On post-inflation validity of perturbation theory in Horndeski scalar-tensor models
Cristiano Germani, Nina Kudryashova, Yuki Watanabe
By using the newtonian gauge, we re-confirm that, as in the minimal case, the re-scaled Mukhanov-Sasaki variable is conserved leading to a constraint equation for the Newtonian pot…
Study of entropy production in Yang-Mills theory with use of Husimi function
Hidekazu Tsukiji, Hideaki Iida, Teiji Kunihiro +2
Understanding the thermalization process in a pure quantum system is a challenge in theoretical physics. In this work, we explore possible thermalization mechanism in Yang-Mills(YM…
The warping matrix of a knot diagram
Ayaka Shimizu
We introduce the warping matrix which is a new description of oriented knots from a viewpoint of warping degree.
A look inside charmed-strange baryons from lattice QCD
K. U. Can, G. Erkol, M. Oka +1
The electromagnetic form factors of the spin-3/2 baryons, namely , , and , are calculated in full QCD on PACS-CS lattices wi…
Evolution of the density of states at the Fermi level across the metal-to-insulator crossover in alkali doped zeolite
Mutsuo Igarashi, Peter Jeglic, Andraz Krajnc +4
We report a systematic nuclear magnetic resonance investigation of the Na spin-lattice relaxation rate, , in sodium loaded low-silica X (LSX) zeolite, Na/Na$_{12}…
Entropy production in quantum Yang-Mills mechanics in semi-classical approximation
Hidekazu Tsukiji, Hideaki Iida, Teiji Kunihiro +2
We discuss thermalization of isolated quantum systems by using the Husimi-Wehrl entropy evaluated in the semiclassical treatment. The Husimi-Wehrl entropy is the Wehrl entropy obta…
Multi-disformal invariance of nonlinear primordial perturbations
Yuki Watanabe, Atsushi Naruko, Misao Sasaki
We study disformal transformations of the metric in the cosmological context. We first consider the disformal transformation generated by a scalar field and show that the curva…
Large tensor mode, field range bound and consistency in generalized G-inflation
Taro Kunimitsu, Teruaki Suyama, Yuki Watanabe +1
We systematically show that in potential driven generalized G-inflation models, quantum corrections coming from new physics at the strong coupling scale can be avoided, while produ…
A CA Hybrid of the Slow-to-Start and the Optimal Velocity Models and its Flow-Density Relation
Hideaki Ujino, Tetsu Yajima
The s2s-OVCA is a cellular automaton (CA) hybrid of the optimal velocity (OV) model and the slow-to-start (s2s) model, which is introduced in the framework of the ultradiscretizati…
Multi-field formulation of gravitational particle production after inflation
Yuki Watanabe, Jonathan White
We study multi-field inflation models that contain a non-trivial field-space metric and a non-minimal coupling between the gravity and inflaton sectors. In such models it is known…
