DESCRIPTION:Title: Holographic entanglement entropy for TTbar-deformed CFTs\nby
Luis Apolo (University of Amsterdam) as part of Integrability\, Duality a
nd related topics\n\n\nAbstract\nTTbar-deformed CFTs with a negative defor
mation parameter have been proposed to be dual to Einstein gravity on AdS3
with a finite cutoff. In this talk\, I will present an extension of cutof
f AdS3 holography that is valid for positive values of the deformation par
ameter. In this case\, turning on the deformation parameter brings the asy
mptotic boundary of AdS3 to a finite cutoff in an auxiliary AdS3 spacetime
. I will show that the theory living at the cutoff surface reproduces many
features of TTbar-deformed CFTs with a positive deformation parameter. Fu
rthermore\, I will give a geometric prescription for computing the hologra
phic entanglement entropy of an interval at the cutoff surface. The hologr
aphic entanglement entropy is finite and features a minimum length scale\,
as expected for TTbar-deformed CFTs.\n

DESCRIPTION:Title: Comments on Heavy Operators in N=4 SYM\nby Minkyoo Kim (Soga
ng University) as part of Integrability\, Duality and related topics\n\n\n
Abstract\nFor N=4 SYM in the planar limit\, its spectrum is completely sol
ved at finite coupling through integrability. The dynamics of single-tra
ce operators and worldsheet formulation of holographic dual strings are su
ch cases. On the other hand\, the spectrum of heavy operators\, which is
a holographic dual to giant graviton D-branes\, cannot be restricted to t
he planar limit and therefore is not generally integrable. In this talk\
, I would like to introduce techniques that have been developed to achieve
analytic results in these situations. In particular\, I shall review so
me established ideas based on group representation theory and comment on s
ome new results.\n

DESCRIPTION:Title: Topological gauging and non-relevant deformations of Quantum Fie
ld Theories\nby Stefano Negro (New York University) as part of Integra
bility\, Duality and related topics\n\n\nAbstract\nIn the last few years\,
much attention has been devoted to the study of a peculiar class of irrel
evant deformations of 2-dimensional Quantum Field Theories\, known as “S
olvable Irrelevant Deformations”. The poster child of these is the celeb
rated “TTbar deformation”. They display unusual properties in the UV\,
which can be described exactly\, their irrelevant nature notwithstanding.
For this reason they represent a sensible extension of Quantum Field Theo
ry beyond the Wilsonian paradigm and have attracted a considerable attenti
on from the high energy theory community. The property of being solvable i
s shared with a wider class of deformations\, constructed out of pairs of
conserved currents. In general these are marginal deformations\, thus pres
enting very different UV properties. Nonetheless their structures are simi
lar to the TTbar ones\, hinting at the existence of a universal descriptio
n.\n\nIn this talk I will present a very general framework that accommodat
es both solvable irrelevant and solvable marginal deformations\, which amo
unts to a “topological gauging” of the symmetries of the system. Throu
gh simple path integral computations\, I will recover the main features of
these theories and show their equivalence to TST and Yang-Baxter deformat
ions. For the case of TTbar\, the topological gauging perspective explains
the previously not understood relation to field theory in non-commutative
Minkowski space-time and to the centrally extended Poincaré algebra.\n

I will discuss a new proposal for a classically marginal deformation of an

ensor because it involves a square root\, the resulting flow equation for
the classical Lagrangian has some surprisingly nice properties\, and can b

y John. Z. Imbrie (University of Virginia) as part of Integrability\, Dual
ity and related topics\n\n\nAbstract\nA quantum system is said to be many-
body localized (MBL) if one can find a complete set of local integrals of
motion (LIOMs). This leads to a breakdown of thermalization. I will summar
ize a proof that certain one-dimensional spin chains have an MBL phase (th
e proof depends on a certain assumption on level statistics). In recent wo
rk with Morningstar and Huse\, we develop specific RG flow equations to st
udy the critical phenomenon at the edge of the MBL phase. This turns out
to be similar to the Kosterlitz-Thouless (KT) flow\, but there are importa
nt differences that place the MBL transition in a new universality class.\

