“…[2][3][4] In recent years, the researches on the complex plasmas with power-law distributions have attracted great interest because their many interesting applications are found in the wide fields of space plasma physics and astrophysics, and also because the power-law distributions observed in plasmas can be studied under the framework of nonextensive statistics. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] And with the aid of the nonextensive kinetic theory, one can determine the expressions of the nonextensive q-parameter in the astrophysical and space plasmas 29 and thereby understand its physical meaning.…”

We study the viscosity of light charged particles in weakly ionized plasma with the power-law q-distributions by using the Boltzmann equation of transport and the motion equation of hydrodynamics. The nonequilibrium plasma is considered to be space inhomogeneous and without magnetic field. We derive the expressions of the viscosity coefficients of the electrons and the ions in the q-distributed plasma, including the first and the second viscosity coefficients respectively. It is shown that these new viscosity coefficients depend strongly on the q-parameters, and when we take q→1, they perfectly return to those in the plasma with a Maxwellian distribution. The discussions presented in this paper can also be applied to the plasmas with the kappa-distributions.1 1

“…Khrapak et al [11] have investigated the effect of the polarization force on the propagation of the DA solitary waves. During the past years, a series of theoretical studies has been performed to investigate the propagation characteristics of the DA waves in the presence of the polarization force acting on dust grains in a background of non-uniform plasmas [12][13][14][15][16]. Most of these investigations have been published by assuming negatively charged massive dust grains due to the collection of electrons from background of plasma species.…”

The propagation and collision of dust acoustic (DA) multi-solitons in a four component dusty plasma which consists of negatively and positively charged cold dust fluids, Boltzmann distributed electrons and ions have been studied in the presence of a polarization force acting on dust grains. Using the reductive perturbation technique (RPT), the Korteweged-de Vries (KdV) equation is derived. By using the Hirota bilinear method, the two-and three-soliton solutions of the obtained KdV equation have been successfully obtained. Phase shifts of the two-soliton and three-soliton have been deduced. It has been found that both compressive and rarefactive solitons exist in current dusty plasma model. The polarization force plays a significant role in the overtaking collision process of two-soliton and three-soliton, in such a way that the amplitude of the compressive (rarefactive) solitons decreases (increases) as polarization force increases. It was also found that the phase shifts are significantly affected by the dusty plasma parameters such as the dust charge number ratio, ion-to-electron temperature ratio, negative-to-positive dust mass ratio, the ratio of the densities of electrons to ions and the polarization force parameter.

“…Therefore, the pressure of Fermi gas is non-zero even at zero temperature (against a classical ideal gas). This effect is called the degeneracy pressure (Dyson & Lenard 1967). Indeed the Pauli exclusion principle, through the creation of an emergent pressure, disallows compression of matter into smaller volumes of space.…”

Breather structures in degenerate relativistic non-extensive plasma

2017

View full text Add to dashboard Cite

We examine the excitation of breather structures in a degenerate relativistic plasma consisting of non-extensive electrons and cold ions. For this purpose, the multiple time scale perturbation technique is used to obtain a nonlinear Schrödinger equation (NLSE). We then consider different localized solutions regarding analytical breather solutions of the NLSE, and examine their properties in the frame of the present plasma system, i.e. a degenerate relativistic non-extensive plasma. The results of the present investigation may be useful for the understanding of the basic features of the nonlinear excitations that may occur in dense astrophysical plasmas.
