Spin-orbit interactions and spin-currents from an exact-exchange Kohn-Sham method

TL;DR

This paper introduces an exact-exchange spin-current Kohn-Sham method that self-consistently models non-collinear spins, magnetic effects, and spin-orbit interactions, demonstrating how spin-orbit coupling induces spin-currents in materials like silicon and germanium.

Contribution

The paper presents a novel self-consistent method to accurately model spin-currents and spin-orbit effects within the Kohn-Sham framework.

Findings

Spin-orbit interactions induce spin-currents in materials.

Results demonstrate the method's effectiveness on silicon and germanium.

The approach captures magnetic effects and non-collinear spins accurately.

Abstract

An exact-exchange spin-current Kohn-Sham method to treat non-collinear spin, magnetic effects, currents, spin-currents, and spin-orbit interactions self-consistently on equal footing is introduced. Spin-orbit interactions are shown to induce spin-currents. Results for silicon and germanium are presented.
