Relativistic Landau damping of longitudinal waves in isotropic pair plasmas

Laing, E.W. and Diver, D.A. (2006) Relativistic Landau damping of longitudinal waves in isotropic pair plasmas. Physics of Plasmas, 13(9), 092115. (doi: 10.1063/1.2353901)




Landau damping is described in relativistic electron-positron plasmas. Relativistic electron-positron plasma theory contains important new effects when compared with classical plasmas. For example, there are undamped superluminal wave modes arising from both a continuous and discrete mode structure, the former even in the classical limit. We present here a comprehensive analytical treatment of the general case resulting in a compact and useful form for the dispersion relation. The classical pair-plasma case is addressed, for completeness, in an appendix.
