DESCRIPTION:Speakers: Gota Tanaka (Shizuoka University)\nWe study higher d
erivative extension of the functional renormalization group (FRG).We consi
der the general form of the FRG equations for a scalar field that include
higher functional derivatives with respect to the field. We show that the
epsilon expansion around the Wilson-Fisher fixed point is indeed reproduce
d by the local potential approximation of the general FRG equations.\n\nht

DESCRIPTION:Speakers: Kaiwen Sun (KIAS)\nIn 1992 Wirthmuller showed that f
or any root system of type A\,B\,C\,D\,G\,F and E6\,E7\, the ring of weak
Jacobi forms invariant under Weyl group is a polynomial algebra. However\,
it has recently been proved that for E8 the ring is not a polynomial alge
bra. I will present how to describe E8 Weyl invariant Jacobi forms properl
y\, both weak and holomorphic\, and also how to used them in the modular b
ootstrap of elliptic genera of E-strings. For example\, we prove that for
any Weyl invariant E8 Jacobi form \\phi_t of index t the function E4^[t/5]
\\Delta^[5t/6]\\phi_t can be expressed uniquely as a polynomial in E4\, E6
and Sakai's nine Ai\, Bj forms. This is based on a joint work with Haowu
Wang arXiv:2109.10578.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/80/con

to the pp-wave background. Recently\, we proposed a novel entry of the pp-
wave holographic dictionary\, which equated the Berenstein-Maldacena-Nasta
se (BMN) two-point functions in free Yang-Mills theory with the norm squar
es of the quantum unitary transition amplitudes between the corresponding
tensionless strings in the infinite curvature limit. If our proposal is co
rrect\, it would not only provide first examples of systematic calculation
s of the higher genus critical superstring amplitudes\, but may also in pr

DESCRIPTION:Speakers: Jun-Bao Wu (Tianjin University)\nWe study correlatio
n functions of D-branes and a supergravity mode in AdS\, which are dual to
structure constants of two sub-determinant operators with large charge an
d a BPS single-trace operator. Our approach is inspired by the large charg
e expansion of CFT and resolves puzzles and confusions in the literature o
n the holographic computation of correlation functions of heavy operators.
In particular\, we point out two important effects which are often missed
in the literature\; the first one is an average over classical configurat
ions of the heavy state\, which physically amounts to projecting the state
to an eigenstate of quantum numbers. The second one is the contribution f
rom wave functions of the heavy state. To demonstrate the power of the met
hod\, we first analyze the three-point functions in N=4 super Yang-Mills a
nd reproduce the results in field theory from holography\, including the c
ases for which the previous holographic computation gives incorrect answer
s. We then apply it to ABJM theory and make solid predictions at strong co
upling. Finally we comment on possible applications to states dual to blac
k holes and fuzzballs. This talk is based on work done with Peihe Yang\, Y
unfeng Jiang and Shota Komatsu.\n\nhttps://indico.nitep.osaka-cu.ac.jp/eve

DESCRIPTION:Speakers: Shun'ya Mizoguchi (KEK)\nA conifold is a singular Ca
labi-Yau 3-fold of the simplest type\, and has played important roles in v
arious aspects of string theory. In fact\, in F-theory\, conifold singular
ities are quite commonplace\; conifold singularities typically appear\, in
“split models”\, in most places where charged matter is generated. We
show that the split/non-split transition is\, except in certain exception
al cases\, a conifold transition from the resolved to the deformed side\,
associated with the conifold singularities emerging where the codimension-
one singularity is enhanced to D_{2k+2} (k ≥ 1) or E_7. This clarifies t
he origin of nonlocal matter in the non-split models\, which has been a my
stery for many years.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/80/cont

order ordinary differential equation (ODE) with polynomial potential whic
h is obtained by the Nekrasov-Shatashvili limit of $(A_r\, A_N)$ Argyres-D
ouglas theory in Omega background. We derive the thermodynamic Bethe ansat
z (TBA) equations governing the exact WKB periods\, which provides a gener
alization of the ODE/IM correspondence. Varying the moduli space parameter
s of the potential\, one observes the wall-crossing of the TBA equations.
When the potential is monomimal type\, we show the TBA equations obtained
from the $(A_2\, A_2)$ and $(A_2\, A_3)$-type ODE lead to the $D_4$ and $E
_6$-type TBA equations respectively. This talk is based on the work (hep-t

