A wide-range modeling approach for the thermal conductivity and dielectric function of solid and liquid aluminum

This study aims at providing a simple method to obtain the electronic thermal conductivity of aluminum over a wide range of temperatures and densities in the crystalline solid as well as the disordered liquid phase. All calculations are based on first order perturbation theory and the pseudo-potential theory without resorting to ab-initio simulations. Wherever possible, the results are compared to experimental data or quantum molecular dynamics simulations. In addition a straightforward approach is demonstrated to estimate the complex permittivity from the Drude model.
