superconductivity and spintronics. Although the Dirac points are not necessarily associated …

Chiral separation effect catalyzed by heavy impurities

D Suenaga, Y Araki, K Suzuki, S Yasui - Physical Review D, 2021 - APS
We investigate the influence of the Kondo effect, namely, the nonperturbative effect induced
by heavy impurities, on the chiral separation effect (CSE) in quark matter. We employ a …

Key observable for linear thermalization

Y Chiba, A Shimizu - Physical Review Research, 2023 - APS
For studies on thermalization of an isolated quantum many-body system, the fundamental
issue is to determine whether a given system thermalizes or not. However, most studies …

Anisotropic magnetic response of Weyl semimetals in a topological insulator multilayer

T Aftab, K Sabeeh - Journal of Applied Physics, 2020 - pubs.aip.org
Magnetic susceptibility of Weyl semimetals, placed in a tilted magnetic field, is studied. Weyl
semimetals have three contributions: spin, orbital, and spin–orbital; all three contributions …

Long-range spin transport on the surface of topological Dirac semimetal

Y Araki, T Misawa, K Nomura - Physical Review Research, 2021 - APS
We theoretically propose the long-range spin transport mediated by the gapless surface
