  The Ziman formulation of electrical conductivity is tested in warm and hot
dense matter using the pseudo-atom molecular dynamics method. Several
implementation options that have been widely used in the literature are
systematically tested through a comparison to accurate but expensive Kohn-Sham
density functional theory molecular dynamics (KS-DFT-MD) calculations. The
comparison is made for several elements and mixtures and for a wide range of
temperatures and densities, and reveals a preferred method that generally gives
very good agreement with the KSDFT-MD results, but at a fraction of the
computational cost.
