ack holes are expected to exhibit universal 'random\nmatrix' behavior at l
ate times\, indicative of quantum chaos. The\napproach to a late-time plat
eau in the spectral form factor (SFF) is\na probe of this behavior. In thi
s talk we study the SFF in\ndouble-scaled matrix integrals\, dual to two-d
imensional black holes\,\nand conjecture a formula for the SFF in the limi
t of large time\,\nlarge density of states\, and fixed temperature. This f
ormula provides\na convergent expansion for the plateau as a sum over spac
etime\ntopologies (spacetime wormholes). To understand the origin of this
\nseries\, we compare to the semiclassical theory of “encounters” in\nperi
odic orbits. In Jackiw-Teitelboim (JT)\ngravity\, encounters correspond to
portions of the moduli space\nintegral that mutually cancel (in the orien
table case) but\nindividually grow at low energies. At genus one we show h
ow the full\nmoduli space integral resolves the low energy region and give
s a\nfinite nonzero answer.

nowmass 2021 was the community support\nfor R&D towards a future muon coll
ider. We propose a new beam dump\nexperiment at a future TeV-scale muon co
llider\, and the demonstrator\nfacilities along the way. A beam dump would
be an economical and\neffective way to increase the discovery potential o
f the collider\ncomplex in a complementary regime. In this work we conside
r vector\nmodels such as the dark photon and Lμ−Lτ gauge boson as new\nphy
sics candidates and explore which novel regions of parameter space\ncan be
probed with a muon beam dump. We find that\, at the full center\nof mass
energies\, for the dark photon model\, we gain sensitivity in\nthe moderat
e mass (MeV - GeV) range at both higher and lower couplings\ncompared to e
xisting and proposed experiments\, and gain access to\npreviously untouche

o cover the basics towards the feasibility of\na muon collider\, as well a
s the physics potential at various\ndemonstrator facilities on the way to
R&D for the full 10+ TeV\ncollider.

https://www.ias.edu/covid-19-procedures\n\nABSTRACT: Consider smooth solut
ions to the 3d Navier-Stokes for\ndivergence-free vector fields $u^\vareps
ilon$:\n\[\n\partial_t u^\varepsilon + {\rm div}\, (u^\varepsilon \otimes
\nu^\varepsilon ) + \nabla p^\varepsilon = \varepsilon \Delta\nu^\varepsil
on\n\]\nWhile the balance of the energy is\n\[\n\frac{d}{dt} \int |u^\vare
psilon|^2 (x\,t)\, dx = - 2 \varepsilon \int\n|Du^\varepsilon|^2 (x\,t)\,
dx\, \,\n\]\nit is a tenet of the theory of fully developed turbulence tha
t in a\nvariety of situations the size of the left hand side should typica
lly\nbe independent of $\varepsilon$. However this ``anomalous''\ndissipat
ion should not be triggered by an hypothetical initial datum\n$u^\varepsil
on (\cdot\, 0)$ in which we ignite lots of oscillations: a\nrule of thumb
would be that\, if the {\em linear} Stokes equations\nexhibit a similar be
havior\, then the roughness of the initial data is\ncertainly excessive.\n
\nProducing rigorous mathematical examples of this prediction is hard: a\n
tight control on the smoothness of the initial data forces the\nsolutions
to converge to classical solutions of the Euler equation and\ntherefore ru
les out any possible dissipation\, unless one shows a quite\nsevere blow-u
p for smooth solutions of Euler\; for sufficiently rough\ninitial data thi
s obstruction is absent\, but proving something about\nthe solutions of Na
vier-Stokes becomes very challenging.\n\nIn a recent joint work with Elia
Brué we study what happens if we\nintroduce a forcing term $f^\varepsilon$
. The problem is compatively\neasier and it can be proved that there is an
exact regularity\nthreshold below which anomalous dissipation happens in
some examples\nand above which it would only be possible through a blow-up
scenario.\nSurprisingly one side of the problem is linked with some funda
mental\nquestions about solving ODEs with rough coefficients. \n\n

