Query: 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.