hree-body effective potential at the 2nd Post-Minkowskian order. At order
2PM a formal result is given in terms of a differential operator acting on
the maximal generalized cut of the one-loop triangle integral. We perform
the PN expansion unambiguously at the level of the integrand. Finding agr
eement with the 2PN three-body potential after integration\, we explicitly
present new G^2 v^4-contributions at order 3PN and outline the generaliza
tion to G^2 v^{2n}. The integrals that represent the essential input for t
hese results respect a non-local Yangian symmetry and are obtained by appl
ying the recent bootstrapping method directly to their ε-expansion around
three dimensions. The coordinate space Yangian generator that we employ t
o obtain these integrals can be understood as a special conformal symmetry
in a dual momentum space. If time permits\, I will also talk about our wo

symmetry defect in 4D lattice pure Z2 gauge theory. In this talk\, we will
describe the junction that occurs where the two defects overlap. The dual

extension to a manifold with boundary\, is physicist-unfriendly\, in that
it is formulated with a nonlocal boundary condition. Recently we (3 physi

from the domain-wall fermion Dirac operator. Our theorem indicates that th
e index can be expressed without any nonlocal conditions\, in such a physi
cist-friendly way that application to the lattice gauge theory is straight
forward. The domain-wall fermion provides a natural mathematical foundatio
n for understanding the bulk-edge correspondence of the anomaly inflow.\n\

DESCRIPTION:Speakers: Shan-Chi Huang (Nagoya U)\nWe study dynamics of mult
i-soliton solutions of anti-self-dual Yang-Mills equations for G = GL(2\,
C) in four-dimensional spaces. The one-soliton solution can be interpreted
as a codimension-one soliton in four-dimensional spaces because the princ
ipal peak of action density localizes on a three-dimensional hyperplane. W
e call it the soliton wall. We prove that in the asymptotic region\, the n
-soliton solution possesses n isolated localized lumps of action density\,
and interpret it as n intersecting soliton walls. More precisely\, each a
ction density lump is essentially the same as a soliton wall because it pr
eserves its shape and ""velocity"" except for a position shift of principa
l peak in the scattering process. The position shift results from the nonl
inear interactions of the multi-solitons and is called the phase shift. We
calculate the phase shift factors explicitly and find that the action den
sities can be real-valued in three kind of signatures. Finally\, we show t
hat the gauge group can be G = SU(2) in the Ultrahyperbolic space U (the s
plit signature (+\,+\,-\,-). This implies that the intersecting soliton wa
lls could be realized in all region in N=2 string theories. It is remarkab
le that quasideterminants dramatically simplify the calculations and proof
s.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/80/contributions/71/

the boundary of the subspace Hp+1 which correspond to the types of conform

DESCRIPTION:Speakers: Yong Zhang (Perimeter institute)\nOne-loop scatterin
g amplitudes in string theories involve configuration-space integrals over
genus-one surfaces with coefficients of Kronecker-Eisenstein series in th

tegration by parts was recently constructed out of chains of Kronecker-Eis
enstein series. In this work\, we decompose a variety of more general genu
s-one integrands into the conjectural chain basis. The explicit form of th

DESCRIPTION:Speakers: Peng Zhao (Institute of Theoretical Physics\, Chines
e Academy of Sciences)\nWe introduce worldsheet variables for a certain mo
duli space associated with a Dynkin diagram of finite type. The constructi
on is based on gluing a pair of A-type quivers. We find new nonlinear fact
ors that characterize such spaces as hypersurface arrangement complement.
We study various topological properties using a finite-field method and pr
opose conjectures about quasi-polynomial point count\, dimensions of cohom
ology\, and Euler characteristics for the Dn space up to n=10. These new v
ariables have applications for string integrals\, cluster alphabets\, etc.

DESCRIPTION:Speakers: Ken Matsuno (Osaka City University)\nWe study the Ha
wking radiation from the five-dimensional charged static squashed Kaluza-K
lein black hole by the tunneling of charged fermions and charged scalar pa
rticles\, including the phenomenological quantum gravity effects predicted
by the generalized uncertainty principle with the minimal measurable leng
th. We derive corrections of the Hawking temperature to general relativity
\, which are related to the energy of the emitted particle\, the size of t
he compact extra dimension\, the charge of the black hole and the existenc
e of the minimal length in the squashed Kaluza-Klein geometry. We show tha
t the quantum gravity effect may slow down the increase of the Hawking tem
perature due to the radiation\, which may lead to the thermodynamic stable
remnant of the order of the Planck mass after the evaporation of the squa
shed Kaluza-Klein black hole. We also find that the sparsity of the Hawkin
g radiation may become infinite when the mass of the squashed Kaluza-Klein
black hole approaches its remnant mass.\n\nhttps://indico.nitep.osaka-cu.

