Abstract

The plasma screening model, taking into account the electronic exchange-correlation effects and the ionic non-ideality in dense quantum plasmas, is presented. This model can be used as an input in various plasma interaction models to calculate the scattering cross-sections and transport properties. The application of the presented plasma screening model is demonstrated on the example of the temperature relaxation rate in dense hydrogen and warm dense aluminum. Additionally, we compute the conductivity of warm-dense aluminum in the regime where collisions are dominated by electron-ion scattering. The obtained results are compared with available theoretical results and simulation data.
