Classification of Modular Symmetries in Type IIB Flux Landscape
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +2
In this work, we study modular symmetries in type IIB flux landscape by investigating symplectic basis transformations of period vectors on toroidal orbifolds. To fix explicit cycl…
Evidence of a CP broken deconfined phase in 4D SU(2) Yang-Mills theory at from imaginary simulations
Mitsuaki Hirasawa, Masazumi Honda, Akira Matsumoto +2
The spontaneous breaking of CP symmetry in 4D SU() pure Yang-Mills theory at has recently attracted much attention in the context of the higher-form symmetry and the 't Ho…
Monopole Breaking of Chern-Weil Symmetries
Eduardo García-Valdecasas, Matthew Reece, Motoo Suzuki
Gauge theories in dimensions with a nontrivial fundamental group admit a -form magnetic symmetry and a -form instantonic symmetry. These are examples of Chern-Wei…
Stabilization of a twisted modulus on a mirror of rigid Calabi-Yau manifold
Keiya Ishiguro, Takafumi Kai, Hajime Otsuka
We study the stabilization of a twisted modulus in Type IIB flux compactifications on a mirror of the rigid Calabi-Yau threefold. By analyzing the effective action of twisted and u…
Note on Warped Compactification -- Finite Brane Potentials and Non-Hermiticity --
Sudhakantha Girmohanta, Yuichiro Nakai, Motoo Suzuki +2
We study radius stabilization in the Randall-Sundrum model without assuming any unnaturally large stabilizing scalar potential parameter at the boundary branes () by the frequen…
A new infinite class of , supergravities
Gregory J. Loges
We present a new infinite class of non-abelian, 6d supergravities with eight supercharges. These theories not only satisfy all known low-energy consistency conditions, such as bein…
Pauli-Villars regularization of Kaluza-Klein Casimir energy with Lorentz symmetry
Hiroki Matsui, Yutaka Sakamura
The Pauli-Villars regularization is appropriate to discuss the UV sensitivity of low-energy observables because it mimics how the contributions of new particles at high energies ca…
Quantum Gravity Effective Action Provides Entropy of The Universe
Ken-ji Hamada
The effective action in renormalizable quantum theory of gravity provides entropy because the total Hamiltonian vanishes. Since it is a renormalization group invariant that is cons…
Towards a complete classification of 6D supergravities
Yuta Hamada, Gregory J. Loges
The constraints arising from anomaly cancellation are particular strong for chiral theories in six dimensions. We make progress towards a complete classification of 6D supergraviti…
Circularly polarized gravitational waves in Chern-Simons gravity originated from an axion domain wall
Sugumi Kanno, Jiro Soda, Akira Taniguchi
We study a scattering problem of gravitational waves (GWs) by an axion domain wall in Chern-Simons (CS) gravity. We find that circular polarization of GWs is produced after passing…
Novel transition dynamics of topological solitons
Kentaro Nishimura, Noriyuki Sogabe
Continuous phase transitions can be classified into ones characterized by local-order parameters and others that need additional topological constraints. The critical dynamics near…
Stringy Threshold Corrections in D-brane Systems
Satoshi Iso, Noriaki Kitazawa, Takao Suyama
We investigate string amplitudes by using the partial modular transformation which we introduced in our previous works. This enables us to extract stringy threshold corrections fro…
A 10d construction of Euclidean axion wormholes in flat and AdS space
Gregory J. Loges, Gary Shiu, Thomas Van Riet
Euclidean wormhole geometries sourced by axions and dilatons are puzzling objects in quantum gravity. From one side of the wormhole to the other, the scalar fields traverse a few P…
A peak in the power spectrum of primordial gravitational waves induced by primordial dark magnetic fields
Sugumi Kanno, Ann Mukuno, Jiro Soda +1
Dark gauge fields have been discussed as candidates for dark matter recently. If they existed, primordial dark magnetic fields during inflation would have existed. It is believed t…
On (Scalar QED) Gravitational Positivity Bounds
Yuta Hamada, Rinto Kuramochi, Gregory J. Loges +1
We study positivity bounds in the presence of gravity. We first review the gravitational positivity bound at the tree-level, where it is known that a certain amount of negativity i…
Full higher-dimensional analysis of moduli oscillation and radiation in expanding universe
Hajime Otsuka, Yutaka Sakamura
We investigate effects of the radiation and the moduli oscillation around the stabilized values on the evolution of a 6-dimensional spacetime compactified on . In order to see…
BCF anomaly and higher-group structure in the low energy effective theories of mesons
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We discuss the BCF anomaly of massless QCD-like theories, first obtained by Anber and Poppitz, from the viewpoint of the low energy effective theories. We assume that the QCD-like…
Gauged Double Field Theory, Current Algebras and Heterotic Sigma Models
Machiko Hatsuda, Haruka Mori, Shin Sasaki +1
We study the generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the $O(D,D+n)…
Higher-group structure in -dimensional axion-electrodynamics
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We investigate -dimensional axion electrodynamics for the purpose of exploring a higher-group structure underlying it. This is manifested as a Green-Schwarz transformation of t…
Progress in the numerical studies of the type IIB matrix model
Konstantinos N. Anagnostopoulos, Takehiro Azuma, Kohta Hatakeyama +5
The type IIB matrix model, also known as the IKKT model, has been proposed as a promising candidate for a non-perturbative formulation of superstring theory. Based on this proposal…
Partial deconfinement: a brief overview
Masanori Hanada, Hiromasa Watanabe
The confinement/deconfinement transition in gauge theory plays important roles in physics, including the description of thermal phase transitions in the dual gravitational theory.…
Superluminal propagation from IR physics
Asuka Ito, Teruaki Suyama
One may believe that front velocities of waves in a given theory coincide with the UV limit of phase velocities for any dispersion relations. This implies that IR physics is irrele…
Baby universes in 2d and 4d theories of quantum gravity
Yuta Hamada, Hikaru Kawai, Kiyoharu Kawana
The validity of the Coleman mechanism, which automatically tunes the fundamental constants, is examined in two-dimensional and four-dimensional quantum gravity theories. First, we…
Hybrid metric-Palatini Higgs inflation
Minxi He, Yusuke Mikura, Yuichiro Tada
We propose an extension of the Higgs inflation to the hybrid metric-Palatini gravity, where we introduce non-minimal couplings between Higgs and both the metric-type and the Palati…
