5-branes\nin M-theory on the 11-dimensional maximally supersymmetric pp-wa

\n(PWMM) and show that transverse spherical fivebranes emerge as the\ndist

DESCRIPTION:I will describe a new numerical approach for calculating dynam
ical quantities in QFT in the non-perturbative regime.\n\nIn this approach
any QFT (including a gauge theory) can be formulated as a relevant pertur
bation of a UV CFT. \n\nThe states of the CFT are used as a basis to desc
ribe the resulting RG-flow. Holography motivates a certain truncation \no
f the CFT basis which allows for numerical calculation. I will provide nu
merical evidence in certain 2D and 3D theories that this truncation provid
es for an effective approximation for evaluating certain non-perturbative
quantities (like the Zamolodchikov c-function along an RG-flow). Implem
enting the method in the context of light-cone quantization has various ad
vantages including greatly simplifying flows in the large-N limit. Whethe
r such a simplification occurs depends on properties of the UV large-N CFT
and can be checked via a certain diagnostic. Here\, again\, holographic
models are useful in clarifying the issues faced by the light-cone approac
h.\n\nhttps://indico.ipmu.jp/indico/event/145/contributions/2229/

DESCRIPTION:Thermal boundary correlation functions provide a direct and ac
cessible way to probe features of an emergent bulk geometry. In free large
N gauge theories dual to higher spin gravity and tensionless string theor
y\, two point correlators of singlet operators encode propagation through
an approximate AdS spacetime at low temperatures. Contrarily\, in high tem
perature phases\, we discover characteristic signatures of bulk black hole
s. This includes the existence of evanescent modes and the exponential dec
ay of time dependent correlations\, as well as significant departure of sp
atial correlators from their bulk thermal AdS form. Surprisingly\, correla
tors reveal in addition the emergence of a new scale beyond which they rec
over their thermal AdS structure up to an overall temperature dependent no
rmalization. This finite volume effect is most prominently seen in the O(N
)/U(N) vector model in 2+1 dimensions\, dual to 3+1-dimensional Vasiliev h
igher spin gauge theory.\n\nhttps://indico.ipmu.jp/indico/event/145/contri

DESCRIPTION:Abstract: Scattering amplitudes play a prominent role not only
in high\nenergy particle physics\, but also for quantum gravity in\nasymp
totically flat spacetime.The search for a "theory at infinity” of\nthe S
-Matrix has revealed surprising geometric structures underlying\namplitude
s ranging from the string worldsheet to the amplituhedron\,\nbut these are
all geometries in auxiliary spaces as opposed to the\nspace at infinity w
here amplitudes actually live. By thinking of\namplitudes as differential
forms\, we propose a novel geometric picture\ndirectly in kinematic space
for a wide range of massless theories in\ngeneral dimensions.\n\nAs a prim
ary example\, we show that tree amplitudes of bi-adjoint\nscalars are give
n by the “volume” of an associahedron living naturally\nin kinematic s
pace\, and scattering equations act as a diffeomorphism\nfrom the open-str
ing moduli space (also an associahedron) to it. We\nfind general “scatte
ring forms” dual to color-dressed amplitudes e.g.\nfor gluons and pions
\, which is possible due to a remarkable fact --\n“Color is Kinematics
”. All these forms are well-defined in\nprojectivized space\, a property
which provide a geometric origin for\ncolor-kinematics duality.\n\nhttps:

SUMMARY:A Critique of the Fuzzball Program (Suvrat Raju\, ICTS)

UID:indico-contribution-145-2230@indico.ipmu.jp
DESCRIPTION:We explore the viability of fuzzballs as candidate microstate
geometries for the black hole\, and their possible role in resolutions of
the information paradox. We argue that if fuzzballs provide a description
of black-hole microstates\, then the typical fuzzball microstate can only
differ significantly from the conventional black-hole geometry at a Planc
k-scale-distance from the horizon. However\, precisely in this region quan
tum fluctuations in the fuzzball geometry become large and the fuzzball ge
ometry becomes unreliable. We verify these expectations through a detailed
calculation of quantum expectation values and quantum fluctuations in the
two-charge fuzzball geometries. We then examine a subset of the solution
s discovered in arXiv:1607.03908. We show\, based on a calculation of a p
robe two-point function in this background\, that these solutions\, and ot
hers in their class\, violate robust expectations about the gap in energie
s between successive energy eigenstates and also violate the eigenstate th
ermalization hypothesis. We conclude that while fuzzballs are interesting
star-like solutions in string theory\, they do not appear to be relevant
for resolving the information paradox\, and cannot be used to make valid i
nferences about black-hole interiors.\n\nhttps://indico.ipmu.jp/indico/eve

DESCRIPTION:The requirement for an ultraviolet completable theory to be we
ll-behaved upon compactification has been suggested as a guiding principle
for distinguishing the landscape from the swampland. Motivated by the wea
k gravity conjecture and the multiple point principle\, we investigate the
vacuum structure of the standard model compactified on S1 and T2. The mea
sured value of the Higgs mass implies\, in addition to the electroweak vac
uum\, the existence of a new vacuum where the Higgs field value is around
the Planck scale. We explore two- and three-dimensional critical points of
the moduli potential arising from compactifications of the electroweak va
cuum as well as this high scale vacuum\, in the presence of Majorana/Dirac
neutrinos and/or axions. We point out potential sources of instability fo
r these lower dimensional critical points in the standard model landscape.
We also point out that a high scale AdS4 vacuum of the Standard Model\, i
f exists\, would be at odd with the conjecture that all non-supersymmetric
AdS vacua are unstable. We argue that\, if we require a degeneracy betwee
n three- and four-dimensional vacua as suggested by the multiple point pri
nciple\, the neutrinos are predicted to be Dirac\, with the mass of the li
ghtest neutrino O(1-10) meV\, which may be tested by future CMB\, large sc
ale structure and 21cm line observations.\n\nhttps://indico.ipmu.jp/indico