DESCRIPTION:Title: Boundary and plane defect criticality in the 3d O(N) model\
nby Max A. Metlitski (MIT) as part of Integrability\, Duality and related
topics\n\n\nAbstract\nIt is known that the classical O(N) model in dimensi
on d > 3 at its bulk critical point admits three boundary universality cla
sses: the ordinary\, the extraordinary and the special. The extraordinary
fixed point corresponds to the bulk transition occurring in the presence o
f an ordered boundary\, while the special fixed point corresponds to a bou
ndary phase transition between the ordinary and the extra-ordinary classes
. While the ordinary fixed point survives in d = 3\, it is less clear what
happens to the extraordinary and special fixed points when d = 3 and N is
greater or equal to 2. I'll show that formally treating N as a continuous
parameter\, there exists a critical value Nc > 2 separating two distinct
regimes. For N < Nc the extra-ordinary fixed point survives in d = 3\, alb
eit in a modified form: the long-range boundary order is lost\, instead\,
the order parameter correlation function decays as a power of log r. For
N > Nc there is no fixed point with order parameter correlations decaying
slower than power law. I'll discuss how these findings compare to recent M
onte-Carlo studies of classical and quantum spin models with SO(3) symmetr
y.\n

DESCRIPTION:Title: Line Operators in Chern-Simons-Matter Theories and Bosonization
in Three Dimensions\nby Deliang Zhong (Tel Aviv University) as part o
f Integrability\, Duality and related topics\n\n\nAbstract\nWe study Chern
-Simons theories at large N with either bosonic or fermionic matter in the
fundamental representation. The most fundamental operators in these theor
ies are mesonic line operators\, the simplest example being Wilson lines e
nding on fundamentals. We classify the conformal line operators along an a
rbitrary smooth path as well as the spectrum of conformal dimensions and t
ransverse spins of their boundary operators at finite 't Hooft coupling. T
hese line operators are shown to satisfy first-order chiral evolution equa
tions\, in which a smooth variation of the path is given by a factorized p
roduct of two line operators. We argue that this equation\, together with
the spectrum of boundary operators\, are sufficient to uniquely determine
the expectation values of these operators. We demonstrate this by bootstra
pping the two-point function of the displacement operator on a straight li
ne. We show that the line operators in the theory of bosons and the theory
of fermions satisfy the same evolution equation and have the same spectru
m of boundary operators.\n

DESCRIPTION:Title: On the classification of UV completions of integrable $T \\ba
r{T}$ deformations of CFT\nby Andre LeClair (Cornell University) as p
art of Integrability\, Duality and related topics\n\n\nAbstract\nIt is wel
l understood that 2d conformal field theory (CFT) perturbed by an irreleva
nt $T\\bar{T}$ perturbation of dimension $4$ has universal properties. \
nIn particular\, for the most interesting cases\, the theory develops a
singularity in the ultra-violet (UV)\, signifying a shortest possible d
istance\, with a Hagedorn transition in applications to string theory.
\nWe show that by adding an infinite number of higher $T\\bar{T}_{s>1}$
irrelevant operators of positive integer scaling dimension $2(s+1)$ with
tuned couplings\, this singularity can be resolved and the theory becom
es UV complete with a Virasoro central charge $c_{UV }> c_{IR}$ consistent
with the c-theorem. \nWe propose an approach to classifying the possibl
e UV completions of a given CFT perturbed by $T\\bar{T}_s$ that are integr
able. \nThe main tool utilized is the thermodynamic Bethe ansatz. \nWe s
tudy this classification for theories with scalar (diagonal) factorizable
S-matrices. For the Ising model with \n$c_{IR} = \\tfrac{1}{2}$ we find
3 UV completions based on a single massless Majorana fermion description
with \n$c_{UV} = \\tfrac{7}{10}$ and $ \\tfrac{3}{2}$\, which both have $
N=1$ SUSY and were previously known\, and we argue that these are the onl
y solutions to our classification problem based on this spectrum of partic
les. We find \n 3 additional ones with a spectrum of 8 massless partic
les related to the Lie group $E_8$ appropriate to a magnetic perturbation\
nwith $c_{UV} = \\tfrac{21}{22} \, \\tfrac{15}{2}$ and $\\tfrac{31}{2}$.
We argue that it is likely there are more cases for this $E_8$ spectrum.
\nWe also study simpler cases based on $\\suthree$ and $\\sufour$ where
we can propose complete classifications. For $\\suthree$ the infra-red
(IR) theory is the 3-state Potts model with $c_{IR} = \\tfrac{4}{5}$ and w
e find 3 completions with $\\tfrac{4}{5} < c_{UV} \\leq \\tfrac{16}{5}$.
For the $\\sufour$ case\, which has $3$ particles and $c_{IR} =1$\,
and we find $11$ UV completions\nwith $1 < \\cUV \\leq 5$\, most of w
hich were previously unknown. (Based on work with Changrim Ann).\n

