Abstract

For the case of finite lifetime broadening the standard Kubo formula for the optical conductivity tensor is rederived in terms of Green's functions by using contour integrations, whereby finite temperatures are accounted for by using the Fermi-Dirac distribution function. For zero lifetime broadening, the present formalism is related to expressions well known in the literature. Numerical aspects of how to calculate the corresponding contour integrals are also outlined.
