DESCRIPTION:Speakers: Mr. UEBA\, Inori (Kobe University)\nWe have found th
at the N-extended quantum mechanical supersymmetry with central charges is
hidden in the 4D mass spectrum of higher dimensional Dirac field. The sup
ercharges tell us a relationship among the Kaluza-klain (KK) mode function
s with degenerate 4D mass eigenvalues due to the degrees of freedom of the
higher dimensional spinor. Furthermore\, we focus on the BPS states which
form the short multiplets.\n\nhttps://conference-indico.kek.jp:443/indico

DESCRIPTION:Speakers: Mr. YAN\, Han (Okinawa Institute of Science and Tech
nology)\nWe propose that the fracton topological order is a class of toy m
odels for holography. The discovery of AdS/CFT correspondence as a concret
e construction of holography\, and the subsequent developments including t
he Ryu-Takanayagi formula of entanglement entropy have revolutionized our
understanding of quantum gravity\, and provided a powerful tool set for so
lving various strongly-coupled quantum field theory problems. To resolve m
any of the mysteries of holography\, toy models can be very helpful. One e
xample is the holographic tensor-network constructions which illuminate th
e quantum error-correcting properties of gravity in AdS space. In this wor
k we discuss a classical toy model based on fracton topological order\, a
class of exotic many-body systems with boundary area law of ground state d
egeneracy and (partially) immobile excitations. We show that such a model
defined on the hyperbolic lattice satisfies some key properties of hologra
phic correspondence. These properties include: the AdS-Rindler reconstruct
ion is realized\; the mutual information obeys the Ryu-Takayanagi formula\
, and a naively defined black hole's entropy scales as its horizon area. W
e end with an outlook of how fracton model may be used to concretely demon
strate the quantum-error correction encoding procedure of toy models for g
ravity.\n\nhttps://conference-indico.kek.jp:443/indico/event/48/session/11

Dirac operator on the noncommutative torus\, which is consistent with IKKT
model\, based on noncommutative geometry. In addition\, we consider zero-

ro-mode solutions have chirality and generation structures similar to the
commutative case. Moreover\, we compute normalization factors of the zero-

DESCRIPTION:Speakers: Prof. SATO\, Matsuo (Hirosaki University)\nPerturbat
ive string amplitudes are correctly derived from the string geometry theor
y\, which is one of the candidates of a non-perturbative formulation of st
ring theory. In order to derive non-perturbative effects rather easily fro
m the theory\, we formulate topological string geometry theory\, which is
obtained by restricting the string geometry theory to its topological sect
or. Because string geometry is described by a superfield formalism\, we fi
rst describe the topological string theory in a superfield formalism. By c
onstructing a string geometry based on this superfield formalism\, we form
ulate the topological string geometry theory. We derive the perturbative p
artition function of the topological string theory from fluctuations aroun
d a classical solution in the topological string geometry theory. We will
discuss how to derive non-perturbative corrections on the partition functi

DESCRIPTION:Speakers: Dr. WATANABE\, Kento (University of Tokyo)\nWe explo
re a C-theorem in defect conformal field theories (DCFT) that unify all th
e known conjectures and theorems until now. We examine as a candidate C-fu
nction the additional contributions from conformal defects to the sphere f
ree energy and the entanglement entropy across a sphere in a number of exa
mples including holographic models. We find the two quantities are equival
ent\, when suitably regularized\, for codimension-one defects (or boundari
es)\, but differ by a universal constant term otherwise. Moreover\, we fin
d in a few field theoretic examples that the sphere free energy decreases
but the entanglement entropy increases along a certain renormalization gro
up (RG) flow triggered by a defect localized perturbation which is assumed
to have a trivial IR fixed point without defects. We hence propose a C-th
eorem in DCFTs stating that the increment of the regularized sphere free e
nergy due to the defect does not increase under any defect RG flow. We als
o provide a proof of our proposal in several holographic models of defect
RG flows. (Ref: 1810.06995[hep-th])\n\nhttps://conference-indico.kek.jp:44

