Elliptically polarized electromagnetic waves in a magnetized quantum electronpositron plasma with effects of exchangecorrelation
Abstract
The dispersion properties of elliptically polarized electromagnetic waves in a magnetized electronpositronpair (EPpair) plasma are studied with the effects of particle dispersion associated with the Bohm potential, the Fermi degenerate pressure, and the exchangecorrelation force. Two possible modes of the extraordinary or X wave, modified by these quantum effects, are identified and their propagation characteristics are investigated numerically. It is shown that the upperhybrid frequency and the cutoff and resonance frequencies are no longer constants but are dispersive due to these quantum effects. It is found that the particle dispersion and the exchangecorrelation force can have different dominating roles on each other depending on whether the X waves are of short or long wavelengths (in comparison with the Fermi Debye length). The present investigation should be useful for understanding the collective behaviors of EP plasma oscillations and the propagation of extraordinary waves in magnetized dense EPpair plasmas.

Within a quantum hydrodynamic model, the collective excitations of the quantum plasma with electron exchangecorrelation effects in a nanocylindrical wave guide are studied both analytically and numerically. The influences of the electron exchangecorrelation potential, the radius of the wave guide, and the quantum effect on the dispersion properties of the bounded quantum plasma are discussed. Significant frequencyshift induced by the electron exchangecorrelation effect, the radius of the wave guide and the quantum correction are observed. It is found that the influence of the electron exchangecorrelation, the radius of the wave guide and the quantum correction on the wave modes inmore »

Surface waves on quantum plasma halfspace with electron exchangecorrelation effects
The propagation of surface waves on a quantum plasma halfspace is investigated, taking into account the electron exchangecorrelation effect. Using the modified quantum hydrodynamic model in conjunction with the Poisson equation, the dispersion relation of surface waves is obtained. It is found that due to the presence of electron exchangecorrelation effect the wave frequency is shifted to lower frequencies. For different ranges of Brueckner parameter r{sub s}, the effect of electron exchangecorrelation is investigated. It is indicated that for weak coupling region with r{sub s} < 0.1, the wave frequency remains unchanged and in this region the effect of electron exchangecorrelation ismore »

The main differences between our work [H. Khalilpour, Phys. Plasmas 22, 122112 (2015)] and the work of Shahmansouri [Phys. Plasmas 22, 092106 (2015)] are summarized. Also, the validity of the prefactor 1/9 in front of Bohm potential is discussed. 
Effects of positron density and temperature on ionacoustic solitary waves in a magnetized electronpositronion plasma: Oblique propagation
Ionacoustic (IA) solitary waves are investigated in a magnetized threecomponent plasma consisting of cold ions, isothermal hot electrons, and positrons. The basic set of fluid equations is reduced to the Korteweg de Vries equation using the standard reductive perturbation (multiplescale) technique. Theoretical and numerical analyses confirm significant effects of the presence of positrons and the dependence of the electron to positron temperature ratio on the amplitude and the width of IA solitary waves. It is shown that the rarefactive and compressive IA solitary excitations can propagate when the propagation angle {theta} satisfies 0{<=}{theta}<{pi}/2 and {pi}/2<{theta}{<=}{pi}, respectively. Also, it is remarkedmore » 
Envelope solitons of electromagnetic waves in a magnetized electronpositron plasma
The propagation of a linearly polarized nonlinear electromagnetic wave parallel to a magnetic field in an electronpositron plasma is considered. Both convection and ponderomotive linearities are considered, as well as the relativistic character of the motion of the plasma particles in the wave field, to second order in the field amplitude. Conditions are obtained for the existence of soliton perturbations in various regimes. 11 refs.
