Using recently obtained ac conductivity data we have derived dc conductivity together with free electron density and electron momentum relaxation time in two-temperature warm dense gold with energy density up to 4.1 MJ/kg ( 0.8 × 1011 J / m3 ). The derivation is based on a Drude interpretation of the dielectric function that takes into account contributions of intraband and interband transitions as well as atomic polarizability. Overall, the results provide valuable benchmarks for assessing the extended Ziman formula for electrical resistivity and an accompanying average atom model.