DESCRIPTION:Speakers: YOKOKURA\, Ryo (Keio U.)\nWe investigate three-form
gauge theories with higher derivative interactions and their supersymmetri
c extensions in four space-time dimensions. For the bosonic three-form gau
ge theories\, we show that derivatives on the field strength of the 3-form
gauge field yield a tachyon as far as the Lagrangian contains a quadratic
kinetic term\, while such the term with opposite sign gives rise to a gho
st. We confirm that there is neither a tachyon nor a ghost when all higher
derivative terms are given by functions of the field strength. For this g
host/tachyon-free Lagrangian\, we determine the boundary term necessary fo
r the consistency between the equation of motion and energy-momentum tenso
r. For supersymmetric extensions\, we present ghost/tachyon-free higher de
rivative interactions of arbitrary order of the field strength and corresp
onding boundary terms as well.\n\nhttps://conference-indico.kek.jp:443/ind

DESCRIPTION:Speakers: Dr. SHIBA\, Noburo (KEK)\nIn the expanding universe\
, two interacting fields are no longer in thermal contact when the interac
tion rate becomes smaller than the Hubble expansion rate. After decoupling
\, two subsystems are usually treated separately in accordance with equili
brium thermodynamics and the thermodynamic entropy gives a fiducial quanti
ty conserved in each subsystem. In this paper\, we discuss a correction to
this paradigm from quantum entanglement of two coupled fields. The thermo
dynamic entropy is generalized to the entanglement entropy. We formulate a
perturbation theory to derive the entanglement entropy and present Feynma
n rules in diagrammatic calculations. For specific models to illustrate ou
r formulation\, an interacting scalar-scalar system\, quantum electrodynam
ics\, and the Yukawa theory are considered. We calculate the entanglement
entropy in these models and find a quantum correction to the thermodynamic
entropy. The correction is revealed to be important in circumstances of i
nstantaneous decoupling.\n\nhttps://conference-indico.kek.jp:443/indico/ev

DESCRIPTION:Speakers: Dr. NOZAKI\, Masahiro (RIKEN)\nWe study operator ent
anglement measures of the unitary evolution operators of (1+1)-dimensional
conformal field theories\, aiming to uncover scrambling and chaotic behav
iors thereof. In particular\, we compute the bi-partite and tri-partite mu
tual in- formation for various configurations of input and output subsyste
ms\, and as a function of time. We contrast three different conformal fiel
d theories: the free fermion the- ory\, compactified free boson theory at
various radii\, and conformal field theories with holographic dual. We fou
nd that the bi-partite mutual information exhibits distinct behaviors for
these different conformal field theories\, reflecting the different inform
a- tion scrambling abilities of these unitary operators\; while a quasi-pa
rticle picture can describe well the case of the free fermion and free bos
on conformal field theories\, it completely fails for the case of holograp
hic conformal field theories. Similarly\, the tripartite mutual informatio
n also distinguishes the unitary evolution operators of dif- ferent confor
mal field theories. In particular\, the late time behaviors of the tripart
ite mutual information\, when the output subsystems are semi-infinite\, ar
e quite distinct for the free fermion conformal field theory\, the free bo
son theory at different compacti- fication radii\, and holographic conform
al field theories. We speculate that the late time saturation value of the
tripartite information for holographic conformal field theories saturates
the lower bound of the negativity of the tripartite mutual information.\n

DESCRIPTION:Speakers: Dr. ASANO\, Yuhma (KEK)\nAn idea to formulate string
theory or M-theory by a gauge theory attracts theorists and has been exte
nsively studied. The gauge theory should be lower dimensional so that a ge
ometry in string or M-theory\, which has higher dimensions\, must emerge f
rom it. This suggests that there would be a phase transition in the gauge
theory and that the geometry should appear as its temperature decreases. I
n this talk\, I will explain the BMN matrix model\, a gauge theory conside
red as a non-perturbative formulation of M-theory on the plane-wave geomet
ry. This theory has infinitely many vacua and each of them corresponds to
one of bubbling geometries in the type IIA supergravity. Gauge-theory comp
utation showed that a certain BPS operator reproduced the geometries on th
e gravity side and also brane geometries in the M-brane picture. At finite
temperatures\, these geometries should be realised in a non-trivial way\,
an example of which is a phase transition regarding a black hole---the co
nfinement/deconfinement transition. Recently\, the gravity solution corres
ponding to the thermal BMN model around the trivial vacuum was numerically
obtained so that the critical temperature of the deconfinement transition
was computed. I will show recent results of Monte Carlo simulations of th
e gauge-theory side\, which revealed two types of phase transition\, consi
stent with the gravity prediction.\n\nhttps://conference-indico.kek.jp:443

