摘要：

Using molecular dynamics simulations we investigate the dynamic structure factor S(k, omega) of a two-component model plasma where the Coulomb interaction is regularized at short distances. New simulation results are presented and discussed, and they are used to verify different theoretical treatments: the standard random-phase approximation, a dynamic local field correction with input from a new approach, which includes a dynamic collision frequency via the Mermin ansatz.
