Decay of Langmuir wave in dense plasmas and warm dense matter

摘要

The decays of the Langmuir waves in dense plasmas are computed using thedielectric function theory widely used in the solid state physics. Four cases are considered: a classical plasma, a Maxwellian plasma, adegenerate quantum plasma, and a partially degenerate plasma. The result isconsiderably different from the conventional Landau damping theory.
