar wind can have played a role removing material from
the innermost Solar system. I discuss tests of these hypotheses promising
to emerge within upcoming datasets\, and important lessons that exoplanet
ary characterization has revealed about our own Solar system's history.

ematics\n\nVideo: https://video.ias.edu/members/2019/1104-SaraTukachinsky
\n\nOpen Gromov-Witten (OGW) invariants should count pseudoholomorphic map
s from curves with boundary to a symplectic manifold\, with various constr
aints on boundary and interior marked points. The presence of boundary pos
es an obstacle to invariance. In a joint work with J. Solomon (2016-2017)\
, we defined genus zero OGW invariants under cohomological conditions.The
construction is rather abstract. Nonetheless\, in a recent work\, also joi
nt with J. Solomon\, we find that the generating function of OGW has many
properties that enable explicit calculations. Most notably\, it satisfies
a system of PDE called open WDVV (Witten-Dijkgraaf-Verlinde-Verlinde) equa
tion. For the projective space\, this PDE generates recursion relations th
at allow the computation of all invariants. Moreover\, the open WDVV can b
e reinterpreted as an associativity of a suitable version of a quantum pro
duct. No prior knowledge of any of the above notions will be assumed.

DESCRIPTION:Topic: Chaotic and Thermodynamic Properties of two Coupled Sach
dev-Ye-Kitaev Models\n\nSpeaker: Jacobus Verbaarschot\, Stony Brook Univer
sity\n\nThe SYK Model was originally introduced as a random matrix model f
or the nuclear interaction that also describes the exponential rise of the
spectral density known as the Bethe formula. Exactly this behavior is the
hallmark of the Schwarzian action\, the low energy limit of the SYK model
\, which is the main reason for the excitement this model has brought to t
he field of Quantum Gravity. Another phenomenon in chaotic many-body quant
um systems is the existence of collective excitations. Remarkably\, they a
re present in the Maldacena-Qi model of two SYK models coupled by a spin-s
pin interaction\, which describes a phase transition between two black hol
es and a thermal phase. The collective state is the ground state which is
close to a Thermo-Field Double state. We find that for systems that can be
studied numerically\, the wave functions of the ground state show substan
tial deviations from the Thermo-Field Double state\, which suggests a non-
uniform convergence to this state in the limit of a large number of partic
les. The main topic of this talk is the discussion of the thermodynamical
and spectral properties of the Maldacena-Qi Model. We find a transition fr
om Poisson statistics in the tail of the the spectrum to RMT statistics at
higher energies\, when we separate the Hamiltonian according to the spin
mod 4 symmetry. We relate this order-chaos transition to the Hawking-Page
phase transition.

\n\nSpeaker: Catherine Cannizzo\, Simons Center for geometry and physics\n
\nWe will discuss work from https://arxiv.org/abs/1908.04227 on a homologi
cal mirror symmetry result for a complex genus 2 curve. We will first note
how the result fits into the broader framework of HMS examples. Then we w
ill describe the geometric construction of the mirror. Finally we will see
the algebraic result on homogenous coordinate rings\, i.e. the HMS result
on the level of cohomology. The method involves first considering mirror
symmetry for the 4-torus\, then extending to a correspondence between a hy
persurface genus 2 curve and a mirror Landau-Ginzburg model with fiber the
mirror 4-torus. This is work from my thesis under my advisor Professor De
nis Auroux.

DESCRIPTION:Topic: Discovery Frontiers in the New Era of Time Domain Multi-
Messenger Astrophysics\n\nSpeaker: Raffaella Margutti\, Northwestern Unive
rsity\n\nNew and improved observational facilities are sampling the night
sky with unprecedented temporal cadence and sensitivity across the electro
magnetic spectrum. This exercise led to the discovery of new types of astr
onomical transients and revolutionized our understanding of phenomena that
we thought we already knew.In this talk I will review some very recent de
velopments in the field that resulted from the capability to acquire a tru
e panchromatic view of the most extreme stellar deaths in nature\, includi
ng the new class of fast and blue optical transients and extreme episodes
of mass-loss in the years leading up to stellar death.

DESCRIPTION:Topic: Born-Infeld Electrodynamics at One-Loop\n\nSpeaker: Call
um Jones\, University of Michigan\n\nThe Born-Infeld model is an effective
field theory of central importance describing the low-energy dynamics of
massless gauge bosons on the world-volume of D-branes. Though it is in man
y ways an exceptional model of nonlinear electrodynamics\, several aspects
of the physics of the Born-Infeld model remain mysterious. In this talk I
will explain how aspects of the model\, obscured in the traditional formu
lation of Lagrangian field theory\, are clarified by directly studying the
on-shell S-matrix. In particular in 3+1-dimensions\, classical Born-Infel
d has an electromagnetic duality symmetry which manifests in tree-level sc
attering amplitudes as the conservation of a chiral charge. Whether this c
onservation law can be preserved under perturbative quantization is presen
tly unknown. Using modern scattering amplitudes techniques\, we have initi
ated a study of the S-matrix of Born-Infeld at one-loop. I will describe h
ow generalized unitarity together with supersymmetric decomposition can be
used to explicitly calculate infinite classes of one-loop amplitudes\, an
d explain how the results are consistent with the existence of a quantum e
lectromagnetic duality.

DESCRIPTION:Topic: The Giant Molecular Cloud Lifecycle Under the Influence
of Galactic Dynamics\n\nSpeaker: Sarah Jeffreson\, International Max Planc
k Research School for Astronomy & Cosmic Physics at the University of Heid
elberg\n\nThe giant molecular cloud (GMC) lifetime places an upper bound o
n the local time-scale for star-formation\, linking cloud- and sub cloud-s
cale physics to galaxy-scale trends in the star formation rate. Recent obs
ervations reveal environmentally-driven trends in GMC properties (e.g. sur
face densities\, velocity dispersions\, and turbulent pressures)\, demandi
ng a systematic\, predictive theory of the GMC lifecycle across the parame
ter space of observable star-forming environments. I will present an analy
tic theory for GMC lifetimes set by the galactic-dynamical time-scales of
the interstellar medium\, dependent on just three sets of observables: the
rotation curve\, surface densities and velocity dispersions of the host g
alaxy. I will compare and contrast these predictions with a statistical sa
mple of simulated GMCs across three isolated disc galaxies\, modelled usin
g the hydrodynamical\, moving-mesh code Arepo. My simulations incorporate
the features required to accurately model star formation and the influence
of stellar feedback on the ISM\, including ISM chemistry\, a stochastic t
reatment of star formation\, mechanical supernova feedback\, and pre-super
nova feedback from HII regions. As such\, I will (1) examine the nature of
the relationship between key GMC properties and the galactic-dynamic envi
ronment\, and (2) investigate the influence of star formation feedback in
truncating the GMC lifetime\, relative to the dynamical prediction of the
analytic theory. I will also present a comparison of my theoretical result
s to pioneering observational data currently obtained with ALMA. Together\
, this combination of analytic\, numerical and observational results show
that the galactic dynamic environment plays a crucial role in determining
GMC lifecycles and thus the star formation rates of their host galaxies.

the 1960's\, Burgess proved a subconvexity bound for Dirichlet L-functions
. However\, the quality of this bound was not as strong\, in terms of the
conductor\, as the classical Weyl bound for the Riemann zeta function. In
a major breakthrough\, Conrey and Iwaniec established the Weyl bound for q
uadratic Dirichlet L-functions. I will discuss recent work with Ian Petrow
that generalizes the Conrey-Iwaniec bound for arbitrary Dirichlet charact

hundreds of billions the size of their launching region near the black hol
e. Using GRMHD simulations\, I will show how a jet\, collimated by its sur
roundings\, accelerates (and decelerates) for over five orders of magnitud
e in distance while exhibiting flow instabilities\, with significant conse
quences for the jet morphology. Closer to the black hole\, the complexity
of possible misalignment between the accretion disk and the black hole spi
n direction also brings about interesting morphological changes in the jet
\, with exciting implications for the Event Horizon Telescope black hole i
mages of the galaxy M87 as well as for our Galactic center.

