Kinetic theory of the filamentation instability in a collisional currentdriven plasma with nonextensive distribution
Abstract
The evolution of filamentation instability in a weakly ionized currentcarrying plasma with nonextensive distribution was studied in the diffusion frequency region, taking into account the effects of electronneutral collisions. Using the kinetic theory, Lorentz transformation formulas, and BhatnagarGrossKrook collision model, the generalized dielectric permittivity functions of this plasma system were achieved. By obtaining the dispersion relation of lowfrequency waves, the possibility of filamentation instability and its growth rate were investigated. It was shown that collisions can increase the maximum growth rate of instability. The analysis of temporal evolution of filamentation instability revealed that the growth rate of instability increased by increasing the qparameter and electron drift velocity. Finally, the results of Maxwellian and qnonextensive velocity distributions were compared and discussed.

The filamentation and ion acoustic instabilities of nonextensive currentdriven plasma in the ion acoustic frequency range have been studied using the Lorentz transformation formulas. Based on the kinetic theory, the possibility of filamentation instability and its growth rate as well as the ion acoustic instability have been investigated. The results of the research show that the possibility and growth rate of these instabilities are significantly dependent on the electron nonextensive parameter and drift velocity. Besides, the increase of electrons nonextensive parameter and drift velocity lead to the increase of the growth rates of both instabilities. In addition, the wavelength regionmore »

Kinetic theory on the currentfilamentation instability in collisional plasmas
The current filamentation instability (CFI) or Weibeltype instability is studied for a nonrelativistic electron beam penetrating an infinite uniform plasma, taking into account both the collisional effects and the spacecharge effect (SCE). We consider three configurations for the beam and plasma: the kinetic domain, the hydrodynamic domain, and the hybrid domain with one in kinetic and the other in hydrodynamic domain. It is shown that the CFI is determined by the currentdriven driftanisotropy rather than the classical anisotropy of the beam and the background plasma. Therefore, collisional effects can either attenuate or enhance the CFI depending on the driftanisotropy ofmore » 
Filamentation instability of currentdriven dust ionacoustic waves in a collisional dusty plasma
A theoretical investigation has been made of the dust ionacoustic filamentation instability in an unmagnetized currentdriven dusty plasma by using the Lorentz transformation formulas. The effect of collision between the charged particles with neutrals and their thermal motion on this instability is considered. Developing the filamentation instability of the currentdriven dust ionacoustic wave allows us to determine the period and the establishment time of the filamentation structure and threshold for instability development. 
Particle in cell simulations of Buneman instability of a currentdriven plasma with qnonextensive electron velocity distribution
The nonlinear evolution of low frequency Buneman instability in an unmagnetized currentdriven plasma with qnonextensive electron velocity distribution is investigated using particle in cell simulation. Simulation results show that the generation of electron phase space holes and the counterstreaming current induced in the plasma strongly depend on the qparameter. It is found that by increasing the nonextensive parameter, the distribution of electron density becomes highly peaked. This density steepening or gratinglike pattern occurs at the saturation time. In addition, a generalized dispersion relation is obtained using the kinetic theory. Analysis of the dispersion relation and the temporal evolution of themore » 
Nonlinear Raman forward scattering driven by a short laser pulse in a collisional transversely magnetized plasma with nonextensive distribution
Nonlinear Raman forward scattering of an intense short laser pulse with a duration shorter than the plasma period propagating through a homogenous collisional nonextensive distributed plasma in the presence of a uniform magnetic field perpendicular to both the direction of propagation and electric vector of the radiation field is investigated theoretically when ponderomotive, relativistic, and collisional nonlinearities are taken into account. The governing equations for nonlinear wave in the context of nonextensive statistics are given, the nonextensive coupled equations describing the nonlinear Raman forward scattering instability are solved by the Fourier transformation method, and the growth rate of the nonlinearmore »
