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…
Nonreciprocal spin wave propagation in chiral-lattice ferromagnets
S. Seki, Y. Okamura, K. Kondou +8
Spin current, i.e. the flow of spin angular momentum or magnetic moment, has recently attracted much attention as the promising alternative for charge current with better energy ef…
Thermal vector potential theory of magnon-driven magnetization dynamics
Gen Tatara
Thermal vector potential formulation is applied to study thermal dynamics of magnetic structures in insulating ferromagnets. By separating variables of the magnetic structure and m…
Spin Dynamics with Inertia in Metallic Ferromagnets
Toru Kikuchi, Gen Tatara
Non-adiabatic contribution of environmental degrees of freedom yields effective inertia of spin in effective spin dynamics. In this paper, we study several aspects of the inertia o…
Thermal vector potential theory of transport induced by temperature gradient
Gen Tatara
A microscopic formalism to calculate thermal transport coefficients is presented based on a thermal vector potential, whose time-derivative is related to a thermal force. The forma…
