Electrical resistivity of liquid expanded metals by Ziman approach

Transport properties of metals near the critical points were intensively studied. Using quantum dynamics simulations, we consider the structures of liquid aluminum and copper at high equilibrium temperatures and strong expansion. On the other hand, we carry out classical molecular dynamics simulations using the embedded atom method interatomic potentials. Both approaches provide data for resistivity calculations based on the well-known Ziman-Evans formula. The results of these calculations show a weak dependence on the used methods of ion structure computations. Also, we demonstrate that an effect of electron exchange and correlation is taken into account in electron-ion screening function, makes electric resistivity smaller in all considered situations.
