Field theoretical approach to spin torques: Slonczewski torques
Junji Fujimoto
The quantum field theoretical approach with the Kubo formula has successfully captured spin torques, such as spin-transfer torques and spin-orbit torques, for continuum systems. We…

Spin Hall effect driven by the spin magnetic moment current in Dirac materials
Zhendong Chi, Guanxiong Qu, Yong-Chang Lau +5
The spin Hall effect of a Dirac Hamiltonian system is studied using semiclassical analyses and the Kubo formula. In this system, the spin Hall conductivity is dependent on the defi…

Chirality-dependent second-order spin current in systems with time-reversal symmetry
Ryosuke Hirakida, Junji Fujimoto, Masao Ogata
Spin currents proportional to the first- and second-order of the electric field are calculated in a specific tight-binding model with time-reversal symmetry. Specifically, a tight-…
