The Spectrum of Electronic Vibrations in a Degenerate
Nonrelativistic Plasma
Soviet Physics JETP, Vol. 73, No. 5(11), Pp. 821-826 (1991)
Abstract
We study the spectrum of electronic vibrations in an ideal degenerate
cold nonrelativistic plasma. We obtain an expression for Landau damping,
which is nonzero in the zero-sound range even at T=0. Under the conditions
considered the electronic vibrations spectrum has been found to have a
terminal point. Expressions for all characteristic wave vectors are
also derived, namely for the one from which Landau damping begins as its
value increases, for the second at which the maximum frequency is
attained, and for the third corresponding to the terminal point.
All these values are found to be of the same order of magnitude and
differ only in logarithmic factors.