DESCRIPTION:Speakers: Yoshinori Matsuo (Kyoto U)\nRecently\, it is propos
ed that the Hawking radiation contains the information of a region inside
the horizon called islands. In the calculation of the entanglement entropy
of the Hawking radiation\, the dominant contribution comes from the confi
guration with wormholes between replica geometries. Thus\, the entanglemen
t entropy of the Hawking radiation effectively includes the contribution f
rom the island. In this talk\, I will discuss the entanglement entropy in
the Schwarzschild spacetime\, and its relation to the vacuum state of matt
er fields.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/80/contributions/8

DESCRIPTION:Speakers: Sotaro Sugishita (Nagoya U)\nI will introduce the no
tion of target space entanglement. Quantum entanglement is closely related
to the structure of spacetime in quantum gravity. For quantum field theor
ies or statistical models\, we usually consider the base space entanglemen
t. However\, target space instead of base space sometimes directly connect
s to our spacetime\, for example\, perturbative string theories. We thus n
eed target space entanglement. To define the target space entanglement\, w
e have to generalize the definition of the conventional entanglement entro
py. I will explain this generalization and apply it to the first quantized
particles\, in particular\, fermions.\n\nhttps://indico.nitep.osaka-cu.ac

DESCRIPTION:Speakers: Katsuta Sakai (KEK)\nEntanglement entropy (EE) in fi
eld theory has been discussed as a measure for quantum entanglement betwee
n spatially separated regions. While there are a lot of studies on EE in C
FT and free theories\, EE in general interacting field theories is of inte
rest in an attempt to associate the effect of the entanglement with low-en
ergy physics. In this talk\, I introduce our study on EE in interacting fi
eld theories with a subregion of a half space. There\, some contributions
to EE can be expressed in terms of renormalized correlators of fundamental
and composite operators. Moreover\, by combining the result with the noti
on of the Wilsonian RG\, we discuss the possibility that EE relevant to lo
w-energy effective theories consists only of those contributions.\nThis ta
lk is based on 2103.05303\, 2105.02598\, 2105.14834 and our recent work in
progress.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/80/contributions/8

DESCRIPTION:Speakers: Rinto Kuramochi (SOKENDAI/KEK)\nIn F-theory\, if a f
iber type of an elliptic fibration involves a condition that requires an e
xceptional curve to split into two irreducible components\, it is called
“split” or “non-split” type depending on whether it is globally po
ssible or not. In the latter case\, the gauge symmetry is reduced to a non
-simply-laced Lie algebra due to monodromy. We show that the transition fr
om a split to a non-split model is\, except in certain exceptional cases\,
a conifold transition from the resolved to the deformed side\, associated
with the conifold singularities emerging at the codimension-two loci wher
e the codimension-one singularity is enhanced to $D_{2k+2} (k \\geq 1)$ or
$E_7$. This clarifies the origin of non-local matter in the non-split cas
e\, which has been a mystery for many years.\nReference: arXiv:2108.10136

DESCRIPTION:Speakers: Junichi Sakamoto ()\nRecently\, a unified picture to
describe integrable systems has been established by Costello\, Witten and
Yamazaki. In the case of 2D integrable field theories\, Costello and Yama
zaki proposed that by starting from a certain 4D Chern-Simons (CS) theory\
, one can construct classically integrable field theories systematically b
y taking a meromorphic 1-form and adopting an appropriate boundary conditi
on. In this talk\, I will explain how the AdS5×S5 supercoset sigma model
and its integrable deformations can be reproduced from a 4D CS theory by g
eneralizing the procedure for the 2D principal chiral model developed by D
elduc et al [arXiv:1909.13824].\nThis talk is based on works (2003.07309\,

DESCRIPTION:Speakers: Yoshihisa Kitazawa (KEK)\nWe investigate infrared lo
garithms in inflationary Universe from holographic perspective. We derive
gravitational Fokker-Planck and Langevin equations to investigate the time
evolution of the de Sitter entropy $S=\\pi/G_N H^2(t)$. $H(t)$ is the tim
e dependent effective Hubble parameter and $G_N$ is the Newton's constant.
Our approach focuses on the conformal modes to respect local Lorentz symm
etry. In term of the curvature perturbations \, it is shown to be consiste
nt with $\\delta N$ formalism. Under the Gaussian approximation\, we obtai
n the dynamical $\\beta$ function of $g=1/S$. The dimensionless gravitatio
nal coupling $g$ is asymptotically free toward the future. It also possess
es the ultraviolet fixed point indicating that the Universe begun with the
de Sitter expansion at the Planck scale with $\\epsilon=0$. We further in
terpret inflationary Universes as the UV complete composite states. Since
our analysis is trustable for small $g$\, our conclusion is that inflatio
nary universe is consistent in the semiclassical regime.\n\nhttps://indico
