An improved method for computing dynamical conductivity
ORAL
Abstract
Recently, methods for computing dynamical conductivity including anomalous Hall and spin Hall conductivity from first principles, have been developed. [1,2] The analytic tetrahedron interpolation method was suggested, and the Wannier interpolation scheme allowed computation with a dense grid. [3] With the aid of these, we present further technical improvements in the tetrahedron method for both the real part and the imaginary part of conductivity.
