Theory of spin Seebeck effect activated by acoustic chiral phonons
Naoki Nishimura, Takumi Funato, Mamoru Matsuo +1
We theoretically explore the generation of spin current driven by a temperature gradient in a junction between a chiral insulator and a normal metal. Based on the gyromagnetic resp…

Spin current generation due to differential rotation
Takumi Funato, Shunichiro Kinoshita, Norihiro Tanahashi +2
We study nonequilibrium spin dynamics in differentially rotating systems, deriving an effective Hamiltonian for conduction electrons in the comoving frame. In contrast to conventio…

Curvature-induced valley-dependent spin-orbit interaction
A. Yamakage, T. Sato, R. Okuyama +5
We construct a general theoretical framework for describing curvature-induced spin-orbit interactions on the basis of group theory. Our theory can systematically determine the emer…
