Axion instability and non-linear electromagnetic effect
Tatsushi Imaeda, Yuki Kawaguchi, Yukio Tanaka +1
We investigate the instability due to dynamical axion field near the topological phase transition of insulators. We first point out that the amplitude of dynamical axion field is b…
Electromagnetic effects induced by time-dependent axion field
Katsuhisa Taguchi, Tatsushi Imaeda, Tetsuya Hajiri +4
We studied the dynamics of the so-called -term, which exists in topological materials and is related to a hypothetical field predicted by Peccei-Quinn in particle physics, in a…
Photovoltaic Chiral Magnetic Effect
Katsuhisa Taguchi, Tatsushi Imaeda, Masatoshi Sato +1
We theoretically predict a generation of a current in Weyl semimetals by applying circularly polarized light. The electric field of the light can drive an effective magnetic field…
