DESCRIPTION:Topic: Endothermic Self-interacting Dark Matter in Milky Way-li
ke Halos\n\nSpeakers: Stephanie O’Neil\n\nAffiliation: Massachusetts Insti
tute of Technology\n\nABSTRACT: Self-interacting dark matter (SIDM) offer
s the potential\nto mitigate some of the discrepancies between simulated c
old dark\nmatter (CDM) and observed galactic properties. In various SIDM
\nmodels\, dark matter particles can scatter with each other in elastic\no
r inelastic collisions. In my talk\, I will discuss the effects of\nelast
ic and inelastic scattering in Milky Way-sized halos and\nsatellites in da
rk matter-only zoom-in simulations. In particular\,\nI will discuss a mod
el with a high probability of endothermic\nreactions\, which has been expl
ored less in the literature\, in addition\nto exothermic and elastic react
ions. The exothermic and elastic\nreactions alleviate small-scale discrep
ancies while the endothermic\nreactions provide a mechanism for low-energy
particles in the early\nuniverse to inelastically scatter.

DESCRIPTION:Topic: The Gregory--Laflamme Instability of the 5D Schwarzschil

umbia University\n\nABSTRACT: I will discuss a direct rigorous mathematica
l proof of the\nGregory--Laflamme instability for the 5D Schwarzschild\nbl
ack string. This is a mode instability at the level of the\nlinearised vac
uum Einstein equation. Under a choice of ansatz for the\nperturbation and
a gauge choice\, the linearised vacuum Einstein\nequation can be reduced t
o a Schrödinger eigenvalue equation to which\nan energy functional is assi
gned. It is then shown by direct\nvariational methods that the lowest eige
nfunction gives rise to an\nexponentially growing mode solution which has
\nadmissible behaviour at the future event horizon and spacelike\ninfinity
in harmonic/transverse-traceless gauge.

completeness of boundary observables (e.g.\nS-matrix in flat space or CFT

k Institute for Gravitational Physics (Albert Einstein Institute)\n\nABSTR
ACT: The coalescence of compact binaries and the gravitational\nwaves prod
uced in this process provide an unique view into gravity in\nits dynamical
\, nonlinear regime. Proeminent during a\nblack-hole coalescence is the pl
unge-merger stage\, when the black\nholes collide at a large fraction of t
he speed of light and around\nwhich the gravitational-wave luminosity peak
s. How robust are\nthe predictions of general relativity at this stage? I
will present a\nnew parametrized waveform model within the effective-one-b
ody\nformalism that allows for deviations from general relativity in\nthe
plunge-merger-ringdown stage of nonprecessing\, quasicircular\nblack-hole
binaries. I will discuss the application of this waveform\nmodel to analyz
e the black-hole binary events GW150914 and GW200129.\nI will use GW200129
to discuss the importance of waveform systematics\nand of data-quality wh
en interpreting tests of general relativity with\npresent day gravitationa

c Measurements\n\nSpeakers: Katja Nowack\n\nAffiliation: Cornell Universit
y\n\nABSTRACT: Transport currents can flow in unexpected ways through a\ns
ample\, particularly in dissipationless conductors. In this talk\, I\nwil
l discuss how we use a magnetic probe to understand how electrical\nconduc
tion happens in two types of dissipationless conductors. First\,\nwe study
microstructures fabricated from a heavy-fermion\nsuperconductor that exhi
bit unusual resistive superconducting\ntransitions. We show that this beha
vior is explained by a spatially\nmodulated transition temperature\, and w
e discover that local strain is\nthe cause of the spatial modulation. Seco
nd\, we visualize how a\nnon-equilibrium current flows in a quantum anomal
ous Hall insulator by\nimaging the magnetic field produced by the current.
Surprisingly\, we\nfind that the current can flow in the bulk of the samp
le within the\nquantized regime.

