More on a dessin on the base: Kodaira exceptional fibers and mutually (non-)local branes
Shin Fukuchi, Naoto Kan, Rinto Kuramochi +2
A "dessin d'enfant" is a graph embedded on a two-dimensional oriented surface named by Grothendieck. Recently we have developed a new way to keep track of non-localness among 7-bra…
T-dual Superstring Lagrangian with double zweibeins
Machiko Hatsuda, Warren Siegel
We present superstring Lagrangians with manifest T-duality. The Lagrangian version of the section conditions are necessary to make Lagrangians to be general coordinate invariant. W…
Emergent discrete 3-form symmetry and domain walls
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We show that axion models with the domain wall number in dimensions, i.e., periodic scalar field theories admitting axion domain walls, exhibit an emergent ${\mathb…
The emergence of expanding space-time and intersecting D-branes from classical solutions in the Lorentzian type IIB matrix model
Kohta Hatakeyama, Akira Matsumoto, Jun Nishimura +2
The type IIB matrix model is a promising candidate for a nonperturbative formulation of superstring theory. As such, it is expected to explain the origin of space--time and matter…
Calabi-Yau 4-folds and four-dimensional F-theory on Calabi-Yau 4-folds with U(1) factors
Yusuke Kimura
In this study, four-dimensional F-theory models with multiple U(1) gauge group factors are constructed. A class of rational elliptic 4-folds, which we call as "C…
Topics in gravity SCET: the diff Wilson lines and reparametrization invariance
Sabyasachi Chakraborty, Takemichi Okui, Arash Yunesi
Two topics in soft collinear effective theory (SCET) for gravitational interactions are explored. First, the collinear Wilson lines---necessary building blocks for maintaining mult…
F-theory Flux Vacua and Attractor Equations
Yoshinori Honma, Hajime Otsuka
We examine the vacuum structure of 4D effective theories of moduli fields in spacetime compactifications with quantized background fluxes. Imposing the no-scale structure for the v…
Calabi-Yau 3-folds, Calabi-Yau 3-folds as double covers, and F-theory with U(1)s
Yusuke Kimura
In this study, we introduce a new class of rational elliptic 3-folds, which we refer to as "1/2 Calabi-Yau 3-folds". We construct elliptically fibered Calabi-Yau 3-folds by utilizi…
Dynamics of Revolving D-Branes at Short Distances
Satoshi Iso, Noriaki Kitazawa, Hikaru Ohta +1
We study the behavior of the effective potential between revolving D-branes at all ranges of the distance , interpolating and ( is the string len…
Pole-skipping with finite-coupling corrections
Makoto Natsuume, Takashi Okamura
Recently, it is shown that many Green's functions are not unique at special points in complex momentum space using AdS/CFT. This phenomenon is similar to the pole-skipping in holog…
Unitary matrix with a Penner-like potential also yields N_f=2
Shun'ya Mizoguchi, Hajime Otsuka, Hitomi Tashiro
It has been known for some time that a hermitian matrix model with a Penner-like potential yields as its large-N free energy the prepotential of N=2 N_f=2 SU(2) SUSY gauge theory.…
From 3d dualities to hadron physics
Naoto Kan, Ryuichiro Kitano, Shimon Yankielowicz +1
When one of the space-time dimension is compactified on , the QCD exhibits the chiral phase transition at some critical radius. When we further turn on a background term w…
Flavor Moonshine
Shotaro Shiba Funai, Hirotaka Sugawara
The flavor moonshine hypothesis is formulated to suppose that all particle masses (leptons, quarks, Higgs and gauge particles -- more precisely, their mass ratios) are expressed as…
F-theory models with and transitions in discrete gauge groups
Yusuke Kimura
We examine the proposal in the previous paper to resolve the puzzle in transitions in discrete gauge groups. We focus on a four-section geometry to test the proposal. We observed t…
de Sitter duality and logarithmic decay of dark energy
Hiroyuki Kitamoto, Yoshihisa Kitazawa, Takahiko Matsubara
We investigate infrared dynamics of four-dimensional Einstein gravity in de Sitter space. We set up a general framework to investigate dynamical scaling relations in quantum/classi…
Duration of Classicality of an inhomogeneous quantum field with repulsive contact self-interactions
Ariel Arza, Sankha S. Chakrabarty, Seishi Enomoto +2
Quantum fields with large degeneracy are often approximated as classical fields. Here, we show how quantum and classical evolution of a highly degenerate quantum field with repulsi…
A note on transition in discrete gauge groups in F-theory
Yusuke Kimura
We observe a new puzzling physical phenomenon in F-theory on the multisection geometry, wherein a model without a gauge group transitions to another model with a discrete $\mathbb{…
Behaviors of two supersymmetry breaking scales in supergravity
Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1
We study the supersymmetry breaking patterns in four-dimensional gauged supergravity. The model contains multiple (Abelian) vector multiplets and a single hypermult…
Direct Calculation of Mutual Information of Distant Regions
Noburo Shiba
We consider the (Renyi) mutual information, , of distant compact spatial regions A and B in the vacuum state of a free sc…
Discrete gauge groups in certain F-theory models in six dimensions
Yusuke Kimura
We construct six-dimensional (6D) F-theory models in which discrete and gauge symmetries arise. We demonstrate that a spe…
Nonuniqueness of Green's functions at special points
Makoto Natsuume, Takashi Okamura
We investigate a new property of retarded Green's functions using AdS/CFT. The Green's functions are not unique at special points in complex momentum space. This arises because the…
Holographic chaos, pole-skipping, and regularity
Makoto Natsuume, Takashi Okamura
We investigate the "pole-skipping" phenomenon in holographic chaos. According to the pole-skipping, the energy-density Green's function is not unique at a special point in complex…
Linear Chern-Simons-matter Theories in the Planar Limit
Takao Suyama
We study linear Chern-Simons-matter theories in the planar limit. The matter content of the theory is depicted by a linear-shape diagram with nodes and links…
Complex Langevin analysis of the space-time structure in the Lorentzian type IIB matrix model
Jun Nishimura, Asato Tsuchiya
The Lorentzian type IIB matrix model has been studied as a promising candidate for a nonperturbative formulation of superstring theory. In particular, the emergence of (3+1)D expan…
