Calculation of the electrical conductivity of strongly coupled plasmas

The relativistic self-consistent average-atom model is employed to calculate the electrical conductivity of strongly coupled plasmas by using the extended Ziman formula. Calculation results for Fe plasma are compared with several theoretical models. For strongly correlated liquid metals, the electrical resistivities appear to be closer to the experimental data than that in G. A. Rinker, Phys. Rev. A 37, 1284 (1988), since fully self-consistent potentials based upon solutions of the Dirac equation are used. The numerical results for Al plasma are largely consistent with the available experimental values [H. M. Milchberg et al., Phys. Rev. Lett. 61, 2364 (1988)]. Additional calculations show that contributions from the electron-ion inelastic scattering are negligible. Some results for Au plasma are also given for application.