E5SUR4OUxvV0ZacVdWQT09\n\nABSTRACT: Tensor models exhibit a melonic large-
N limit. They were\nfirst introduced in zero dimension in the context of r
andom geometry\nand quantum gravity. They were then generalized in d dimen
sions where\nthey give rise in the infrared to a new kind of CFTs\, analyt
ically\naccessible\, called melonic CFTs. In the first part of the talk\,
I will\nbriefly review melonic CFTs and present in particular the long-ran
ge\nbosonic O(N)^3 model. In the second part of the talk\, I will show tha
t\nthis model respects the F-theorem at large N. The F-theorem states\ntha
t in three dimensions the sphere free energy of a CFT must\ndecrease betwe
en ultraviolet and infrared fixed points. It has been\nproven for unitary
CFTs but only hints of unitarity were found at\nlarge N for the long-range
O(N)^3 model and it is non-unitary at\nfinite N. This model thus provides
a new non-trivial example of the\nF-theorem.

owed us to study the properties of black\nholes and neutron stars more pre

e the earliest moments in our\nuniverse’s history. In this talk\, I will d

detectors\, I\nwill present evidence for a correlation between the redshi

ectromagnetic counterpart along with constraints on the neutron\nstar equa

DESCRIPTION:Topic: Deep Learning as a General Framework to Unveil the Natur
e of Dark Matter\n\nSpeakers: Francisco Villaescusa-Navarro\n\nAffiliation
: Flatiron Institute\n\nABSTRACT: The formation and evolution of structure
s in the Universe\nis expected to be affected by the nature and properties
of dark\nmatter. For this reason\, we can made use of cosmological and\na
strophysical observations to learn about dark matter. Unfortunately\,\nthe
re are multiple intrinsic complications associated to the search of\nthose
signatures: 1) numerical simulations are usually needed to\ncapture the n
on-linear physics involved on the relevant scales\, 2)\nuncertain astrophy
sical processes can mimic the dark matter signal\,\nand 3) the lack of an
optimal quantity where the expected signal is\nmaximum complicates the sea
rch. In this seminar I will present a\ncollection of ideas on how we can m
ade use of deep learning to\napproach these problems. I will first show ho
w neural networks can to\nfocus on the relevant physics while marginalizin

s: Roland Bauerschmidt\n\nAffiliation: Cambridge University\n\nABSTRACT: T
he use of different perspectives on a problem is a very\npowerful principl
e in statistical physics\, and has been especially\nimportant in mathemati
cal physics. I will illustrate this theme with\nold and recent application
s. These include the interpretation of QFTs\nat imaginary time as statisti
cal fields\, the relation of statistical\nfields to lattice models such as
percolation\, polymers\, or spanning\nforests\, the bosonization of fermi
onic theories\, and many others.\nThese connections are useful in both dir
ections\, and often provide\ncomplementary insight on a problem\, very dif
ficult understand without\nthem.

assless QED\, we find that the classical U(1) axial\nsymmetry is not compl
etely broken by the Adler-Bell-Jackiw anomaly.\nRather\, it is resurrected
as a generalized global symmetry labeled by\nthe rational numbers. Intuit
ively\, this new global symmetry in QED is\na composition of the naive axi
al rotation and a fractional quantum\nHall state. The conserved symmetry o
perators do not obey a group\nmultiplication law\, but a non-invertible fu
sion algebra. We further\ngeneralize our construction to QCD\, and show th
at the neutral pion\ndecay can be derived from a matching condition of\nth
e non-invertible global symmetry. Finally\, we find\na non-invertible Gaus
s law in axion-Maxwell theory.

DESCRIPTION:Topic: Relatively non-degenerate estimates on Kerr de Sitter sp
acetimes\n\nSpeakers: Georgios Mavrogiannis\n\nAffiliation: Rutgers Univer
sity\n\nABSTRACT: We will start discussing a new method of how to prove\ne
xponential decay for the solutions of the wave equation on a\nSchwarzschil
d de Sitter black hole spacetime by exploiting a novel\n'relatively non-de
generate' estimate. This estimate does not\ndegenerate at trapping. The ma
in ingredient in proving this estimate\nis to commute with a novel vector
field that 'sees' trapping. Then\, we\nwill discuss a natural generalizati
on of the vector field commutation\nin Schwarzschild de Sitter to the enti
re subextremal Kerr de Sitter\nblack hole spacetime\, by commuting with a
pseudodifferential operator.\nThere are more technicalities because of the
elaborate nature of\ntrapping. Time permitting\, we will discuss how to u
se this black box\nestimate to prove stability and exponential decay for t
he solutions of\na quasilinear wave equation on Kerr de Sitter.