DESCRIPTION:Topic: From Symmetries to Cosmological Observables: New Soft Th
eorems for Cosmological Correlators\n\nSpeaker: Luca Santoni\, Columbia Un
iversity\n\nTests based on model-independent predictions and non-perturbat
ive results relying on symmetries\, that go beyond explicit realizations o
f inflation and the linear or quasi-linear regime of perturbation theory\,
are of particular relevance in cosmology. One major example is given by c
onsistency conditions for cosmological correlators. Solely based on the sp
ontaneous breaking of non-linearly realized symmetries\, they are Ward ide
ntities connecting a squeezed (N+1)-point correlation function\, where one
of the momenta is taken to be ‘soft’\, to an N-point function. One notabl
e feature is that of being model-independent and non-perturbative. Further
more\, they are particularly useful from an experimental point of view bec
ause they constrain the observables directly and provide a direct connecti
on between the theory and the data. During the talk\, I will show how to g
eneralize the construction of the Weinberg’s adiabatic modes and the stand
ard consistency conditions for cosmological correlators to situations wher
e extra symmetries (in particular\, a shift symmetry) or additional fields
are at play in the early Universe\, and I will discuss possible interesti
ng implications at both theoretical and observational level.Organizers are
Jo Dunkley\, Princeton University\, and Matias Zaldarriaga\, Institute fo
r Advanced Study. The lunch will be held either at Princeton University or
the Institute for Advanced Study. Check the calendar for the meeting loca
tion. This week's meeting is at Princeton University. Attendees can bring
lunch.

DESCRIPTION:Topic: Testing Gravity with Cosmology: Efficient Simulations\,
Novel Statistics and Analytical Approaches\n\nSpeaker: Georgios Valogianni
s\, Cornell University\n\nIn the era of precision cosmology\, a wide range
of cosmological surveys\, such as the LSST\, DESI\, Euclid and WFIRST wil
l precisely probe the large-scale structure of the universe\, shedding lig
ht on the nature of the dark sectors. This will be an unprecedented opport
unity to constrain theoretical alternatives to dark energy\, such as model
s that consider modifications to general relativity. In order to fully uti
lize the wealth of incoming data\, however\, theoretical predictions of st
ructure formation in such alternative scenarios are necessary\, proven to
be particularly challenging to obtain\, due to the increased phenomenologi
cal complexity that is introduced. In this talk I will show how these chal
lenges can be overcome\, employing a combination of analytical perturbativ
e techniques\, hybrid N-body simulations and novel statistics\, that will
allow efficient and robust predictions of potential deviations from ΛCDM\,
which will confront the next stage of cosmological observations.

DESCRIPTION:Topic: S-matrix Bootstrap for Effective Field Theories\n\nSpeak
er: Joao Penedones\, École polytechnique fédérale de Lausanne\n\nI will ex
plain how the S-matrix Bootstrap for massless particles can be used to con
strain the space of Effective Field Theories (EFT). In particular\, I will
discuss the S-matrix bootstrap for massless particles in unitary\, relati
vistic two dimensional quantum field theories. In the context of flux tube
physics\, this allows us to constrain several terms in the S-matrix low e
nergy expansion or -- equivalently -- on Wilson coefficients of several ir
relevant operators showing up in the flux tube effective action. The S-mat
rices living at the boundary of the allowed space exhibit an intricate pat
tern of resonances with one sharper resonance whose quantum numbers\, mass
and width are precisely those of the world-sheet axion previously propose
d. Finally\, I will present work in progress on pion scattering amplitudes
and the chiral Lagrangian. The general method should be extendable to oth
er massless S-matrices including gauge and gravity theories.

\nSpeaker: Mike Usher\, University of Georgia\n\nVideo: https://video.ias.
edu/sympdynageo/2019/1111-MikeUsher\n\nI will explain how coisotropic subm
anifolds of symplectic manifolds can be distinguished among all submanifol
ds by a criterion ('local rigidity') related to the Hofer energy necessary
to disjoin open sets from them. This criterion is invariant under symplec
tic homeomorphisms\, leading to a simplified proof of the Humiliere-Lecler
cq-Seyfaddini theorem that a symplectic-homeomorphic image of a coisotropi
c submanifold that is smooth is coisotropic. Moreover much of this picture
extends to the contact context\, allowing one to extend the class of C^0-
limits of contactomorphisms which are known to map Legendrian submanifolds
to Legendrian submanifolds.

\n\nVideo: https://video.ias.edu/analysis/2019/1111-ThomasLeblé\n\nThe pat
h between two measures in the sense of optimal transport yields the notion
of *displacement interpolation*. As observed by R. McCann\, certain funct
ionals that are not convex in the usual sense are nonetheless *displacemen
t convex*. Following an idea of A. Guionnet\, we define a notion of displa
cement convexity at the level of point processes seen as measures on \R^{\
Z}\, and use it to prove that a certain free energy functional\, arising i
n Hermitian random matrix theory has a unique minimiser. This tells us som
ething about certain systems of particles in 1d. Joint work with M. Erbar

elescope at radio frequencies 400-800 MHz. The mapping speed (or total sta

DESCRIPTION:Topic: Fast IRLS Algorithms for p-norm regression\n\nSpeaker: S
ushant Sachdeva\, University of Toronto\; Member\, School of Mathematics\n
\nVideo: https://video.ias.edu/machinelearning/2019/1112-SushantSachdeva\n
\nLinear regression in L_p-norm is a canonical optimization problem that a
rises in several applications\, including sparse recovery\, semi-supervise
d learning\, and signal processing. Standard linear regression corresponds
to p=2\, and p=1 or infinity is equivalent to linear programming. Generic
convex optimization algorithms for solving p-regression are slow in pract
ice. Iteratively Reweighted Least Squares (IRLS) is an easy to implement f
amily of algorithms for solving these problems that has been studied for o
ver 50 years. However\, these algorithms often diverge for p > 3\, and sin
ce the work of Osborne (1985)\, it has been an open problem whether there
is an IRLS algorithm that is guaranteed to converge rapidly for p > 3. We
propose p-IRLS\, the first IRLS algorithm that provably converges geometri
cally for any p in [2\, infty). Our algorithm is simple to implement and i
s guaranteed to find a high accuracy solution in a sub-linear number of it
erations (roughly sqrt(dimension)*log 1/error). Our experiments demonstrat
e that it performs even better than our theoretical bounds\, beats the sta
ndard Matlab/CVX implementation for solving these problems by 10–50x\, and
is the fastest among available implementations in the high-accuracy regim
e.

DESCRIPTION:Topic: Numerical Modeling of Star Formation and Feedback in Nuc
lear Rings\n\nSpeaker: Sanghyuk Moon\, Seoul National University\n\nNuclea
r rings are compact ring-like structures often found in central regions of
disk galaxies. They are known to be present in 20% of nearby disk galaxie
s\, among which 80% are barred. Nuclear rings in strongly barred galaxies
are most likely to be formed by rapid gas infall due to gravitational torq
ue. Considering the fact that the gas is trapped in the nuclear ring and t
urns into stars\, it is important to understand how fast can star formatio
n take place in nuclear rings and how the star formation rate is related t
o the inflow rate\, in order to get a multi-scale view of the black hole f
eeding process. Star formation in nuclear rings deserves attention on its
own. The typical star formation rate is on the order of one solar mass per
year\, which sometimes comparable to the star formation rate of an entire
galaxy. The high star formation rate and the compactness of nuclear rings
imply that they are potential sites of pseudobulge formation. At the extr
emities\, they may be able to drive massive outflows energized by supernov
ae\, producing galactic winds that we see today in M82\, for example. Desp
ite an importance of star formation and feedback occurring in nuclear ring
s\, detailed investigation has been challenging in both observation and si
mulation\, partly because of its compactness\, which requires high observa
tional and/or numerical resolution. To understand how star formation proce
eds and how feedback regulates star formation in nuclear ring environment\
, we have built a numerical testbed especially tailored for nuclear rings.
In contrast to global galaxy-scale simulations\, our model enables well-c
ontrolled experiments to be performed with high resolution\, by modeling t
he bar-driven mass inflow as an input while concentrating only on the nucl
ear ring region. In this talk\, I will introduce nuclear rings in a contex
t of large-scale fueling process\, underlining an importance of understand
ing star formation therein. After describing our model and numerical metho
ds\, I will present outcomes of our numerical experiments and discuss the
implications\, limitations\, and future directions.

