Plasmon dispersion of a weakly degenerate nonideal one-component plasma

Classical Molecular Dynamics simulations (MD) for a one-component weakly degenerate plasma are presented. Using an effective quantum pair potential (Kelbg potential), the dynamic structure factor and the dispersion of Langmuir waves are computed. The influence of the coupling strength $\Gamma$ and degree of degeneracy $\rho \Lambda^3$ on these properties is discussed. The results are compared with predictions of mean-field theories.