DESCRIPTION:Topic: Liquid Crystals Meet Elastomers\n\nSpeakers: Kaushik Bha
ttacharya\n\nAffiliation: California Institute of Technology\n\nABSTRACT:
Liquid crystal elastomers are rubbery solids with liquid\ncrystal mesogens
incorporated into their polymer chains. These solids\ncombine the entropi
c elasticity of rubber with the orientational phase\ntransitions of liquid
crystals. The deformation and orientational\norder are coupled\, giving r
ise to a rich variety of phenomena\nincluding ultra-soft mechanical behavi
or\, stripe domains and\nspontaneous shape-morphing. When made as slender
structures\, the\nstructural instability of slender structures and the mat
erial\ninstabilities of liquid crystal elastomers combine and compete in\n
interesting ways. They also can be a platform for coupling mechanical\ndef
ormation to light and other stimuli. This talk will provide an\nintroducti
on to these materials\, explain their unusual mechanics and\nphysics\, and
illustrate these with examples.

tially from early Universe processes. In the nHz band\,\nsupermassive blac
k hole binaries generate a SGWB\, and there have been\nhints that a detect

akers: Sanjay Moudgalya\n\nAffiliation: Caltech\n\nTHIS TALK WILL BE HELD
IN-PERSON IN JADWIN HALL\, PCTS ROOM 407 AND ON\nZOOM:\nhttps://princeton.
zoom.us/j/97248927011?pwd=SWFiNWFwZWE5SUR4OUxvV0ZacVdWQT09\n\nABSTRACT: Th
e study of symmetry lies at the heart of various parts of\nphysics. In equ
ilibrium physics\, symmetries are useful in classifying\nphases of matter
and in non-equilibrium physics\, they are necessary to\nunderstand the phe
nomenon of thermalization. Most symmetries\nconventionally studied in the
literature are examples of so-called\non-site unitary symmetries. While su
ch symmetries are sufficient to\nexplain several physical phenomena\, the
recent discovery of weak\nergodicity breaking in quantum many-body systems
\, particularly the\nphenomena of Hilbert Space Fragmentation and Quantum
Many-Body Scars\,\nhas called for a generalization of the notion of symmet
ry. The\nconventional theory of thermalization in quantum many-body system
s\ndemands that all states within a given symmetry sector can be\nconnecte
d to each other under the dynamics of the system. However\,\nquantum many-
body systems exhibiting weak ergodicity breaking possess\nadditional close
d subspaces that are dynamically disconnected from the\nrest of the Hilber
t space. These subspaces cannot be explained in\nterms of conventional sym
metries\, which leads to a breakdown of\nconventional thermalization in su
ch systems. In this talk\, I will\ndiscuss a general mathematical framewor
k to define symmetries based on\nso-called commutant algebras\, which lead
s to a generalization of the\nnotion of symmetry beyond the conventional o
nes. This provides a\nprecise explanation of weak ergodicity breaking in t
erms of\nunconventional non-local symmetries\, allows us to cast various\n
different dynamical phenomena in the literature into a single unified\nfra
mework\, and also opens up several questions on symmetries.\n\nReferences:

DESCRIPTION:Topic: Count Your Halos\n\nSpeakers: Annika Peter\n\nAffiliatio
n: Ohio State University\n\nABSTRACT: One of the strongest predictions of
the standard cold dark\nmatter paradigm is the hierarchy of structure down
to Earth-mass\nscales. However\, individual self-bound clumps of dark\nm
atter--'halos'--are difficult to detect directly. Instead\, we use\ngalax
ies as lampposts for halos. By counting galaxies\, we can\nmeasure the un
derlying population of dark matter halos. In this\ntalk\, I describe resu
lts that seem completely at odds with each other\nin measuring the populat
ion of small halos. I argue that the\nresolution to the problem is a bett
er mapping between galaxies\nand halos. I will show what my group is doin
g so far to address the\nproblem\, and what opportunities lie ahead in the
wide-field surveys of\nthe 2020's.