We study the dynamics of an open string in the D4-soliton geometry which c

that the interquark force in 4d large Nc QCD is chaotic\, and we evaluate

zy spaces are known as a typical example of noncommutative geometry and ex

mechanism to describe gravity in the framework of fuzzy spaces remains to
be completely elucidated. In order to understand the mechanism\, we focus
on the notion of diffeomorphisms\, which plays a key role in the classical
theory of gravity. In this talk\, we propose a formulation of the diffeom
orphisms for fuzzy spaces in terms of the Berezin-Toeplitz quantization ma
p\, which is introduced in the context of geometric quantization. We apply
this formulation to 2-sphere as an example and obtain new matrix configur
ations that are diffeomorphic to the standard fuzzy sphere given by the ge
nerators of SU(2) Lie algebra.\n\nhttps://conference-indico.kek.jp:443/ind

ariant momentum-cutoff regularization. We study one or two supermultiplets
with various superpotentials. From a two-point correlation function in th
e IR region\, we measure the central charge\, which is consistent with the
conjectured LG description of the ADE minimal models. Our result supports
the theoretical conjecture and\, at the same time\, indicates a possible
computational method of correlation functions in the $\\mathcal{N}=2$ SCFT
from the LG description.\n\nhttps://conference-indico.kek.jp:443/indico/e

DESCRIPTION:Speakers: Mr. KUBO\, Naotaka (Yukawa Institute for Theoretical
Physics)\nIt was known that quantum curves and super Chern-Simons matrix
models correspond to each other. From the viewpoint of symmetry\, the alge
braic curve of genus one\, called the del Pezzo geometry\, enjoys symmetri
es of the exceptional algebra\, while the super Chern-Simons matrix model
is described by the free energy of topological strings on the del Pezzo ba
ckground with the symmetry broken. We study the symmetry breaking of the q
uantum cousin of the algebraic curve and find that the symmetry breaking r
eproduces the results in the super Chern-Simons matrix models.\n\nhttps://

localization mechanism of gauge fields on a 3-brane in Yang-Mills-Higgs m
odels with a modified kinetic term of gauge fields in non-compact extra di
mensions (D>4). The localization mechanism is carried out when the Higgs f
ield locally condenses on the 3-brane. Hence\, the Higgs mechanism yields\
, in addition to two conventional roles (spontaneous symmetry breaking of
the gauge symmetry and generating mass for chiral fermions)\, a new impo
rtant consequence\, namely\, localization of the gauge fields on a 3-brane
. The lightest localized gauge field is massless (massive) if the Higgs fi
eld is neutral (charged) to the gauge field.\n\nhttps://conference-indico.

DESCRIPTION:Speakers: Prof. YOSHIDA\, Kentaroh ()\nRecently\, there has be
en a fundamental and significant development in the Green-Schwarz (GS) for
mulation of superstring theory. In this formulation\, the kappa-symmetry p
lays a central role to ensure the consistency of the theory. In 2016\, Tse
ytlin and Wulff showed that the kappa-symmetry constraints of the GS super
string defined on an arbitrary background lead to a ``generalized'' superg
ravity\, which contains an additional (non-dynamical) vector field\, rathe
r than the standard supergravity. This result indicates that we might have
overlooked a potentially important ingredient in the low-energy effective
theory of string theory for long time\, and may open up new directions in
cluding phenomenology and cosmology.\n\nIn this talk\, I will introduce wh
at is the generalized supergravity and then discuss Weyl invariance of str

holographic entanglement of purification agrees with the entanglement ent
ropy in a conformal field theory for a purified state obtained from a spec
ial Weyl transformation\, called path-integral optimizations. In other wor
ds\, this special purified state has the minimal path-integral complexity.