DESCRIPTION:Topic: Star Cluster Populations: The Link Between Star Formatio
n and Galaxy Formation\n\nSpeaker: Michael Fall\, Space Telescope Science
Institute\n\nThis talk presents a general picture of star cluster populati
ons\, from their formation in the clumpy ISM to their eventual dissolution
in the smooth stellar field. The picture is general or unified in the sen
se that it encompasses most traditional categories of star clusters: assoc
iations\, open clusters\, populous clusters\, globular clusters\, etc. The
key element of this picture is the mass function of clusters (spectrum of
cluster masses) and its time (age) dependence\, or equivalently\, the joi
nt distribution of masses and ages. HST observations have revealed some re
markable similarities in the mass-age distribution of clusters in differen
t galaxies\, analogous to similarities in the stellar mass function (IMF).
This talk presents physical explanations for these observations.

DESCRIPTION:Topic: Diffuse Galaxies As a Probe for Dark Matter\n\nSpeaker:
Shany Danieli\, Yale University\n\nLow mass galaxies provide an essential
testing ground for theoretical predictions of cosmology. They dominate the
counts in the Local Group and have high mass-to-light ratios\, making the
m ideal for studying dark matter on small scales. Recent advances in teles
cope instrumentation have opened a new window into the population of such
low surface brightness galaxies. In this talk\, I will present recent resu
lts from the Dragonfly Telescope\, which has identified large numbers of l
ow surface brightness galaxies beyond the Local Group and discuss its cont
ribution and potential in extending our ability to test LCDM on small scal
es. I will discuss the recently identified population of ultra-diffuse gal
axies (UDGs) that holds the promise of new constraints on low mass galaxie
s dynamics\, as their spatial extent and often significant globular cluste
r populations provide probes on spatial scales where dark matter should do
minate the kinematics. I will also discuss the dynamics of two UDGs that s
eems to lack most\, if not all\, of their dark matter. I will finish by pr
esenting our strategy for finding low surface brightness galaxies as part
of the recently completed Dragonfly Wide Field Survey\, covering 330 sq. d
eg.\, in the GAMA and Stripe 82 fields.

DESCRIPTION:Topic: Local systems over Shimura varieties: a comparison of tw
o constructions\n\nSpeaker: Kai-Wen Lan\, University of Minnesota\n\nGiven
a Shimura variety\, we can construct two kinds of automorphic local syste
ms\, i.e.\, local systems attached to algebraic representations of certain
associated algebraic group. The first is based on the classical complex a
nalytic construction using double quotients\, while the second is a p-adic
analytic construction based on some recently developed p-adic analogue of
the Riemann-Hilbert correspondence. I will explain how to compare these t
wo constructions even when the Shimura variety is not of abelian type\, an
d mention some applications and recent developments. (This is based on joi
nt work with Hansheng Diao\, Ruochuan Liu\, and Xinwen Zhu.)

DESCRIPTION:Topic: An Independent Determination of the Hubble Constant Base
d on the Tip of the Red Giant Branch\n\nSpeaker: Rachael Beaton\, Princeto
n University\n\nThe value of the Hubble constant (H0) continues to be an a
ctive topic in observational astronomy and many teams are now presenting r
esults at comparable precision. Taken together\, there is evidence for a s
ystematic discrepancy between these local measurements and measurements ti
ed to the Cosmic Microwave Background. I will describe\, in detail\, the k
ey results from the Carnegie-Chicago Hubble Program (CCHP) that has produc
ed a calibration of the supernovae Ia using the Tip of the Red Giant Branc
h (TRGB) as a cross-check on Cepheid-based distances. Our first H0 measure
ment was published in [Freedman et al. 2019](https://arxiv.org/abs/1907.05
922)\, with two accompanying papers -- [Hoyt et al. 2019](https://arxiv.or
g/abs/1907.05891) and [Beaton et al. 2019](https://arxiv.org/abs/1908.0612
0) -- that continued to refine systematic and statistical uncertainties af
filiated with the TRGB measurements. Our H0 measurement is in statistical
agreement (Yuan et al. 2019 and [Reid\, Pesce\, and Riess 2019](https://ar
xiv.org/abs/1908.05625)). Originally the CCHP proposed to avoid the Large
Magellanic Cloud\, due to the complexities of measurement therein\, but I
will describe the struggle to use other calibration paths due to systemati
c uncertainties in Gaia DR2 ([Neeley et al. 2019](https://arxiv.org/abs/19
10.01773)). I will counter the concerns raised in Yuan et al. with a discu
ssion of systematics induced from stellar population variance and from nua
nces in photometric measurements that\, when taken into account\, bring ou
r apparently disparate measurements into accord. I conclude with why movin
g into the infrared\, where the impact of dust is reduced\, is the best op
tion\, but list the current instrumentation challenges we face toward real
izing that goal.

DESCRIPTION:Topic: Can learning theory resist deep learning?\n\nSpeaker: Fr
ancis Bach\, INRIA\n\nMachine learning algorithms are ubiquitous in most s
cientific\, industrial and personal domains\, with many successful applica
tions. As a scientific field\, machine learning has always been characteri
zed by the constant exchanges between theory and practice\, with a stream
of algorithms that exhibit both good empirical performance on real-world p
roblems and some form of theoretical guarantees. Many of the recent and we
ll publicized applications come from deep learning\, where these exchanges
are harder to make\, in part because the objective functions used to trai
n neural networks are not convex. In this talk\, I will present recent res
ults on the global convergence of gradient descent for some specific non-c
onvex optimization problems\, illustrating these difficulties and the asso
ciated pitfalls (joint work with Lénaïc Chizat and Edouard Oyallon).

DESCRIPTION:Topic: Extreme eigenvalue distributions of sparse random graphs
\n\nSpeaker: Jiaoyang Huang\, Member\, School of Mathematics\n\nVideo: htt
ps://video.ias.edu/analysis/2019/1115-JiaoyangHuang\n\nI will discuss the
extreme eigenvalue distributions of adjacency matrices of sparse random gr
aphs\, in particular the Erd{\H o}s-R{\'e}nyi graphs $G(N\,p)$ and the ran
dom $d$-regular graphs. For Erd{\H o}s-R{\'e}nyi graphs\, there is a cross
over in the behavior of the extreme eigenvalues. When the average degree $
Np$ is much larger than $N^{1/3}$\, the extreme eigenvalues have asymptoti
cally Tracy-Widom fluctuations\, the same as Gaussian orthogonal ensemble.
However\, when $N^{2/9}\ll Np\ll N^{1/3}$ the extreme eigenvalues have as
ymptotically Gaussian fluctuations. The extreme eigenvalues of random $d$-
regular graphs are more rigid\, we prove on the regime $N^{2/9}\ll d\ll N^
{1/3}$ the extremal eigenvalues are concentrated at scale $N^{-2/3}$ and t
heir fluctuations are governed by the Tracy-Widom statistics. Thus\, in th
e same regime of $d$\, $52\%$ of all $d$-regular graphs have the second-la
rgest eigenvalue strictly less than $2\sqrt{d-1}$. These are based on join
t works with Roland Bauerschmidt\, Antti Knowles\, Benjamin Landon and Hor
ng-Tzer Yau.

