Comparison of various damping rates of a plasma of , a reproduction of Fig. 1 in Ref. 7, which is included for the purpose of self-containment. The prediction from the classical dielectric function (solid line) for is compared with that of the DuBois’ theory (dashed line) for . The experimental measurements for AL are adapted from Fig. 3 in Ref. 21, which are originally from Ref. 27 (crosses), Ref. 28 (circles), and Ref. 29 (triangles).
The decay rates in a classical 400 eV hydrogen plasma (dot-dashed line), a degenerate plasma (solid line), and a partially degenerate plasma (dashed line), where . Note that the decay rate from the Landau damping theory is not included throughout the rest of the figures, as it is negligibly small. The electron temperature of the partially degenerate plasma is .
The damping rate of a 36 eV hydrogen plasma when .
The damping rates of degenerate hydrogen plasmas for two cases of electron density.
Stability conditions given in Eqs. (38) and (39) for hydrogen plasmas. Only the degenerate case is considered, but the same logic could apply to warm dense plasmas and hot dense plasmas.
