Dynamical conductivity of the dense semiclassical plasmas on the basis of the effective potential

Abstract

New results on the dynamical conductivity and dynamical collision frequency of dense semiclassical hydrogen plasmas on the basis of the effective interaction potential (taking into account screening and diffraction effects) are presented. The electron density ne and temperature T vary in the domains 1021 cm−3<ne<1024 cm−3 and 104 K<T<106 K, correspondingly. A semiclassical method has been used for the calculation of the collision frequency. Using a generalized Drude formula, the dynamical conductivity has been investigated. The influence of electron-electron interactions was taken into account at the level of collision frequency via a renormalization factor. The results of the dynamical conductivity show good agreement with the data of other authors, notably with the molecular-dynamics simulation, which also includes electron-electron interactions.