DESCRIPTION:Topic: The ALMA View of Planet Formation\n\nSpeaker: Jane Huang
\, Harvard University\n\nThe ubiquity and diversity of exoplanets tell us
that planets can emerge under an astonishing range of conditions. Observat
ions of protoplanetary disks yield insights into how the masses\, composit
ions\, and orbital architectures of planets are influenced by their natal
environments. While protoplanets are difficult to detect directly\, the ad
vent of high-resolution\, high-sensitivity telescope facilities such as AL
MA has now made it possible to search systematically for disk structures p
otentially induced by planet-disk interactions and use their morphologies
to infer characteristics of the young planet population. We recently under
took the first high angular resolution ALMA survey of protoplanetary disks
\, the Disk Substructures at High Angular Resolution Program (DSHARP). Con
centric rings and gaps are the most common type of substructure observed i
n dust continuum emission and are found in disks spanning a large range of
ages and stellar host spectral types. The widespread presence of these st
ructures suggests that giant planet formation may occur readily within a m
illion years throughout much of the extent of the disk. Spiral arms are se
en in a minority of disks and may arise either because of perturbations fr
om an unseen wide-orbit companion or from gravitational instabilities. Fin
ally\, while recent planet formation modeling efforts have primarily focus
ed on interpreting dust observations\, I will discuss case studies of how
molecular line observations can uniquely provide key tests of planet forma
tion theories.

DESCRIPTION:Topic: Attractors\, Bifurcations and Curvature in Multi-Field i
nflation\n\nSpeaker: Evangelos Sfakianakis\, Nikhef and Leiden University
\n\nRecent years have seen the introduction of various multi-field inflati
onary scenarios\, in which the curvature and geodesics of the scalar manif
old play a crucial role. I will outline a simple description that unifies
these different proposals and discuss their stability criteria. I will dem
onstrate how the underlying dynamics is governed by an effective potential
\, whose critical points and bifurcations determine the late-time behavior
of the system\, thus unifying hyperinflation\, angular\, orbital and side
-tracked inflation. Interestingly\, hyperinflation can be shown to be a sp
ecial case of side-tracked inflation. This equivalence relies on the enhan
ced isometries of the hyperbolic manifold and I will show the explicit coo
rdinate transformation that maps the two models into each other. In the ca
se of angular inflation\, the universal predictions of multi-field alpha a
ttractors are modified\, allowing us to constrain the curvature of the hyp
erbolic manifold and mass ratio of the two fields\, for certain models.

ute of Science\; Visiting Professor\, School of Mathematics\n\nVideo: http
s://video.ias.edu/HermannWeyl/2019/1118-IritDinur\n\nThe PCP theorem says
that any mathematical proof can be written in a special 'PCP' format such
that it can be verified\, with arbitrarily high probability\, by sampling
only a few symbols in the proof. Hence the name\, Probabilistically Checka
ble Proofs (PCPs). Alternatively and equivalently\, any system of multivar
iate polynomial equations can be efficiently converted into another\, so t
hat if no input satisfies all equations in the former\, no input satisfies
even a tiny fraction of the equations in the later. Moreover\, each of th
e new equations will involve only 3 variables. This theorem is the key to
understanding the difficulty of approximation and optimization problems\;
and also amazingly finds uses in modern cloud computing protocols. We will
explain the context and meaning of the theorem\, and outline a proof that
relies on expander graphs\, which are a central combinatorial object in n
umerous computer science and mathematical areas.

Institute\n\nI will describe my work\, all joint with D. Gaiotto and some
also joint with E. Witten\, to understand the homotopy type of the space o
f (1+1)d N=(0\,1) SQFTs --- what a condensed matter theorist would call 'p
hases' of SQFTs. Our motivating hypothesis (due in large part to Stolz and
Teichner) is that this space models the spectrum called 'topological modu
lar forms'. Our work includes many nontrivial checks of this hypothesis. F
irst\, the hypothesis implies constraints on the possible values of ellipt
ic genera\, and suggests (but does not imply) the existence of holomorphic
SCFTs saturating these constraints\; we have succeeded in constructing su
ch SCFTs in low central charge. Second\, the hypothesis implies the existe
nce of torsion-valued 'secondary invariants' beyond the elliptic genus tha
t protect SQFTs from admitting deformations that spontaneously break super
symmetry. I will explain such an invariant in terms of holomorphic anomali
es and mock modularity.

report on a joint work with M. Abouzaid\, S. Guillermou and T. Kragh. The
nearby Lagrangian conjecture predicts that a closed exact Lagrangian subm
anifold in a cotangent bundle must be Hamiltonian isotopic to the zero-sec
tion. In particular the stable Gauss map of such a Lagrangian should be nu
ll-homotopic. I will explain a proof of the weaker statement that the stab
le Gauss map vanishes on all homotopy groups. The key concept that we intr
oduce is the notion of twisted generating function designed to describe La
grangians with a priori non trivial Gauss map. We also rely on deep result
s of pseudo-isotopy theory due to M. Bökstedt.

\n\nVideo: https://video.ias.edu/csdm/2019/1119-FotiosIlliopoulos\n\nThe t
asks of finding and randomly sampling solutions of constraint satisfaction
problems over discrete variable sets arise naturally in a wide variety of
areas\, among them artificial intelligence\, bioinformatics and combinato
rics\, and further have deep connections to statistical physics.\n\nIn thi
s first talk of the series\, I'll cover some recent results regarding algo
rithms for finding and sampling solutions of constraint satisfaction probl
ems\, which are inspired by the Lovasz Local Lemma. The latter is a powerf
ul tool in probabilistic combinatorics\, guaranteeing the existence of con
figurations that avoid a collection of 'bad' events that are mostly indepe
ndent and have low probability.

DESCRIPTION:Topic: Generation I Planets\n\nSpeaker: Yanqin Wu\, University
of Toronto\n\nA large number of close-in super-Earths have now been discov
ered. These planets are most likely formed while the proto-planetary disks
are still alive\, hence the title of this talk. I will report some recent
observational results\, regarding their masses\, compositions\, relations
hip to companion planets\, and to host star metallicity and binarity. A pi
cture emerges where gen-I planets share surprisingly uniform properties. E
arth and other terrestrial planets probably formed after the gaseous disks
have dispersed (gen-II planets). Currently we have scant evidence for the
ir existence in extra-solar systems. This strongly motivates new searches.

\nSpeaker: Irit Dinur\, Weizmann Institute of Science\; Visiting Professor

1119-IritDinur\n\nHigh dimensional expansion generalizes edge and spectral
expansion in graphs to higher dimensional hypergraphs or simplicial compl
exes. Unlike for graphs\, it is exceptionally rare for a high dimensional
complex to be both sparse and expanding. The only known such expanders are
number-theoretic or group-theoretic.Their key feature is a local-to-globa
l geometry\, that allows deducing global information about the entire comp
lex from local information in the neighborhoods / links. We will discuss s
ome results known about these objects\, and how their local-to-global geom
etry\, shared also by PCPs\, can potentially lead to new codes and proofs.

DESCRIPTION:Topic: From Superbubbles to the Circumgalactic Medium\; How Mul
tiphase Mixing Regulates Galaxy Formation\n\nSpeaker: Drummond Fielding\,
Simons Foundation\n\nThe flow of gas into and out of galaxies regulates th
eir evolution over cosmic time. The dynamics of these multiphase flows are
sensitive to the small scale processes that mediate the mixing of the hot
and cold phases. I will highlight two examples where this is mixing is ac
utely important: (i) the launching of galactic winds by supernova powered
superbubbles\, and (ii) the balance of turbulent heating and radiative coo
ling that determines galactic accretion. Then\, based on a suite of high r
esolution simulations\, I will present a new model based on the fractal na
ture of radiative turbulent mixing layers that fully characterizes the phy
sical processes that control the multiphase mixing.