DESCRIPTION:Speakers: Mr. LEUNG\, Hon Yin (Waseda University)\nO(α') corr
ections in 10D heterotic supergravity are known to give nontrivial contrib

tor ansatz that is valid only for geometries of 2 complex (4 real) dimensi
ons\, we obtained a closed expression for the metric correction in the cas
e of several orbifold limits of K3\, namely T^4/Z_n where n=2\,3\,4\,6. Fu
rthermore\, we numerically investigated the behaviour around these orbifol
d fixed points by considering the metric correction on the resolution of a
C^2/Z_2 singularity. It was demonstrated that in the blow-down limit of t
he resolution\, we regain the same behaviour as given by the closed form e
xpression for the orbifold limits of K3\, showing that the numerical resul
ts are valid. Further prospects of utilising these O(α') corrected metric
as a novel approach in obtaining realistic or semi-realistic Yukawa coupl

DESCRIPTION:Speakers: Dr. ISONO\, Hiroshi (Chulalongkorn University)\nWe c
onstruct a crossing symmetric basis for conformal four-point functions in
momentum space by requiring consistent factorization. Just as scattering a
mplitudes factorize when the intermediate particle is on-shell\, non-analy
tic parts of conformal correlators enjoy a similar factorization in moment
um space. Based on this property\, Polyakov\, in his pioneering 1974 work\
, introduced a basis for conformal correlators which manifestly satisfies
the crossing symmetry. He then initiated the bootstrap program by requirin
g its consistency with the operator product expansion. This approach is co
mplementary to the ordinary bootstrap program\, which is based on the conf
ormal block and requires the crossing symmetry as a consistency condition
of the theory. Even though Polyakov's original bootstrap approach has been
revisited recently\, the crossing symmetric basis has not been constructe
d explicitly in momentum space. In this poster talk we show the complete t
he construction of the crossing symmetric basis for scalar four-point func
tions with an intermediate operator with a general spin\, by using new ana
lytic expressions for three-point functions involving one tensor. Our new
basis manifests the analytic properties of conformal correlators. Also the
connected and disconnected correlators are manifestly separated\, so that
it will be useful for the study of large N CFTs in particular.\n\nhttps:/

irst show that an induced metric defined from the flowed field generally c
orresponds to the quantum information metric\, called the Bures or Helstro
m metric\, if the flowed field is normalized appropriately. I next verify
that the induced metric computed explicitly with the free flow equation al
ways becomes the AdS metric when the theory is conformal. I also show that
the conformal symmetry in $d$ dimensions converts to the AdS isometry in
$d+1$ dimensions after $d$ dimensional quantum averaging. This guarantees
the emergence of AdS geometry without explicit calculation. I finally disc
uss several extensions of this method including the latest results.\n\nhtt

omplex structure moduli and the axion-dilaton system are stabilised in the

corrections\, together with internal magnetic fields along the D7-branes w
orld-volume leading to Fayet-Iliopoulos D-terms in the effective supergrav

classical solutions of type IIB matrix model that generate chiral fermion
s\, which is essential for realizing the Standard Model. In particular\, w
e consider solutions constructed from representations of special unitary g
roups' generators. Fermion wave functions can then be generated as eigenve
ctors of the associated matrix Dirac operator. It is found that many solut
ions give large number of exact zero modes. However\, only zero modes that
are localized can be interpreted as fermions at brane intersections. We c
an optimize the localization by mixing these zero modes together. Finally\
, we report some solutions and number of the associated localized chiral z
ero modes.\n\nhttps://conference-indico.kek.jp:443/indico/event/48/session

DESCRIPTION:Speakers: Dr. TERADA\, Takahiro (KEK)\nIn supersymmetric theor
ies\, the signs of quartic terms in the Kähler\npotential control the sta
bility of non-supersymmetric field\nconfigurations. In particular\, in su
persymmetric inflation models\,\nthe signs are important for the stability
of an inflationary\ntrajectory as well as for the prediction of the spect
ral index. In\nthis paper\, we clarify what properties of a UV theory det
ermine the\nsign from unitarity arguments of scattering amplitudes. As\nn
on-trivial examples\, we discuss the sign of a four-meson term in\nlarge N
supersymmetric gauge theories and also those of the quartic\nterms obtain
ed in the intersecting D-brane models in superstring\ntheory. The UV orig
ins of inflationary models and supersymmetry\nbreaking models are constrai
ned by this discussion.\n\nhttps://conference-indico.kek.jp:443/indico/eve

