Electromagnetic Radiation in a Semi-Compact Space
Satoshi Iso, Noriaki Kitazawa, Sumito Yokoo
In this note, we investigate the electromagnetic radiation emitted from a revolving point charge in a compact space. If the point charge is circulating with an angular frequency $ω…
Enhancements in F-theory models on moduli spaces of K3 surfaces with rank 17
Yusuke Kimura, Shun'ya Mizoguchi
We study the moduli of elliptic K3 surfaces with a section with the rank 17. While the Picard number of a generic K3 surface in such moduli space is 19, the Picard number is…
Secular Terms in Dyson Series to All-Orders of Perturbation
Satoshi Iso, Hikaru Ohta, Takao Suyama
In classical and quantum systems, perturbation of an evolution equation is often invalidated by secular terms which diverge at late times. The diverging behavior of evolution can b…
Quantum gravity fluctuations flatten the Planck-scale Higgs potential
Astrid Eichhorn, Yuta Hamada, Johannes Lumma +1
We investigate asymptotic safety of a toy model of a singlet-scalar extension of the Higgs sector including two real scalar fields under the impact of quantum-gravity fluctuations.…
Sequestering Mechanism in Scalar-Tensor Gravity
Takuma Tsukamoto, Taishi Katsuragawa, Shin'ichi Nojiri
We make a theoretical prediction for the ratio of the dark energy to other components in the Universe based on the scenario of the sequestering mechanism which was recently propose…
Structure of stable degeneration of K3 surfaces into pairs of rational elliptic surfaces
Yusuke Kimura
F-theory/heterotic duality is formulated in the stable degeneration limit of a K3 fibration on the F-theory side. In this note, we analyze the structure of the stable degeneration…
Double-winding Wilson loop in Yang-Mills theory: A criterion for testing the confinement models
Ryutaro Matsudo, Kei-Ichi Kondo, Akihiro Shibata
We examine how the average of double-winding Wilson loops depends on the number of color in the Yang-Mills theory. In the case where the two loops and are i…
Electromagnetic Duality and the Electric Memory Effect
Yuta Hamada, Min-Seok Seo, Gary Shiu
We study large gauge transformations for soft photons in quantum electrodynamics which, together with the helicity operator, form an ISO(2) algebra. We show that the two non-compac…
M2- and M5-branes in E11 Current Algebra Formulation of M-theory
Shotaro Shiba, Hirotaka Sugawara
Equations of motion for M2- and M5-branes are written down in the current algebra formulation of M-theory. These branes correspond to currents of the second and the fifth…
Soft pion theorem, asymptotic symmetry and new memory effect
Yuta Hamada, Sotaro Sugishita
It is known that soft photon and graviton theorems can be regarded as the Ward-Takahashi identities of asymptotic symmetries. In this paper, we consider soft theorem for pions, i.e…

Ryuichiro Kitano, Takao Suyama, Norikazu Yamada
In gauge theory, it is argued recently that there exists a "mixed anomaly" between the CP symmetry and the 1-form symmetry at , and the anomaly matching…
Vacuum fluctuations in an ancestor vacuum: A possible dark energy candidate
Hajime Aoki, Satoshi Iso, Da-Shin Lee +2
We consider an open universe created by bubble nucleation, and study possible effects of an "ancestor vacuum" (de Sitter space in which bubble nucleation occurred) on the present u…
Full diffeomorphism and Lorentz invariance in 4D superfield description of 6D SUGRA
Hiroyuki Abe, Shuntaro Aoki, Yutaka Sakamura
We complete the four-dimensional superfield description of six-dimensional supergravity. The missing ingredients in the previous works are the superfields that contain…
Regular Multi-Horizon Black Holes in Modified Gravity with Non-Linear Electrodynamics
Shin'ichi Nojiri, S. D. Odintsov
We investigated the regular multi-horizon black holes in the Einstein gravity, gravity and the 5 dimensional Gauss-Bonnet gravity, all of them coupled with non-linear electr…
Weak Gravity Conjecture, Multiple Point Principle and the Standard Model Landscape
Yuta Hamada, Gary Shiu
The requirement for an ultraviolet completable theory to be well-behaved upon compactification has been suggested as a guiding principle for distinguishing the landscape from the s…
Strong Coupling Limit of A Family of Chern-Simons-matter Theories
Takao Suyama
We investigate the strong coupling limit of a family of Chern-Simons-matter theories in the planar limit. The family consists of theories with the gauge group ${\rm U}…
A new method for probing the late-time dynamics in the Lorentzian type IIB matrix model
Takehiro Azuma, Yuta Ito, Jun Nishimura +1
The type IIB matrix model has been investigated as a possible nonperturbative formulation of superstring theory. In particular, it was found by Monte Carlo simulation of the Lorent…
Entanglement-induced quantum radiation
Satoshi Iso, Rumi Tatsukawa, Kazushige Ueda +1
Quantum entanglement of the Minkowski vacuum state between left and right Rindler wedges generates thermal behavior in the right Rindler wedge, which is known as the Unruh effect.…
Non-Gaussian and loop effects of inflationary correlation functions in BRST formalism
Hiroyuki Kitamoto, Yoshihisa Kitazawa, Ryota Kojima
We investigate inflationary correlation functions in single field inflation models. We adopt a BRST formalism where locality and covariance at the sub-horizon scale are manifest. T…
Large gauge transformation and little group for soft photons
Yuta Hamada, Min-Seok Seo, Gary Shiu
Recently, large gauge transformation (LGT), the residual gauge symmetry after gauge fixing that survives at null infinity, has drawn much attention concerning soft theorems and the…
Physical Cosmological Constant in Asymptotically Background Free Quantum Gravity
Ken-ji Hamada, Mikoto Matsuda
We study the effective potential in renormalizable quantum gravity with a single dimensionless conformal coupling without a Landau pole. In order to describe a background-free dyna…
Microstates of black holes in expanding universe from interacting branes
Shotaro Shiba
Thermodynamics of the near extremal black p-branes can be described by collective motions of gravitationally interacting branes. This proposal is called the p-soup model. In this p…
Axial gravity, massless fermions and trace anomalies
L. Bonora, M. Cvitan, P. Dominis Prester +3
This article deals with two main topics. One is odd parity trace anomalies in Weyl fermion theories in a 4d curved background, the second is the introduction of axial gravity. The…
Asymptotic safety of higher derivative quantum gravity non-minimally coupled with a matter system
Yuta Hamada, Masatoshi Yamada
We study asymptotic safety of models of the higher derivative quantum gravity with and without matter. The beta functions are derived by utilizing the functional renormalization gr…
