Electric Ferro-Axial Moment as Nanometric Rotator and Source of Longitudinal Spin Current
Satoru Hayami, Rikuto Oiwa, Hiroaki Kusunose
An electric ferro-axial moment, which is characterized by a nonzero expectation value of a time-reversal-even axial vector, exhibits distinct spatial-inversion and time-reversal pr…
Analysis of model parameter dependences on the second-order nonlinear conductivity in -symmetric collinear antiferromagnetic metals with magnetic toroidal moment on zigzag chains
Megumi Yatsushiro, Rikuto Oiwa, Hiroaki Kusunose +1
A magnetic toroidal moment is a fundamental electronic degree of freedom in the absence of both spatial inversion and time-reversal symmetries and gives rise to novel multiferroic…
Systematic analysis method for nonlinear response tensors
Rikuto Oiwa, Hiroaki Kusunose
We propose a systematic analysis method for identifying essential parameters in various linear and nonlinear response tensors without which they vanish. By using the Keldysh formal…