DESCRIPTION:Topic: Integrable Deformations in Quantum Mechanics\, T-Tbar\,
and SYK\n\nSpeaker: Edgar Shaghoulian\, Cornell University\n\nThe Wilsonia
n paradigm suggests universality of quantum field theory in the infrared.
Interestingly\, it also suggests universality of quantum mechanics (d=1 qu
antum field theory) in the ultraviolet. This suggests a study of the lands
cape of the infrared and the robustness of the ultraviolet. I will introdu
ce and solve an infinite class of integrable deformations to quantum mecha
nics\, focusing on a particular deformation inspired by the T-Tbar deforma
tion of two-dimensional quantum field theory. In the context of holography
\, I will show how these deformations modify Jackiw-Teitelboim gravity in
AdS_2. I will also present an equivalent description of the T-Tbar deforma
tion in terms of coupling to worldline gravity. Applications to the Schwar
zian theory and SYK will be discussed.

Member\, School of Mathematics\n\nA main theme in extremal combinatorics i
s about asking when the random construction is close to optimal. A famous
conjecture of Erd\H{o}s-Simonovits and Sidorenko states that if $H$ is a b
ipartite graph\, then the random graph with edge density $p$ has in expect
ation asymptotically the minimum number of copies of $H$ over all graphs o
f the same number of vertices and edge density. It turns out it is quite d

fields such as random matrix theory. I will discuss some tools used to ad

DESCRIPTION:Topic: Time-domain & Muli-messenger Astrophysics in the Era of
Big Data\n\nSpeaker: Ashley Villar\, Harvard-Smithsonian Center for Astrop
hysics\n\nThe Large Synoptic Survey Telescope (LSST) will begin science op
erations in 2022 and is expected to increase the discovery rate of extraga
lactic transients by two orders of magnitude. With this transition comes t
he important question: how do we classify these events and separate the in
teresting “needles” from the “haystack” of objects? While it’s necessary t
o pick out these needles\, it is equally important to understand the hayst
ack — or the millions of events which lack any multi wavelength or spectro
scopic followup. In this talk\, I will discuss ongoing efforts to classify
/characterize the future haystack and to understand one particularly excit
ing type of needle: kilonovae. In particular\, I will introduce two method
s to classify supernovae based on their optical light curves\, which have
been trained and tested on data from the Pan-STARRS Medium Deep Survey. Th
e first method combines Bayesian model fitting with a variety of supervise
d classification methods\, while the second method uses a semi-supervised
recurrent neural network-based autoencoder. I will then discuss how well w
e can extract physical insights from LSST-like light curves without additi
onal followup. I will focus on the rare classes of Type I superluminous su
pernovae and kilonovae as case studies. I will show how target-of-opportun

.

DESCRIPTION:Topic: The Black Hole-jet Connection in M87: Linking simulation
s to VLBI images\n\nSpeaker: Andrew Chael\, Princeton Center for Theoretic
al Physics (PCTS)\n\nThe Event Horizon Telescope (EHT) has produced the fi
rst image of the 1.3 mm-wavelength emission around the black hole 'shadow'
at the heart of M87. The hot plasma in the accretion flow around M87's ce
ntral black hole illuminates the spacetime\, and the flow's magnetic field
extracts energy from the black hole to launch the famous relativistic jet
which is prominent in VLBI images at longer wavelengths. General relativi
stic magnetohydrodynamic (GRMHD) simulations are a powerful tool for study
ing the accretion flow and jet in M87. I will discuss the library of these
simulations used by the EHT collaboration to constrain the properties of
the black hole and emitting plasma in M87. I will also describe new simula
tions of M87 which go beyond single-fluid MHD to evolve separate electron
and ion populations\, as these species are likely not in equilibrium in ho
t accretion flows. These simulations can connect EHT images of the shadow
at 1.3 mm to the relativistic jet at longer wavelengths to constrain the p
hysics of the jet launching region\, and indicate the powerful\, wide-open
ing-angle jet in M87 is naturally launched by a magnetically arrested accr
etion flow.Should you wish to order lunch\, you may do so here https://for

ven a D-left regular bipartite graph G = ([n]\, [m]\, E) and a 'small' cod
e C \in {0\,1}^D\, the Tanner construction shows how to lift this code to
a 'large' code on n- bits. These Tanner lifts are extremely useful. For in
stance\, if C is a 'small' code with good distance and rate and G is a bip
artite expander\, then the Sipser-Spielman analysis shows that the lifted
code is a 'large' code that has good distance and rate. We will show a sim
ilar lifting property for local-testability. More precisely\, let C_0 be a
small code such that its lift C (defined via a bipartite graph) has non-t
rivial rate. We will show that if the bipartite-graph is part of a HDX and
a small-lift is testable\, then so is the large-lift C.

DESCRIPTION:Topic: Soft Theorems in the Sky\, Constraints on Correlators fr
om Symmetries\n\nSpeaker: Sam Wong\, University of Pennsylvania\n\nWe cons
ider the most general implication of non-linearly realized symmetries in c
osmology for correlation functions\, which is a set of soft theorems analo
gous to that in scattering amplitude. We introduce the physical mode condi
tion in order for the soft theorems to apply to equal time correlation fun
ctions. A new set of identities is derived for scenarios with massive part
icles during slow roll inflation and they can be employed to constraint co
rrelation functions. We also discuss implications for large scale structur
e.Organizers are Jo Dunkley\, Princeton University\, and Matias Zaldarriag
a\, Institute for Advanced Study. The lunch will be held either at Princet
on University or the Institute for Advanced Study. Check the calendar for

DESCRIPTION:Topic: Convergence of nearest neighbor classification\n\nSpeake
r: Sanjoy Dasgupta\, University of California\, San Diego\; Member\, Schoo
l of Mathematics\n\nVideo: https://video.ias.edu/members/2019/1125-SanjoyD
asgupta\n\nThe 'nearest neighbor (NN) classifier' labels a new data instan
ce by taking a majority vote over the k most similar instances seen in the
past. With an appropriate setting of k\, it is capable of modeling arbitr
ary decision rules. Traditional convergence analysis for nearest neighbor\
, as well as other nonparametric estimators\, has focused on two questions
: (1) universal consistency---that is\, convergence (as the number of data
points goes to infinity) to the best-possible classifier without any cond
itions on the data-generating distribution---and (2) rates of convergence
that are minimax-optimal\, assuming that data distribution lies within som
e standard class of smooth functions. We advance what is known on both the
se fronts. But we also show how to attain significantly stronger types of
results: (3) rates of convergence that are accurate for the specific data
distribution\, rather than being generic for a smoothness class\, and (4)
rates that are accurate for the distribution as well as the specific query
point. Along the way\, we introduce a notion of 'margin' for nearest neig
hbor classification. This is a function m(x) that assigns a positive real
number to every point in the input space\; and the size of the data set ne
eded for NN (with adaptive choice of k) to predict correctly at x is\, rou
ghly\, 1/m(x). The statistical background needed for understanding these r
esults is minimal\, and will be introduced during the talk. This is joint
work with Akshay Balsubramani\, Kamalika Chaudhuri\, Yoav Freund\, and Sha
y Moran.

DESCRIPTION:Topic: Perspectives on the Generally-Relativistic Two-Body Prob
lem from Double Copy & EFT\n\nSpeaker: Radu Roiban\, Pennsylvania State Un
iversity\n\nWhile the flat space two-body problem is integrable\, the gene
rally-relativistic one is not starting at the next-to-leading order.\nIn t
he appropriate classical limit\, scattering amplitude-based techniques can
yield the classical interaction of massive bodies to all orders in their
velocities and to fixed order in the expansion in Newton's constant\, that
is a fixed order in the post-Minkowskian (relativistic weak-field) expans
ion.\nIn this talk we review an amplitudes-based framework for such calcul
ations and the derivation of the third order in the post-Minkowskian expan
sion for the conservative Hamiltonian of a compact spinless binary system.
We also describe the scattering angle at this order as well as a first co
mparison with numerical GR.