DESCRIPTION:Topic: The Black Hole at Our Galactic Center\n\nSpeakers: Rames
h Narayan\n\nAffiliation: Harvard University\n\nABSTRACT: At the center of
our Milky Way Galaxy lives a compact\nmassive object called Sagittarius A
* (Sgr A*) which is believed to be\na black hole. Its mass\, as inferred f
rom the orbits of gravitationally\nbond stars as well as from direct image
s obtained by the Event Horizon\nTelescope\, is 4 million solar masses. Ga
s accreting gravitationally on\nSgr A* is in an unusual regime of plasma p
hysics whose properties are\nthe focus of the accompanying joint PG/PCTS W
orkshop. While it seems\nhighly likely that Sgr A* is indeed a black hole\
, with an event\nhorizon\, it would be wise to ask if alternative models a
re also\nviable. The talk will describe efforts to eliminate some of the\n
alternatives.

DESCRIPTION:Topic: Fully Nonlinear ray-tracing in Cosmological Simulations
with Numerical Relativity\n\nSpeakers: Hayley Macpherson\n\nAffiliation: U
niversity of Chicago\n\nABSTRACT: High-precision cosmological surveys are
due to deliver\nmeasurements accurate to the percent level. In order to en
sure we\ncorrectly interpret these data\, we need to be sure that our\ncos
mological model is accurate. A key component of the standard\ncosmological
model is the assumption of a homogeneous and isotropic\nspace-time metric
\; the FLRW space-time. State-of-the-art cosmological\nsimulations approxi
mate the dynamics of structure formation using\nNewtonian gravity combined
with a background FLRW space-time which\nevolves independently of the mat
ter dynamics. Numerical relativity is\na computational method which allows
us to relax these simplifying\nassumptions and consider the full interact
ion of matter and space-time\nas described by general relativity (GR). I w
ill provide a brief\nbackground on the use of numerical relativity for cos
mological\nsimulations before discussing my framework to create synthetic
\nobservables which are free from common simplifying assumptions.

DESCRIPTION:Topic: High-Precision Measurement of the W boson Mass with the
CDF II Detector\n\nSpeakers: Bo Jayatilaka\n\nAffiliation: Fermilab\n\nABS
TRACT: The mass of the W boson\, a mediator of the weak force\nbetween ele
mentary particles\, is tightly constrained by the\nsymmetries of the stand
ard model of particle physics. The Higgs boson\nwas the last missing compo
nent of the model. After observation of the\nHiggs boson\, a measurement o
f the W boson mass provides a stringent\ntest of the\nmodel. We measure th
e W boson mass\, mW\, using data corresponding\nto 8.8 inverse femtobarns
of integrated luminosity collected\nin proton-antiproton collisions at a 1
.96 TeV center-of-mass energy\nwith the CDF II detector at the Fermilab Te
vatron collider. A sample\nof approximately 4 million W boson candidates i
s used to obtain mW =\n(80\,433.5 +/-6.4 (stat) +/- 6.9 (syst)) MeV = (80\
,433.5 +/- 9.4)\nMeV\, the precision of which exceeds that of all previous
\nmeasurements combined. This measurement is in significant tension\nwith
the standard model expectation.

