The Influence of Dynamical Screening on the Transport Properties of Dense Plasmas

摘要

We investigate the effects of dynamical screening on the static transport properties. We review the low density expansion for the electron-electron and electron-ion correlation functions and give results for a 6-moment approach within linear response theory. The expansion coefficients are given. The convergence of thermoelectric transport coefficients is examined in dependence of the rank of the collision term determinant. The results are compared with previous calculations and experiments. Effective Debye screening radii derived from the Gould-DeWitt scheme for the inclusion of strong collisions as well as dynamical effects are discussed.
