An advanced method for computing the intrinsic spin Hall conductivity from first principles — •Minsu Ghim, Ji Hoon Ryoo, and Cheol-Hwan Park — Department of Physics and Astronomy, Seoul National University, Seoul 08826, Korea, Center for Correlated Electron Systems, Institute for Basic Science, Seoul 08826, Korea, Center for Theoretical Physics, Seoul National University, Seoul 08826, Korea

Spin Hall effect plays a key role in spintronics. It is widely accepted that the spin Hall conductivity can be categorized into three different contributions: skew-scattering, side-jump, and intrinsic. Recently, methods for computing the intrinsic spin Hall conductivity from first principles using the maximally-localized Wannier functions have been reported [1,2]. In this talk, we present technical improvements of the original method [2] in terms of computational efficiency.