DESCRIPTION:It has been recently shown that the deformation of an arbitrar
y two-dimensional conformal field theory by the composite irrelevant opera
tor\nTT-bar\, built from the components of the stress tensor\, is solvable
\; in particular\, the finite-size spectrum of the deformed theory can be
obtained from that of the original CFT through a universal formula. We stu
dy a similarly universal\, Lorentz-breaking deformation of two-dimensional
CFTs that possess a conserved U(1) current\, J. The deformation takes the
schematic form JT-bar and it is interesting because it preserves an SL(2\
,R) x U(1) subgroup of the original global conformal symmetries. For the c
ase of a purely (anti)chiral current\, we find the finite-size spectrum of
the deformed theory and study its thermodynamic properties. Next\, we sho
w that the holographic dual of JT-bar deformed CFTs for J chiral is AdS_3
with certain modified boundary conditions. We then use holography to argue
that the global symmetries of the model are enhanced to a Virasoro x Vira
soro x U(1) Kac-Moody algebra\, just as before the deformation\; the only
effect of the latter is to modify the\nspacetime dependence of the right-m
oving Virasoro generators\, whose action becomes state-dependent and effec
tively non-local.\n\nhttps://indico.ipmu.jp/indico/event/145/contributions

DESCRIPTION:In the context of AdS/CFT\, one of the most important problem
is to\nunderstand how CFTs describe the bulk interior of the AdS spacetime
.\nEspecially\, it is not clear whether CFTs can describe the black hole\n
interior. In order to understand it\, we construct the bulk local\nstates
which are dual to the the states locally excited by a scalar\nfields in th
e AdS black holes. For double-sided BHs dual to the\nthermofield double st
ates and single-sided BHs dual to the CFT\nboundary states\, our construct
ion correctly reproduces the classical\nspacetime not only outside the hor
izon but also its inside. We also\nanalyzed the spacetime structure dual t
o the high energy eigenstates\nin CFT with our construction. We found that
classical black hole\nspacetime can be reproduced from CFT side unless we
probe the deep\ninterior in the bulk. We found the possibility that as we
probe the\ndeep interior\, the classical notion of spacetime might break
down and\nquantum corrections cannot be neglected. It might be related to
the\nfirewall problem which has been actively argued recently.\n\nhttps://

DESCRIPTION:Recently\, using the AdS/CFT correspondence exciting new relat

and of\nthe geometry of black holes in Anti de Sitter space-times. After a
\nconcise review of the roles of entanglement measures such as e.g. the\ne
ntanglement entropy as well as of the computational complexity within\nthe
AdS/CFT correspondence\, I discuss the notion of subregion\ncomplexity of
a 2D critical state from three di erent viewpoints: the\nAdS3/CFT2 corres
pondence\, random tensor networks\, and kinematic space.\n>From the AdS3/C
FT2 point of view I explain how in the dis- continuity\nof subregion compl
exity as given by the volume within the\nRyu-Takayanagi surface is related
to the Euler characteristic of the\nre- spective bulk regions via the Gau
ss-Bonnet theorem. I then discuss\nhow the volume of these sub regions can
be calculated in kinematic\nspace\, which is the space of geodesics on th
e time-slice of AdS3\, and\npresent a new CFT expression of subregion comp
lexity. Finally\, I\npresent re- sults that qualitatively reproduce the di
scontinuity in\ncomplexity in a tensor network approach. Based on arXiv:17

DESCRIPTION:An idea to formulate string theory or M-theory by a gauge theo

nshould be lower dimensional so that a geometry in string or M-theory\,\nw
hich has higher dimensions\, must emerge from it. This suggests that\nther
e should be a phase transition in the gauge theory and that the\ngeometry
would appear as its temperature decreases. In this talk\, we\nfocus on the
BMN matrix model\, which is considered as a\nnon-perturbative formulation
of M-theory on the pp-wave geometry and\nalso conjectured to have a gauge
/gravity duality\, which relates each\nvacuum on the gauge theory side to
a bubbling geometry in the type IIA\nsupergravity. Our preliminary results
of Monte Carlo simulations show\ntwo phase transitions and one of them lo

DESCRIPTION:Recent studies of the fluctuations of an open string in AdS sp

chaos bound and share the same symmetry. An open string hangs from the\nAd
S boundary to the horizon of black brane could be dual to a 0+1\ndimension
al boundary state. To be specific\, we find that the\nfluctuation of the s
tring in charged BTZ black hole has an asymptotic\nscaling symmetry\, and
its Euclidean IR fixed point is governed by the\nquadratic order of Schwar
zian action\, which is just the low energy\neffective theory of the SYK mo
del. Considering the open string\nworldsheet also has natural reparametriz
ation symmetry\, we conjecture\nthat the action of the string worldsheet i

DESCRIPTION:Abstract: We recently used Virasoro symmetry considerations t
o propose an exact formula for a bulk proto-field φ in AdS3. In this talk
we will explain the construction and study the propagator . Many techniq
ues from the study of conformal blocks can be generalized to compute it\,
and when the results are expanded at large central charge\, they match gra
vitational perturbation theory for a free scalar field coupled to gravity
in Fefferman-Graham gauge. Although the propagator appears to be local to
all orders in perturbation theory\, we explicitly compute non-perturbativ
e effects in G ~ 1/c that spell the breakdown of bulk locality: the commut
ator (or retarded propagator) is non-vanishing at small spacelike separati
ons.\n\nhttps://indico.ipmu.jp/indico/event/145/contributions/2227/
