Second-order dc conductivity in the velocity-gauge Keldysh formalism: gauge-invariant decomposition into nonlinear Drude, Berry-curvature-dipole, and quantum-metric responses
Junya Shibata
We derive a gauge-invariant clean-limit decomposition of the second-order dc nonlinear conductivity in multiband tight-binding systems within the velocity-gauge Keldysh Green's fun…
Theory of electromagnetic wave propagation in ferromagnetic Rashba conductor
Junya Shibata, Akihito Takeuchi, Hiroshi Kohno +1
We present a comprehensive study of various electromagnetic wave propagation phenomena in a ferromagnetic bulk Rashba conductor from the perspective of quantum mechanical transport…
Theory of anomalous optical properties of bulk Rashba conductor
Junya Shibata, Akihito Takeuchi, Hiroshi Kohno +1
The Rashba interaction induced when inversion symmetry is broken in solids is a key interaction connecting spin and charge for realizing novel magnetoelectric cross-correlation eff…
Spin torque due to diffusive spin current in magnetic texture
Kazuhiro Hosono, Junya Shibata, Hiroshi Kohno +1
We present a microscopic theory of spin torque due to diffusive spin currents induced by spin accumulation. The obtained expression is a natural extension of the existing one due t…
Spin and charge transport induced by gauge fields in a ferromagnet
Junya Shibata, Hiroshi Kohno
We present a microscopic theory of spin-dependent motive force ("spin motive force") induced by magnetization dynamics in a conducting ferromagnet, by taking account of spin relaxa…
Microscopic Theory of Current-Spin Interaction in Ferromagnets
H. Kohno, S. Kawabata, T. Noguchi +3
Interplay between magnetization dynamics and electric current in a conducting ferromagnet is theoretically studied based on a microscopic model calculation. First, the effects of t…
