Nonreciprocal magnon excitations by the Dzyaloshinskii-Moriya interaction on the basis of bond magnetic toroidal multipoles
Takuya Matsumoto, Satoru Hayami
The microscopic conditions for the emergence of nonreciprocal magnon excitations in noncentrosymmetric magnets are theoretically investigated. We show that asymmetric magnon excita…
Classifying topological sector via machine learning
Masakiyo Kitazawa, Takuya Matsumoto, Yasuhiro Kohno
We employ a machine learning technique for an estimate of the topological charge of gauge configurations in SU(3) Yang-Mills theory in vacuum. As a first trial, we feed the fou…
Classifying Topological Charge in SU(3) Yang-Mills Theory with Machine Learning
Takuya Matsumoto, Masakiyo Kitazawa, Yasuhiro Kohno
We apply a machine learning technique for identifying the topological charge of quantum gauge configurations in four-dimensional SU(3) Yang-Mills theory. The topological charge den…
Kinetic theory for a simple modeling of phase transition: Dynamics out of local equilibrium
Shigeru Takata, Takuya Matsumoto, Anna Hirahara +1
This is a continuation of the previous work (Takata & Noguchi, J. Stat. Phys., 2018) that introduces the presumably simplest model of kinetic theory for phase transition. Here, mai…
Chiral Unitary Quantum Phase Transition in 2H-FeTaSe
Takuya Kanno, Takuya Matsumoto, Koichi Ichimura +2
We have observed a metal-insulator transition of a quasi-two dimensional electronic system in transition metal dichalcogenide -TaSe caused by doping iron. The sheet resista…
Yang-Baxter deformations of Minkowski spacetime
Takuya Matsumoto, Domenico Orlando, Susanne Reffert +2
We study Yang-Baxter deformations of 4D Minkowski spacetime. The Yang-Baxter sigma model description was originally developed for principal chiral models based on a modified classi…