DESCRIPTION:Speakers: Dr. ZHANG\, Yun-Long (YITP)\nWe discuss a scenario t
hat the dark matter fluid in late time universe emerges as part of the hol
ographic stress-energy tensor on the hypersurface in higher dimensional fl
at spacetime. We construct a toy model with the Friedmann-Lemaitre-Roberts
on-Walker (FLRW) hypersurface as the holographic screen in the flat bulk.
After adding the baryonic matter on the screen\, we assume that both of th
e dark matter and dark energy can be described by the Brown-York stress-en
ergy tensor. From the Hamiltonian constraint equation in the flat bulk\, w
e find an interesting relation between the dark matter and baryonic matter
's energy density parameters\, by comparing with the Lambda cold dark matt
er parameterization. We further compare this holographic embedding of emer
gent dark matter with traditional braneworld scenario and present an alter
native interpretation as the holographic universe\, with the new parameter
ization of the Friedmann equation. \n[Ref: JHEP 1810 (2018) 009 [arXiv: 17

DESCRIPTION:Speakers: Dr. BHADANE\, Mahesh Sakharam (DEPARTMENT OF PHYSICS
\, SPPU)\nNeutron detectors are vital devices used in various fields like
nuclear power\, nuclear medicine\, particle physics\, etc. In the present
work\, pure europium oxide (Eu2O3) shows the remarkable results for therma
l neutron detection. The natural thermal neutron source Cf-252 having flux
106 n/sec/cm2 was used for irradiation of Eu2O3 samples. All the thermal
neutron fluences were measured in ex-situ time [1-3]. For the structural c
onfirmation\, the samples were characterized by using XRD and from the dat
a it was observed that the intensity of the characteristics peaks decrease
d with the increase in the neutron fluence. Moreover\, thermal neutron dos
imetric characteristics of the present phosphor\, such as thermoluminescen
ce glow curve\, TL dose–response\, fading\, repeatability have been stud
ied. This phosphor powder represents a deeper level dosimetric trap\, whic
h provides the TL glow peak around 303 oC. The TL response of Eu2O3 phosph
or as a function of thermal neutron fluence is observed to be very linear
up to the fluence of 1.55 X 1011 n/cm2 and then saturates with further inc
rease in the fluence. In addition\, the TL glow curves were deconvoluted b
y glow curve deconvolution (GCD) method and corresponding trapping paramet
ers have been determined. It has been found that for every deconvoluted pe
ak there is a specific level of energy trapping. The europium oxide phosph
or has been used effectively for the neutron dosimetric application.\n\nht

DESCRIPTION:Speakers: Mr. AOKI\, Toshihiro (SOKENDAI)\nThe type IIB matrix
model was proposed as a non-perturbative formulation of superstring theor
y in 1997. The emergence of (3+1)-dimensional space-time was observed in M
onte Carlo studies of its Lorentzian version. This implies that an expandi
ng (3+1)-dimensional space-time naturally appears from (9+1)-dimensional s
pace-time\, in which superstring theory is defined. The expanding behavior
was studied by simulating simplified versions of the model\, which sugges
ted that the expansion is exponential at the beginning\, and it turns into
a power law at later times. This property is reminiscent of the inflation
and the FRW universe\, respectively. In this work we investigate the spac
e-time structure of the matrix configurations obtained in the simulation\,
and find that the expanding 3d space is described essentially by the Paul
i \nmatrices. We attribute this problem to an approximation\, which is use
d\nto avoid the sign problem in Monte Carlo simulation\, and discuss the\n
possibility of obtaining a regular space-time if we investigate the\norigi
nal model without such an approximation.\n\nhttps://conference-indico.kek.

of these winding corrections in gauged linear sigma model. Our analysis re
veals that for every supergravity solution\, one has DFT solutions that in
clude string winding corrections. This presentation is based on JHEP07(201