DESCRIPTION:Title: Near BPS black holes and microstates in supergravity\nby Ma
tthew Heydeman (IAS) as part of Integrability\, Duality and related topics
\n\n\nAbstract\nIt is an open problem to understand the ultimate fate of t
he path integral in gravity and quantum black hole thermodynamics. Recent
progress has focused on supersymmetric black holes in asymptotically AdS s
pacetimes in which the sum over classical BPS solutions reproduces the sup
erconformal index of the dual CFT. In a parallel line of development\, it
has been understood that certain models of 2d gravity describe the near ho
rizon region of a near-extremal black hole. At strong coupling the integra
l over metrics in these models may be done exactly\, and the solution reve
als a coarse-grained chaotic spectrum with no sharply defined microstates.
In this talk\, we will show that these two approaches are compatible an
d compute the low-temperature partition function of near-BPS black holes v
ia a gravitational path integral. Our approach uses an effective field the
ory of the near horizon geometry which reduces to an exactly solvable supe
rsymmetric extension of the Schwarzian theory found in toy models of 2d gr
avity. The quantization of this theory gives a quantum gravitational deriv
ation of the extremal entropy and the superconformal index\, showing that
supergravity at strong coupling may exhibit both exact integrable microsta
tes as well as a chaotic spectrum of near-BPS states. This approach gives
universal predictions which apply to both AdS and flat space black holes a
s well as dual superconformal field theories such as N=4 SYM.\n

for decades. As a result\, we can express 3-point functions and mass-coup

DESCRIPTION:Title: Sailing Past the Edge and Discovering the Island\nby Tarek
Anous (University of Amsterdam) as part of Integrability\, Duality and rel

us to rethink the very meaning of microscopic entropy in the presence of d
ynamical gravity. I will present some work elucidating how the island/QES
prescription emerges in a simple doubly holographic setup where we have an
alytic control. We will consider two holographic 2d CFTs joined at an inte
rface such that the bulk dual is a geometry that interpolates between two
locally 3d AdS geometries with different AdS lengths. In particular we wi
ll consider systems where the transition region is a thin brane with tensi
on T. In the limit of large tension\, the brane gets pushed outward toward
s the boundary\, meaning the effective theory on the brane is conformal an
d gravity almost decouples. We show precisely how the canonical CFT entrop
y and the remaining gravity dynamics leads to an island formula in this se
tup. The location of the island is identified with where the RT surface cr
osses the brane in the full holographic 3d picture.\n

DESCRIPTION:Title: Bootstrapping the Ising model on the lattice\nby Minjae Cho
(Princeton University) as part of Integrability\, Duality and related top
ics\n\n\nAbstract\nWe discuss a bootstrap approach to the statistical Isin
g model of spins on the infinite lattice\, where spin-flip equations and p
ositivity conditions such as reflection positivity and Griffiths inequalit
ies lead to rigorous two-sided bounds on spin correlators.\n
