Wannier interpolation of spin accumulation coefficient
Abstract The spin Hall (SH) effect is widely understood as a phenomenon in which spin current flows perpendicular to an electric field. In the presence of a spin-orbit coupling, however, spin current is ambiguous, and the SH conductivity depends on the definition of spin current. In this article, we...

| description | Abstract The spin Hall (SH) effect is widely understood as a phenomenon in which spin current flows perpendicular to an electric field. In the presence of a spin-orbit coupling, however, spin current is ambiguous, and the SH conductivity depends on the definition of spin current. In this article, we develop an ab initio computational scheme for the spin accumulation coefficient, which characterizes the spin accumulation and would be an alternative indicator of the SH effect. The proposed method has been implemented into an open-source software Wannier90 and serves high-precision ab initio research on the SH effect. |
