The dynamic conductivity of strongly non-ideal plasmas: is the Drude model valid?

The method of moments is used to calculate the dynamic conductivity of strongly coupled fully ionized hydrogen plasmas. The electron density $n_e$ and temperature $T$ vary in the domains $ 10^{21} < n_{e} < 10^{24} {\rm cm}^{-3}$,$10^{4} {\rm K} < T < 10^{6} {\rm K}$. The results are compared to some theoretical data.
