DESCRIPTION:Title: Pushing boundaries in holography\nby Mark van Raamsdonk
(UBC) as part of GQFI Seminars\n\n\nAbstract\nIn this talk\, I'll discuss
a variety of applications in AdS/CFT that make use of CFTs living on spac
etimes with boundaries. The applications include the construction of black
hole microstates whose behind-the-horizon geometries can be understood ex
plicitly\, constructing models of evaporating black holes in which the Pag
e curve can be understood through explicit CFT calculations\, providing a
microscopic descriptions of certain Randall-Sundrum scenarios\, and provid
ing a framework for holography where the CFT is replaced by a large number
of non-interacting "bits".\n\nYou can access the recording right here: ht

DESCRIPTION:Title: Stress Tensor Sector of Conformal Correlators\nby Manue
la Kulaxizi (Trinity College Dublin) as part of GQFI Seminars\n\n\nAbstrac
t\nAn important part of a CFT four-point function\, the stress tensor sect
or\, comprises the exchanges of the stress tensor and its composites. The
OPE coefficients of these multi-stress tensor operators and consequently\,
the complete stress tensor sector of four-point functions in CFTs with a
large central charge\, can be determined by computing a heavy-heavy-light-
light correlator. We show how one can make substantial progress in this di
rection by bootstrapping a certain Ansatz for the stress tensor sector of
the correlator\, iteratively computing the OPE coefficients of multi-stres
s tensor operators with increasing twist. Some parameters are not fixed by
the bootstrap - they correspond to the OPE coefficients of multi-stress t
ensors with spin zero and two. We further show that in holographic CFTs on
e can use the phase shift computed in the dual gravitational theory to red
uce the set of undetermined parameters to the OPE coefficients of multi-st
ress tensors with spin zero. Finally\, we verify some of these results usi
ng the Lorentzian OPE inversion formula and comment on its regime of appli
cability.\n\nCorrect link: https://mpi-aei.zoom.us/j/96444244925.\n

DESCRIPTION:Title: Toward a 3d Ising Model with a weakly coupled string du
al\nby Nabil Iqbal (Durham) as part of GQFI Seminars\n\n\nAbstract\nIt has
long been expected that the 3d Ising model can be thought of as a string
theory\, where one interprets the domain walls that separate up spins from
down spins as two-dimensional string worldsheets. I will revisit this 'st
ring theory' from the modern point of view of higher form symmetries. The
usual Ising Hamiltonian measures the area of these domain walls\; as there
is no explicit dependence on the genus of the domain walls\, it can be th
ought of as a string theory with string coupling equal to unity. I discuss
how to add new local terms to the Ising Hamiltonian that further weight e
ach spin configuration by a factor depending on the genus of the correspon
ding domain wall\, resulting in a new 3d Ising model that has a tunable ba
re string coupling. I will use a combination of analytical and numerical m
ethods to analyze the phase structure of this model as this string couplin
g is varied. I will also describe statistical properties of the topology o
f worldsheets and speculate on the prospects of using this new deformation
at weak string coupling to find a worldsheet description of the 3d Ising
transition.\n\nZoom link: https://mpi-aei.zoom.us/j/91981837516 .\n\n1) Pl

DESCRIPTION:Title: Models of quantum complexity growth\nby Nick Hunter-Jon
es (IQI\, Perimeter) as part of GQFI Seminars\n\n\nAbstract\nAbstract: The
quantum complexity of a unitary or state is defined as the size of the sh
ortest quantum computation that implements the unitary or prepares the sta
te. The notion has far-reaching implications spanning computer science\, q
uantum many-body physics\, and high energy theory. Complexity growth in ti
me is a phenomenon expected to occur in holographic theories and strongly-
interacting many-body systems more generally\, but explicitly computing th
e complexity of a given state or unitary is notoriously difficult. By cons
idering an ensemble of systems\, and establishing a rigorous relation betw
een complexity and unitary designs\, we will prove statements about comple
xity growth in various models. Specifically\, we prove a linear growth of
complexity in random quantum circuits\, using a recent result about their
design growth. \n\nZoom Link: https://mpi-aei.zoom.us/j/99064635917\n\n---

y Ki-Seok Kim (POSTECH\, Pohang) as part of GQFI Seminars\n\n\nAbstract\nH
olographic duality conjecture states that a D-dimensional quantum field th
eory can be duality-mapped into a (D+1)-dimensional quantum gravity theory
\, where the quantum gravity theory is a “hologram” of the quantum fie
ld theory. Although this holographic duality conjecture serves as a novel
non-perturbative theoretical framework for strongly coupled quantum field
theories\, the duality transformation has not been clarified until now. In
this study we propose a prescription for the holographic duality transfor
mation based on Wilsonian recursive renormalization group (RG) transformat
ions. As a result\, we manifest the RG flow of an effective field theory w
ith the introduction of an emergent extra dimensional space\, where RG $\\
beta$-functions to describe the evolution of coupling functions appear in
the resulting effective action explicitly through the extra dimensional sp
ace. This microscopic construction of the dual holographic mapping suggest
s that the origin of non-perturbative physics is in intertwined renormaliz
ation between dynamics and geometry.\n\n-----\n\n1) Please display your na

