Effects of quantum statistical pressure on the Washimi-Karpman magnetization and power radiation in degenerate quantum Fermi-Dirac plasmas

Abstract

The physical properties of the Washimi-Karpman ponderomotive magnetization are investigated in relativistically degenerate quantum Fermi-Dirac plasmas including the influence of quantum statistical degeneracy pressure. The induced magnetization and power radiation due to the Washimi-Karpman ponderomotive interaction are obtained in Fermi-Dirac plasmas. It is found that the ponderomotive magnetization decreases with an increase of the relativistic degeneracy parameter. It is also shown that the quantum statistical degeneracy pressure effect is more significant in small frequency and large wave number domains than that in large frequency and small wave number domains. In addition, it is found that the ponderomotive power radiation decreases with an increase of the relativistic degeneracy parameter in Fermi-Dirac plasmas. The variations of the Washimi-Karpman magnetization and power radiation due to the physical characteristics of degenerate quantum Fermi-Dirac plasmas are also discussed.

The contribution of magnetic monopoles to the ponderomotive force

“…This is a hint indicating that, in the nonlinear regime, new ponderomotive forces [41] can appear exclusively due to the presence of magnetic monopoles. Similar analysis on the modification of ponderomotive forces in non-classical systems have been performed in semiconductor plasmas [42], quantum plasmas [43][44][45][46][47], spin quantum plasmas [48,49], and in electron-positron plasmas where the pair annihilation effects are important [50]. In all such cases the the non-classical effects introduce non-trivial corrections to ponderomotive forces.…”

Effects of quantum statistical pressure and exchange correlation on the low frequency electromagnetic waves in degenerate Fermi-Dirac pair-ion plasma

“…To study the dispersion properties of shear Alfvén wave (SAW) making a small angle with static external magnetic field B 0 = B 0 ẑ and propagating in a degenerate Fermi-Dirac pair-ion plasma, we write quantum Euler equations for the j species of electron positron and ion in quantum Fermi-Dirac plasmas [24]…”

“…Since the reported possible creation of dense electron-positron plasma, where the charged particles behave as a Fermi gas, and quantum mechanical effects might play a vital role in the dynamics of charge carriers. It is important to mention that the criterion of quantum interference of particles is satisfied by the lighter plasma particles (electrons and positrons) more easily alos the inclusion of the exchange-correlation potential with the quantum effects through the Bohmian force and the quantum statistical pressure may reflect the comprehensive study of a quantum plasma system [19][20][21][22][23][24][25][26]. The electron exchange and correlation effects in dense plasmas (by the electron half-spin particles) play a central role in the plasma dielectric response function [27].…”