DESCRIPTION:Topic: Homological mirror symmetry for elliptic Hopf surfaces\n
\nSpeaker: Abigail Ward\, Harvard University\n\nWe show evidence that homo
logical mirror symmetry is a phenomenon that exists beyond the world of Kä
hler manifolds by exhibiting HMS-type results for a family of complex surf
aces which includes the classical Hopf surface (S^1 x S^3). Each surface S
we consider can be obtained by performing logarithmic transformations to
the product of P^1 with an elliptic curve. We use this fact to associate t
o each S a mirror 'non-algebraic Landau-Ginzburg model' and an associated
Fukaya category\, and then relate this Fukaya category and the derived cat
egory of coherent analytic sheaves on S.

AlexeiKitaev\n\nI will describe the problem of finding the homotopy type o
f the space of quantum Hamiltonians in dimension d under certain constrain
ts. The common assumptions are that the interactions have finite range and
that the ground state is separated from excited states by a constant ener
gy gap\; then the space of Hamiltonians is homotopy equivalent to the spac
e of their ground states. The problem has been solved for free-fermion Ham
iltonians\, which are given by quadratic elements of a Clifford algebra. I
n this case\, the answer is a shifted KO spectrum. I will also discuss a m
ore general setting of 'invertible systems'\, which should be described by
a different homotopy spectrum. However\, it is not known what spectrum it
is.

DESCRIPTION:Topic: Rainbow fractional matchings\n\nSpeaker: Ron Holzman\, T
echnion\n\nVideo: https://video.ias.edu/csdm/2019/1202-RonHolzman\n\nGiven
a family of m matchings in a graph G (where each matching can be thought
of as a color class)\, a rainbow matching is a choice of edges of distinct
colors that forms a matching. How many matchings of size n are needed to
guarantee the existence of a rainbow matching of size n? If G is bipartite
\, a theorem of Drisko generalized by Aharoni and Berger says that m = 2n
- 1 suffices (and is best possible). In a general graph G\, this is not th
e case\, but m = 2n is conjectured to be enough. We prove a fractional ver
sion of this conjecture\, not only for graphs but also for r-uniform hyper
graphs. The main tool is a topological result of Kalai and Meshulam. This
is joint work with Ron Aharoni and Zilin Jiang.

mathematical models describing how information is maintained and recalled
in these experiments. Surprisingly\, they provide a very good description

ker: Yin Li\, King\'s College London\n\nAn exact Calabi-Yau structure\, or

uctures in the sense of Kontsevich-Vlassopoulos. For a Weinstein manifold\
, an exact Calabi-Yau structure on the wrapped Fukaya category induces a c
lass in the degree one equivariant symplectic cohomology\, which we call a
cyclic dilation. We prove that for many Weinstein manifolds with cyclic d
ilations\, there is an upper bound on the number of pairwise disjoint Lagr
angian spheres\, and the homology classes of these Lagrangian spheres are
non-trivial. On the other hand\, we show that the Milnor fiber of a 3-fold
triple point admits a cyclic dilation despite that there is no quasi-dila

DESCRIPTION:Topic: Dynamics of Black Holes and Gravitational Waves\n\nSpeak
er: Hyung Mok Lee\, KASI (Korea)\n\nThe advanced detectors of gravitationa
l waves detected several black hole binary mergers one neutron star merger
. Such binaries are either formed by evolution of massive binary systems o
r through dynamical processes in dense stellar systems. I will focus on th
e dynamical scenarios originating from globular clusters. The galactic nuc
lei star clusters (NC) could also provide suitable environment for the dyn
amical binary formation\, but they are likely to be much less efficient th
an globular clusters. In globular clusters\, the black holes become the mo
st massive components within 10 million years after the birth of the clust
ers. The black holes experience dynamical friction that causes central con
centration of massive black hoes in the central parts of the clusters in a
short time scale. Black hole binaries can be formed either direct capture
or by three-body processes in dense core. Under typical conditions of glo
bular clusters\, three-body processes are much more efficient than direct
capture. The binaries experience subsequent interactions with surrounding
stars (mostly black holes) and the orbit shrinks due to such interactions.
Eventually the binaries get ejected along with surrounding black holes\,
leading to nearly complete desertification of black holes in the cluster i
n a few billion years. The ejected binaries undergo passive evolution outs
ide the cluster through gravitational radiation. Some fraction of the them
will merge within Hubble time. We expect the mass ratios of two black hol
es in binaries would be close to unity. Also the spin directions are expec
ted to be randomly oriented relative to the orbital angular momentum vecto
r. iBinaries composed of a black hole and a neutron star will be very rare
among dynamical binaries. I will also describe the gravitational waves ar
ising from the hyperbolic or parabolic encounters between black holes and
detectability of such events.

DESCRIPTION:Topic: A distributional code for value in dopamine-based reinfo
rcement learning\n\nSpeaker: Matthew Botvinick\, DeepMind\n\nTwenty years
ago\, a link was discovered between the neurotransmitter dopamine and the
computational framework of reinforcement learning. Since then\, it has bec
ome well established that dopamine release reflects a reward prediction er
ror\, a surprise signal that drives learning of reward predictions and sha
pes future behavior. According to the now canonical theory\, reward predic
tions are represented as a single scalar quantity\, which supports learnin
g about the expectation\, or mean\, of stochastic outcomes. I'll present r
ecent work in which we have proposed a novel account of dopamine-based rei
nforcement learning\, and adduced experimental results which point to a si
gnificant modification of the standard reward prediction error theory. Ins
pired by recent artificial intelligence research on distributional reinfor
cement learning\, we hypothesized that the brain represents possible futur
e rewards not as a single mean\, but instead as a probability distribution
\, effectively representing multiple future outcomes simultaneously and in
parallel. This idea leads immediately to a set of empirical predictions\,
which we tested using single-unit recordings from mouse ventral tegmental
area. Our findings provide strong evidence for a neural realization of di
stributional reinforcement learning.

DESCRIPTION:Topic: A CMB Millikan Experiment with Axion Strings\n\nSpeaker:
Prateek Agrawal\, Harvard University\n\nVery light axions are a generic p
rediction of string compactifications. If cosmic strings associated with t
hese axions were produced in the early universe\, they quickly approach a
so-called scaling solution\, such that strings persist in the sky today. I
will present some remarkable signals of such strings coupled to photons.
In this string background\, there is a model-independent polarization rota
tion of CMB photons equal to $\alpha_{em}$ up to a rational number. This m
anifests itself as a rotation of E-modes in the CMB polarization to B-mode
s. The current CMB experimental sensitivity to this rotation is about 1%\,
with many orders of magnitude improvement expected for future experiments
. I will show how measuring the undetermined rational number may shed ligh
t on the quantization of electric charge in the standard model. These stri
ngs may also be visible in strongly lensed quasar systems.

