Issues in the calculations of dc conductivity of warm dense aluminium

Abstract

Abstract In the Ziman‐Evans formulation, the electrical resistivity involves several quantities like the plasma mean ionization and chemical potential, the electron‐ion scattering cross‐section, the ion‐ion structure factor, and the derivative of the Fermi distribution with respect to electron energy. Therefore, to make significant progress while comparing different models or analysing experimental measurements, it is important to try to get insight into such partial physical quantities. In the present work, we propose to investigate the sensitivity of the resistivity to the different physical quantities required for its computation.