DESCRIPTION:Title: Geometric secret sharing in a model of Hawking radiatio
n\nby Arjun Kar (University of Pennsylvania) as part of GQFI Seminars\n\n\
nAbstract\nWe consider a black hole in three dimensional AdS space entangl
ed with an auxiliary radiation system. We model the microstates of the bla
ck hole in terms of a field theory living on an end of the world brane beh
ind the horizon\, and allow this field theory to itself have a holographic
dual geometry. This geometry is also a black hole since entanglement of t
he microstates with the radiation leaves them in a mixed state. This "ince
ption black hole" can be purified by entanglement through a wormhole with
an auxiliary system which is naturally identified with the external radiat
ion\, giving a realization of the ER=EPR scenario. In this context\, we pr
opose an extension of the Ryu-Takayanagi (RT) formula\, in which extremal
surfaces computing entanglement entropy are allowed to pass through the br
ane into its dual geometry. This new rule reproduces the Page curve for ev
aporating black holes\, consistently with the recently proposed "island fo
rmula". We then separate the radiation system into pieces. Our extended RT
rule shows that the entanglement wedge of the union of radiation subsyste
ms covers the black hole interior at late times\, but the union of entangl
ement wedges of the subsystems may not. This result points to a secret sha
ring scheme in Hawking radiation wherein reconstruction of certain regions
in the interior is impossible with any subsystem of the radiation\, but p
ossible with all of it.\n\n-----\n\n1) Please display your name when you j

nt entropies in pure JT gravity\, including all of the perturbative gravit
on corrections. I will also explain why it is not possible to factorize th
e gravity Hilbert space in a local way. The tension between defining a loc
al and isometric factorization map motivates the insertion of a "defect op
erator" into the standard definition of the Renyi entropy. The defect oper
ator has a clear interpretation in the Euclidean replica calculation of th
e entropy. The contribution of the defect operator to the entanglement ent
ropy matches the area term in the quantum Ryu-Takayanagi formula.\n\n-----

ptotically flat two-dimensional dilaton gravity coupled to a conformal fie

information flux as given by the entanglement entropy show that it follows
the Hawking curve\, indicating that information is destroyed in these mod
els. Recently\, motivated by developments in AdS/CFT\, a semiclassical isl
and rule for entropy has been proposed. We define and compute the island r

del of dilaton gravity and show that\, in contrast\, it follows the unitar

DESCRIPTION:Title: Complexity measures from geometric actions on Virasoro
coadjoint orbits\nby Marius Gerbershagen (Wuerzburg University) as part of
GQFI Seminars\n\n\nAbstract\nWe explore connections between computational
complexity in CFTs\, geometric actions on coadjoint orbits of the Virasor
o group and Liouville theory. Previously\, it was shown in [arXiv:1807.044
22] that by choosing a suitable cost function\, the resulting complexity f
unctional is equivalent to a geometric action\, up to a term that originat
es from the central extension. We show that this term can be recovered by
modifying the cost function\, making the equivalence exact. We then determ
ine the optimal circuits for these complexity measures and calculate the c
orresponding costs. We find that in most cases the complexity only measure
s the cost associated to phase changes\, while assigning zero cost to the
non-phase changing part of the transformation. Furthermore\, we briefly re
view how geometric actions arise from the gravity theory and derive an equ
ivalence between the sum of two geometric actions and Liouville theory. Fr
om this equivalence statement\, we obtain a mapping of optimal circuits fr
om the path integral optimization approach and from our complexity proposa
l.\n\n1) Please display your name when you join the seminar.\n\n2) Your mi

DESCRIPTION:Title: Entropic order parameters for the phases of QFT\nby Hor
acio Casini (Centro Atomico Bariloche) as part of GQFI Seminars\n\n\nAbstr
act\nWe propose entropic order parameters that capture the physics of gene
ralized symmetries and phases in QFT's. We do so by an analysis of simple
properties (additivity and Haag duality) of the net of operator algebras a
ttached to space-time regions. We observe that different types of symmetri
es are associated with the breaking of these properties in regions of diff
erent non-trivial topologies. When such topologies are connected\, we show
the non locally generated operators generate an Abelian symmetry group\,
and their commutation relations are fixed. The existence of order paramete
rs with area law\, like the Wilson loop for the confinement phase\, or the
't Hooft loop for the dual Higgs phase\, is shown to imply the existence
of more than one possible choice of algebras for the same underlying theor
y. A natural entropic order parameter arises by this non-uniqueness. We di
splay aspects of the phases of theories with generalized symmetries in ter
ms of these entropic order parameters. In particular\, the connection betw
een constant and area laws for dual order and disorder parameters is trans
parent in this approach\, new constraints arising from conformal symmetry
are revealed\, and the algebraic origin of the Dirac quantization conditio
n (and generalizations thereof) is described. A novel tool in this approac
h is the entropic certainty relation satisfied by the dual relative entrop
ies associated with complementary regions\, which quantitatively relates t
he statistics of order and disorder parameters.\n\n1) Please display your