DESCRIPTION:Topic: Thin groups and the arithmetic of imaginary quadratic fi
elds\n\nSpeaker: Katherine Stange\, University of Colorado\, Boulder\n\nTh
e Farey subdivision of the real line describes the action of PSL(2\,Z) and
gives a continued fraction algorithm approximating real numbers by ration
al numbers. Asmus Schmidt defined an analogue for the complex plane\, depe
nding on a choice of Euclidean imaginary quadratic field. I generalize his
construction to arbitrary imaginary quadratic fields\, which gives rise t
o an arrangement of circles into orbits of the Bianchi group PSL(2\,O_K).
Geometric aspects of this picture relate to arithmetic properties of the f
ield. Furthermore\, Apollonian circle packings arise naturally from the Ga
ussian case. The curvatures of integral Apollonian circle packings conject
urally satisfy a local-global property for which a density-one statement w
as proven by Bourgain and Kontorovich. Inspired by the viewpoint of Schmid
t arrangements\, we can define an infinite family of integral circle packi

DESCRIPTION:Topic: Entropy Rain and the Solar Convective Conundrum: Dilutio
n and Compression of Individual Convective Downflows\n\nSpeaker: Evan Ande
rs\, University of Colorado\, Boulder\n\nLarge-scale convective flows call
ed giant cells were once thought to transport the Sun’s luminosity in the
solar convection zone\, but recent observations do not detect giant cells.
The absence of giant cells is referred to as the “Solar Convective Conund
rum” and calls into question our fundamental understanding of stellar enve
lope convection. In place of large-scale flows\, some authors have suggest
ed the solar luminosity may instead be transported by small droplets of ra
pidly falling\, low entropy fluid. This “entropy rain” could propagate as
dense vortex rings\, analogous to rising buoyant “thermals” in the Earth’s
atmosphere. In this work\, we model stellar downflows as dense\, negative
ly buoyant thermals and develop an analytical theory describing their evol
ution. We verify the theory with 2D cylindrical and 3D cartesian simulatio
ns of laminar\, axisymmetric thermals in highly stratified atmospheres. Ou
r results show that dense thermals fall in two categories: a stalling regi
me in which the droplets slow down and expand\, and a falling regime in wh
ich the droplets accelerate and shrink as they propagate downwards. We est
imate that solar downflows are in the falling regime and maintain their en
tropy perturbation against diffusion until they reach the base of the conv
ection zone. This suggests that entropy rain may be an effective nonlocal
mechanism for transporting the solar luminosity.

Speaker: Gina Panopoulou\, California Institute of Technology\n\nThe abili
ty to reconstruct the 3D magnetic field in the Galactic interstellar mediu
m (ISM) is instrumental for many different scientific efforts. A 3D magnet
ic field reconstruction can inform us about the dynamics in star forming r
egions\, the origin of ultra-high energy cosmic rays\, as well as large-sc
ale Galactic processes. Such 3D maps are also necessary for accurately mod
eling polarized dust emission\, which acts as a dominant foreground contam
inating the polarization of the Cosmic Microwave Background. While modelin
g the magnetic field in 3D using 2D data has been possible in the past\, t
he advent of Gaia allows for actually measuring the field in three-dimensi
ons with unprecedented accuracy. I will present an effort towards this goa
l: tomographic mapping of the magnetic field morphology using dust-induced
starlight polarization. By combining information from a diverse set of ob
servables\, I will demonstrate what we can learn about the magnetized ISM
from such an endeavor.

must involve functions of at least 2\, 3 and 4 variables respectively (su

aHolden\n\nA random planar map is a canonical model for a discrete random
surface which is studied in probability theory\, combinatorics\, mathemati
cal physics\, and geometry. Liouville quantum gravity is a canonical model
for a random 2D Riemannian manifold with roots in the physics literature.
In a joint work with Xin Sun\, we prove a strong relationship between the
se two natural models for random surfaces. Namely\, we prove that the rand
om planar map converges in the scaling limit to Liouville quantum gravity
under a discrete conformal embedding which we call the Cardy embedding.

een exoplanetary systems and our own Solar System\, and thereby address cr
itical gaps currently facing exoplanet research: How did hot Jupiters migr

arise in the inner terrestrial zone of the average star? and how can we f

DESCRIPTION:Topic: Constraining Neutrino Mass with the Bispectrum\n\nSpeake
r: ChangHoon Hahn\, Lawrence Berkeley National Laboratory\n\nMassive neutr
inos suppress the growth of structure below their free-streaming scale and
leave an imprint on large-scale structure. Measuring this imprint allows
us to constrain the sum of neutrino masses\, Mnu\, a key parameter in part
icle physics beyond the Standard Model. However\, degeneracies among cosmo
logical parameters\, especially between Mnu and sigma8\, limit the constra
ining power of standard two-point clustering statistics. I will present wh
ether we can break these degeneracies and constrain Mnu with the next high
er-order correlation function — the bispectrum. I first examine the redshi
ft-space halo bispectrum of 800 N-body simulations from the HADES suite an
d demonstrate that the bispectrum helps break the Mnu-sigma8 degeneracy. T
hen I will present the full information content of the redshift-space halo
bispectrum down to nonlinear scales using a Fisher matrix forecast of {Om
\, Ob\, h\, ns\, sigma8\, Mnu} with 22\,000 N-body simulations of the Quij
ote suite. For kmax=0.5 h/Mpc\, the bispectrum provides Om\, Ob\, h\, ns\,
and sigma8 constraints 1.9\, 2.6\, 3.1\, 3.6\, and 2.6 times tighter than
the power spectrum. For Mnu\, the bispectrum improves the 1sigma constrai
nt from 0.2968 to 0.0572 eV — over 5 times tighter than the power spectrum
. Lastly\, I will present ongoing projects that are laying down the framew
ork for a full bispectrum analysis of DESI: including a comprehensive bias
(HOD) model\, data compression for the bispectrum\, paired-fixed simulati
ons for the bispectrum\, and efficient simulation-based inference methods.

DESCRIPTION:Topic: On the gradient-flow structure of multiphase mean curvat
ure flow\n\nSpeaker: Tim Laux\, University of California\, Berkeley\n\nVid
eo: https://video.ias.edu/analysis/2019/1209-TimLaux\n\nDue to its importa
nce in materials science where it models the slow relaxation of grain boun
daries\, multiphase mean curvature flow has received a lot of attention ov
er the last decades.\n\nIn this talk\, I want to present two theorems. The
first one is a convergence result for the vector-valued Allen-Cahn equati
on. Similar to an intriguing proof by Luckhaus-Sturzenhecker and a recent
work with Felix Otto\, we derive the convergence of the phase field to a d
istributional solution of multiphase mean curvature flow. The second resul
t is a weak-strong uniqueness principle: as long as a strong solution to m
ultiphase mean curvature flow exists\, any distributional solution with op
timal energy dissipation rate has to coincide with this solution.\n\nBoth
proofs are based on the gradient-flow structure of multiphase mean curvatu
re flow. In particular\, for the first result\, we construct a phase-field
version of the tilt-excess\, a well-known functional in geometric measure
theory. For the second result\, we define a suitable relative entropy fun
ctional\, which in this geometric context may be viewed as a time-dependen
t variant of calibrations. Just like the existence of a calibration guaran
tees that one has found a global minimum\, the existence of a time-depende
nt calibration ensures that the route of steepest descent in the energy la
ndscape is unique and stable.\n\nThis is joint work with Julian Fischer\,
Sebastian Hensel\, and Thilo Simon.

lemma. It has applications in fields such as number theory and theoretica
l computer science. For every fixed graph H\, the H-removal lemma gives a
highly nontrivial equivalence between the density of H in G and the L1 dis
tance between a graph G to the set of H-free graphs. The quantitative esti
mates remains a big open question in graph theory. In this talk\, I will c

the galaxy’s total mass. This halo size translates into a large diameter o
f 42 degrees on the sky for an M31–Milky Way distance of 785 kpc\, but its
presumably low surface brightness makes it challenging to detect with gam
ma-ray telescopes. Using data from the Fermi Large Area Telescope\, we mak

romeda's outer halo\, and perform an in-depth analysis of the systematic u

calaureat). The film follows the brilliant daughter of a successful physic
ian as she prepares for college. She has won a scholarship to Cambridge Un
iversity\, on the condition that she receives top grades in her final exam
s. A dramatic incident the day before the latter destabilizes her and jeop
ardizes her chances. Her distressed father is offered by a police official
a deal to fix the exams’ results. The film subtly explores the meandering
s of corruption in the former Socialist country. In The Guardian\, Peter B
radshaw writes\, “Graduation is an intricate\, deeply intelligent film\, a
nd a bleak picture of a state of national depression in Romania\, where th
e 90s generation hoped they would have a chance to start again.” The film
won the 2016 Cannes Film Festival award for Best Director\, and the 2016 C
hicago International Film Festival award for Best Actor went to Adrian Tit
ieni.\n\nThis film runs 2 hours and 8 minutes.\n\nA post-screening discuss
ion will be led by Virág Molnár\, Associate Professor of Sociology at The
New School\, and Naor Ben-Yehoyada\, Assistant Professor in the Department
of Anthropology at Columbia University\, both current Members in the Scho