New Physics searches and QCD precision measurements\ninvolve the study of
jet substructure for final state hadrons.\nTraditionally\, event shape obs
ervables have been the state of the art\nfor studying jets\, though recent
ly it has been better understood that\nmeasuring correlation functions of
energy flow operators inside a jet\ncan be a very powerful tool for phenom
enology\, which naturally stems\nfrom first principles of quantum field th
eory. \n\nIn this talk I will present a bridge between the theoretical pro
gress\nmade to understand the energy correlators from the field theory\npe
rspective and their practical implementation into the real world of\nhadro
n colliders. I will show a factorization formula we have derived\nusing so
ft-collinear effective theory (SCET) that makes it possible to\nstudy such
energy correlators inside a jet in the complicated LHC\nenvironment. I wi
ll show how extending such a factorization theorem to\nheavy quark jets pr
esents new opportunities to observe intrinsic mass\neffects of elementary
particles in QCD.\n\nI will also discuss that it is possible to learn more
about the\nproperties of higher point energy correlators using analyticit
y\nmethods developed for scattering amplitudes. \n\nThe talk is based on

the tameness of conformal\nfield theories and effective theories that can
be coupled to quantum\ngravity. In particular\, we present tameness conje

.1\n\nABSTRACT: Supersymmetric black holes in Anti de-Sitter space have\nr
ecently been shown to have a large number of exactly degenerate\nmicrostat
es. In the first part of the talk\, we will review how AdS5\nblack hole mi
crostates may be reliably counted in the dual N=4 SYM\ntheory using the su
perconformal index\, a partition function preserving\n1/16-supersymmetry.
We discuss some of the surprising implications for\nthe bulk gravitational
path integral as well as the relationship to\nsuper JT gravity.\n\nWith t
he goal of understanding more detailed properties involving the\nBPS black
holes using the bulk description\, we will turn to the\nquestion of wheth
er there are supersymmetric probes of the black hole\nwhich have an exact
field theory dual. We find one such candidate is\nthe superconformal index
with the insertion of a Gukov-Witten surface\noperator of N=4 SYM\, dual
to a D3 brane which wraps the AdS5 black\nhole horizon. We find a saddle w
ith a large N growth which can be\nexactly matched to the probe brane acti
on. In addition to detecting\nthe familiar deconfinement transition associ
ated to the dominance of\nthe bulk black hole saddle\, this provides an ex
ample of a system in\nwhich a black hole interacts with other degrees of f
reedom which has a\nmicroscopic description.

CT: The CνB is a cosmological relic analogous to the CMB\, and\ncontains i
nformation about the universe before it was one-second-old.\nReflection of
relic neutrinos from the surface of the Earth creates a\nsignificant loca
l neutrino-antineutrino asymmetry in a shell seven\nmeters thick around th
e Earth's surface. This asymmetry far exceeds\nthe expected primordial lep
ton asymmetry. The resulting gradient of\nthe net neutrino density evades
the forty-year-old “no-go” theorem\non the vanishing of O(G_Fermi) neutri
no forces on matter.\n\nThese forces can be further enhanced by using 1-10
0 meter structures\nwith shape reminiscent of a sea-urchin: they consist o
f rods of width\nw and length L>>w periodically arranged on the surface of
the sphere\nof radius R~L. Such a structure functions as a diffraction gr
ating for\nrelic neutrinos and the induced neutrino-antineutrino asymmetry
at its\ncenter may point to a new class of experiments to detect the CνB
in a\nlaboratory setting. At the same time\, such structures can be used t

V6VkRUM3hkM2dFSlo2QWJiUWtPdz09\n\nABSTRACT: Perhaps the most important pro
blem in physics or quantum\nchemistry is to determine properties of the gr
ound state of an\ninteracting system of fermions. As a quantum mechanical
problem\,\nthere may be no efficient classical witness to the ground stat
e\nenergy\, or even to an approximation of that energy. A commonly\nconsi
dered witness is a so-called “Gaussian state”\, or free\nfermion wavefunct
ion. As a prominent example \, the Sachdev-Ye-Kitaev\n(SYK) model has no
Gaussian state which achieves a good approximation\nto the energy\; this m
odel is sometimes considered as one of the\n“most entangled” or “most stro
ngly interacting” models\npossible. I will discuss applications of the su
m-of-squares method\nto this model. Sum-of-squares is a semidefinite prog
ramming\nrelaxation. I will show that this method can give classically\ne
fficient constant-factor lower bounds on the energy\, and it inspires\na q
uantum algorithm which gives constant-factor upper bounds. Joint\nwork wi
th R. O’Donnell.