DESCRIPTION:Topic: Searching for Uncovered and Unexpected New Physics Signa
tures at the Energy Frontier\n\nSpeakers: Julia Lynne Gonski\n\nAffiliatio
n: Columbia University\n\nABSTRACT: The 2012 discovery of the Higgs boson
with the Large Hadron\nCollider (LHC) was a groundbreaking achievement for
high energy\nphysics. Remaining puzzles such as dark matter confirm the n
eed for\nbeyond the Standard Model physics\, and the Higgs boson can be us
ed as\na compass to determine its nature. This talk focuses on novel ATLAS
\nsearches in under-covered phase space\, specifically long-lived\nparticl
es and heavy resonances\, that make use of the Higgs along with\nadvanced
data analysis techniques such as machine learning and anomaly\ndetection f
or broad sensitivity. The High Luminosity LHC\, the\ncorresponding ATLAS d
etector upgrade\, and studies for future colliders\nare all crucial for th
e longevity of these searches. These topics are\ndiscussed in the context
of long-term planning for future experiments\nand the continued success of
the field.

DESCRIPTION:Topic: Linking Force\, Form and Function in Intestinal Organoid
s\n\nSpeakers: Xavier Trepat\n\nAffiliation: Institute for Bioengineering
of Catalonia\n\nABSTRACT: Intestinal organoids capture essential features
of the\nintestinal epithelium such as crypt folding\, spatial\ncompartment
alization of different cell types\, and cellular movements\nfrom crypt to
villus. Each of these processes and their coordination\nin time and space
requires patterned physical forces. I will present\nmaps of the three-dime
nsional cell-ECM and cell-cell forces in mouse\nintestinal organoids grown
on soft hydrogels. These maps reveal a\nnon-monotonic stress distribution
that defines mechanical and\nfunctional compartments. Mechanical compartm
entalization enables crypt\nfolding through apical constriction and collec
tive cell migration\nalong a tensile gradient. A 3D vertex model shows tha
t the shape and\nforce distribution of the crypt can be largely explained
by cell\nsurface tensions following the measured apical and basal actomyos
in\ndensity. I will also discuss how this mechanical picture is altered in
\npatient-derived colorectal cancer organoids. Our results show that\ncanc
er stem cells contribute mechanical stability to the cancer stem\ncell nic
he whereas differentiated cancer cells display are more\ndynamic phenotype
that favors metastatic progression.

DESCRIPTION:Topic: Directly Detecting Light Dark Matter\n\nSpeakers: Robert
McGehee\n\nAffiliation: University of Michigan\n\nABSTRACT: While the exp
erimental program to detect ever lighter dark\nmatter is proceeding full s
team ahead\, the theory of such light\,\ndetectable dark matter is at a cr
ossroads. I will detail two examples\nof sub-GeV hadrophilic dark matter m
odels which these future direct\ndetection endeavors may discover while hi
ghlighting the serious\nchallenges model builders face. The first achieves
probe-able direct\ndetection cross sections by way of a late-time\, dark-
sector phase\ntransition\, while the second does so by assuming the entire
thermal\nbath is reheated at very low temperatures. Both models lead to d
ark\nmatter-nucleon scattering cross sections of interest for near-future
\nexperiments for dark matter masses in the range of 100 keV-100 MeV\,\nof
ten in parts of parameter space with few or no models.

nglement\n\nSpeakers: Tadashi Takayanagi\n\nAffiliation: Yukawa Institute
for Theoretical Physics\n\nABSTRACT: Holography relates quantum many-body
systems to\ngravitational theories. Quantum entanglement plays a key role
to\nexplain how the spacetime geometries in gravity emerge from quantum\ns
ystems. A new class of holography can be found by introducing so\ncalled e
nd-of-the-world branes and has been actively studied recently.\nSuch holog
raphic models describe quantum systems with boundaries\, such\nas boundary
conformal field theories (BCFTs)\, where the boundary\ndynamics is descri
bed by gravitational degrees of freedom localized on\nthe branes. Consider
ations of quantum entanglement in these setups\nhelp us to have deep insig
hts on the black hole information problem.\nAt the same time\, they can al
so be used to analyze quantum information\naspects of non-equilibrium proc
esses. In this talk\, I will explain\nthese developments.