DESCRIPTION:Topic: Probing Microphysics of the Hot Intracluster Medium\n\nS
peaker: Irina Zhuravleva\, University of Chicago\n\nGalaxy clusters are th
e largest dark matter-dominated objects in the Universe with the most mass
ive baryonic component in the form of hot\, X-ray-emitting plasma. Due to
their size and relative simplicity\, clusters are unique laboratories for
probing plasma properties on microscales\, such as turbulence\, viscosity\
, heat conduction\, magnetic fields. These properties remain largely unmea
sured and their theoretical predictions vary by orders of magnitude. In my
talk\, I will discuss how statistical properties of gas perturbations imp
rinted in the high-resolution X-ray images of galaxy clusters are used to
probe gas turbulence\, the effective equation of state of small-scale pert
urbations and plasma behavior on spatial scales comparable to Coulomb mean
free path. The latter allows us to probe transport processes\, in particu
lar\, gas viscosity in the bulk intergalactic plasma. At the end of my tal
k\, I will briefly discuss how we will measure the statistical properties
of the gas velocity field with the near-future XRISM mission.

is is an update on the talk I gave about 10 years ago on this seminar. The
arithmetic Gan-Gross-Prasad (AGGP) conjecture\, a high dimensional genera
lization of the Gross–Zagier theorem\, relates the height pairing of arith
metic diagonal cycles on certain product Shimura varieties to the first ce
ntral derivative of Rankin-Selberg tensor product L-functions. The arithme
tic fundamental lemma conjecture arises from the relative trace formula ap

DESCRIPTION:Topic: Measurements of CMB Polarization with the Polarization M
odulation Technique\n\nSpeaker: Satoru Takakura\, Kavli Institute for the
Physics and Mathematics of the Universe\n\nAs our last journal club for th
e fall semester Satoru Takakura (IPMU) will deliver his Dicke talk. Abstra
ct: Polarization anisotropies on the cosmic microwave background (CMB) is
an interesting target for astroparticle physics. Especially\, the parity-o
dd component\, the so-called B-mode\, in degree scale is a unique probe of
primordial gravitational waves from the cosmic inflation. The POLARBEAR e
xperiment is a ground-based CMB polarization measurement at the Atacama De
sert in Chile with 1\,274 transition-edge-sensor (TES) bolometers sensitiv
e to the 150 GHz band on a 2.5 m aperture telescope. One of the challenges
for the degree-scale measurement is the mitigation of the low-frequency n
oise\, the so-called 1/f noise. Since 2014\, POLARBEAR has employed a pola
rization modulation technique using a continuously rotating half-wave plat
e. The same technique is used in the Atacama B-mode Search (ABS) experimen
t at Princeton and the small aperture telescopes in the Simons Observatory
(SO) experiment. In POLARBEAR\, however\, we find that there are remainin
g 1/f noises due to instrumental leakages and polarized clouds. I am inter
ested in improving the characterization of the 1/f noise using the ABS dat
a and also developing a new cloud monitor\, which will contribute to SO to
measure inflationary B-modes. Should you wish to order lunch\, you may do
so by 10am on Thursday here:

DESCRIPTION:Topic: Topological Quantum Phases\n\nSpeaker: Alexei Kitaev\, C
altech\; Distinguished Visiting Professor\, School of Natural Sciences\, I
AS\n\nI will discuss topological classification of gapped many-body Hamilt
onians and their ground states in dimension d. In general\, the problem is
too hard as it includes diverse phenomena such as degenerate ground state
s on the torus\, anyons\, and fractons. There is\, however\, hope to fully
understand short-range entangled\, or 'invertible' systems\, which do not
have the aforementioned features but may possess gapless edge modes. In t
he case of non-interacting fermions\, the topological classification is ba
sed on K-theory. I will argue that general invertible systems are describe
d by some homotopy spectrum (or equivalently\, generalized cohomology theo
ry). However\, the exact answer is not yet known.

DESCRIPTION:Topic: Thresholds Versus Fractional Expectation-Thresholds\n\nS
peaker: Keith Frankston\, Rutgers University\n\nGiven an increasing family
F in {0\,1}^n\, its measure according to mu_p increases and often exhibit
s a threshold behavior\, growing quickly as p increases from near 0 to nea
r 1 around a specific value p_c. Thresholds of families have been of great
historical interest and a central focus of the study of random discrete s
tructures (e.g. random graphs and hypergraphs)\, with estimation of thresh
olds for specific properties the subject of some of the most challenging w
ork in the area. In 2006\, Kahn and Kalai conjectured that a natural (and
often easy to calculate) lower bound q(F) (which we refer to as the “expec
tation-threshold”) for the threshold is in fact never far from its actual
value. We prove a fractional version (proposed by Talagrand) of this so ca
lled “expectation-threshold” conjecture showing that for any increasing fa
mily we have p_c(F) = O(q_f(F) log \ell(F))\, where q_f is the “fractional
expectation-threshold” and \ell(F) is the maximum size of a minimal eleme
nt of F. This result easily implies several previously difficult results i
n probabilistic combinatorics such as thresholds for perfect hypergraph ma
tchings (Johansson–Kahn–Vu) and bounded-degree spanning trees (Montgomery)
. Our approach builds on a recent breakthrough of Alweiss\, Lovett\, Wu an
d Zhang on the Erdős–Rado “Sunflower Conjecture.” This is joint work with
Jeff Kahn\, Bhargav Narayanan\, and Jinyoung Park.

DESCRIPTION:Topic: An Improved Cutting Plane Method for Convex Optimization
\, Convex-Concave Games and its Applications\n\nSpeaker: Zhao Song\, Membe
r\, School of Mathematics\n\nGiven a separation oracle for a convex set $K
\subset \mathbb{R}^n$ that is contained in a box of radius $R$\, the goal
is to either compute a point in $K$ or prove that $K$ does not contain a
ball of radius $\epsilon$. We propose a new cutting plane algorithm that u
ses an optimal $O(n \log (\kappa))$ evaluations of the oracle and an addit
ional $O(n^2)$ time per evaluation\, where $\kappa = nR/\epsilon$.\n\n- Th
is improves upon Vaidya's $O( \text{SO} \cdot n \log (\kappa) + n^{\omega+
1} \log (\kappa))$ time algorithm [Vaidya\, FOCS 1989a] in terms of polyno
mial dependence on $n$\, where $\omega\n- This improves upon Lee-Sidford-W
ong's $O( \text{SO} \cdot n \log (\kappa) + n^3 \log^{O(1)} (\kappa))$ tim
e algorithm [Lee\, Sidford and Wong\, FOCS 2015] in terms of dependence on
$\kappa$.\n\nFor many important applications in economics\, $\kappa = \Om
ega(\exp(n))$ and this leads to a significant difference between $\log(\ka
ppa)$ and $\text{poly}(\log (\kappa))$. We also provide evidence that the
$n^2$ time per evaluation cannot be improved and thus our running time is
optimal. A bottleneck of previous cutting plane methods is to compute leve
rage scores\, a measure of the relative importance of past constraints. Ou
r result is achieved by a novel multi-layered data structure for leverage
score maintenance\, which is a sophisticated combination of diverse techni
ques such as random projection\, batched low-rank update\, inverse mainten
ance\, polynomial interpolation\, and fast rectangular matrix multiplicati
on. Interestingly\, our method requires a combination of different fast re
ctangular matrix multiplication algorithms. Our algorithm not only works f
or the classical convex optimization setting\, but also generalizes to con
vex-concave games. We apply our algorithm to improve the runtimes of many
interesting problems\, e.g.\, Linear Arrow-Debreu Markets\, Fisher Markets
\, and Walrasian equilibrium.This is a joint work with Haotian Jiang\, Yin
Tat Lee\, and Sam Chiu-wai Wong.
