Karpman-Washimi magnetization in relativistic quantum plasmas

Abstract

An interesting phenomenon of ponderomotive Karpman-Washimi magnetization is investigated in ultrarelativistic degenerate plasmas. The quantum characteristics of plasma electrons are considered on incorporating the Fermi pressure and exchange-correlation potential terms into the fluid model of plasmas. The ion fluid is referred to as classically warm. The Karpman-Washimi ponderomotive magnetization M-K-W(Str) and radiation power P-K-W(Str) are derived as functions of scaled wave number (k) over bar, scaled effective frequency (omega) over bar (*), ratio of thermal temperature of ions to the Fermi temperature of electrons (E) over bar (1)(P) , and fine structure constant alpha for two cases of streaming and nonstreaming quantum plasmas. It has been observed that the Karpman-Washimi ponderomotive magnetization M-K-W(Str) and the Karpman-Washimi radiation power P-K-W(Str) are significantly affected by the scaled streaming velocity (upsilon) over bar (0)