DESCRIPTION:Topic: Traintracks All the Way Down\n\nSpeakers: Andrew McLeod
\n\nAffiliation: CERN\n\nABSTRACT: Over the last few years\, much has been
learned about the\ntypes of special functions that Feynman diagrams give
rise to near\ninteger dimensions. In this talk\, I further explore this qu
estion by\nstudying a new infinite class of planar Feynman diagrams\, whic
h can be\nconstructed by sequentially intersecting so-called traintrack\nd
iagrams. After describing how to derive a 2L-fold integral\nrepresentation
of any L-loop diagram in this class\, I will show that\nthese diagrams al
ways give rise to integrals over (L−1)-dimensional\nvarieties for generic
external momenta. I will then go on to\ndemonstrate that (products of) the
se diagrams are related at adjacent\nloop orders by a large class of secon
d-order differential operators\,\nwhose number grows linearly with L and w
hich can be used to\nrecursively expose much of the analytic structure exh
ibited by these\ndiagrams.

e obtain all solutions of the Wheeler-DeWitt equation with\npositive cosmo
logical constant for a closed universe in the\nlarge-volume limit. We defi
ne a natural norm on the solution space and\nthereby obtain a description
of the Hilbert space of quantum gravity\nin an asymptotically de Sitter sp
acetime. This provides the finite G_N\ngeneralization of the Hilbert space
constructed by Higuchi using group\naveraging. All the states in this Hil
bert space share the symmetries\nof the Euclidean vacuum. We use this prop
erty to generalize the\nprinciple of holography of information to de Sitte
r space:\ncosmological correlators (defined as appropriately gauge-fixed\n
observables) in an arbitrary small region suffice to completely\nspecify t
he state.\n\nReferences:\n1) https://arxiv.org/abs/2303.16315\n2) https://

gISU7.1\n\nABSTRACT: Some aspects of the black hole spectrum\, coming from
\nspacetime wormhole contributions\, can be modeled by a random matrix\nen
semble. It is important to understand the appropriate ensemble for\ntheori
es with extended supersymmetry\, since for example this is the\ncase for s
ystems with known gravity duals coming from string theory.\nConcretely\, i
n this talk we will present a random matrix ensemble for\nquantum mechanic
s with two supercharges\, and to illustrate the\nrelation with black holes
we will show that it is dual to N=2 JT\ngravity in AdS\, after summing ov
er wormholes.

Ev3RMKL8ssHZ2nUfIwggISU7.1\n\nABSTRACT: 'Saturons' are macroscopic objects
that exhibit maximal\nmicristate degeneracy within the validity of a give
n quantum field\ntheoretic description. Due to this feature\, saturons a
nd black holes\nbelong to the same universality class with common key prop
erties. \nHowever\, as opposed to black holes\, saturons can emerge in\nre
normalizable gauge theories\, in the form of solitons\, baryons and\nother
bound states. After reviewing the general properties of\nsaturons\, we d
iscuss their potential implication for dark matter. \nDue to the maximal
microstate entropy\, the saturon dark matter can\nform as a result of a di
rect quantum transition from the radiation\nthermal bath. Correspondingly
\, it can provide a superheavy dark\nmatter formed at very low temperature
s.

DESCRIPTION:Topic: Supersymmetric Black Holes and $T\bar{T}$ Deformation\n
\nSpeakers: Swapnamay Mondal\n\nAffiliation: Dublin Institute for Advanced
Studies\n\nThis seminar will be presented IN-PERSON AND ON ZOOM.\nhttps:/
/theias.zoom.us/j/84232389159?pwd=UAWukoEv3RMKL8ssHZ2nUfIwggISU7.1\n\nABST
RACT: The entropy of supersymmetric black holes in string theory\ncompacti
fications can be related to that of a D- or M-brane system\,\nwhich in man
y cases can be further reduced to a two-dimensional\nconformal field theor
y (CFT). For black holes in M-theory\, this\nrelation involves a decouplin
g limit where the black hole mass\ndiverges. We suggest that moving away f
rom this limit corresponds to a\nspecific irrelevant perturbation of the C
FT\, namely the supersymmetric\ncompletion of the $T\bar{T}$ deformation.
We demonstrate that the\nblack hole mass matches precisely with the $T\bar
{T}$ deformed energy\nlevels\, upon identifying the $T\bar{T}$ deformation
parameter with the\ninverse of the leading term of the black hole mass. W
e discuss various\nimplications for black holes and deformed CFT's\, inclu
ding a Hagedorn\ntemperature for wrapped M5-branes\, and potential change
of\ndegeneracies in the deformed theory.
