Nonlinear phenomena in screening of highly charged grains in plasmas

چکیده
Nonlinear effects in screening a highZ grain immersed in a plasma background were investigated by means of microscopic Monte-Carlo simulations and within the Poisson-Boltzmann theory. A distinct difference from the linear Debye-Hückel approximation was detected in the case of a strong plasma-grain coupling. It effected in the accumulation of the induced plasma charge on the grain surface, accompanied by a sharp enhancement of screening. The critical value of the parameter associated with the beginning of that plasma ’condensation’ was determined.

The Thomas-Fermi (TF) equation has proved to beuseful for the treatment of many physical phenomena. In this pa-per, the traveling wave solutions of the KdV equation is investi-gated by the simplest equation method. Also, the effect of differentparameters on these solitary waves is considered. The numericalresults is conformed the good accuracy of presented method.
متن کاملCompressive and rarefactive dust-ion acoustic solitary waves in four components quantum plasma with dust-charge variation
Based on quantum hydrodynamics theory (QHD), the propagation of nonlinear quantum dust-ion acoustic (QDIA) solitary waves in a collision-less, unmagnetized four component quantum plasma consisting of electrons, positrons, ions and stationary negatively charged dust grains with dust charge variation is investigated using reductive perturbation method. The charging current to the dust grains ca...
متن کاملDNLS Solitons in Collisional Dusty Plasma
Alfven waves are possible sources of turbulence in the interstellar medium. These waves are responsible for the transport of angular momentum and energy in the accretion discs. Such waves have been studied for last several decades in space plasmas. Most of the space plasmas are dusty. They contain charged grains and coupling of the grains to the magnetic field determines the wave propagation in...
متن کاملNonlinear excitations in Strongly-Coupled Plasma Lattices: Envelope solitons, kinks and Intrinsic Localized Modes
Ensembles of charged particles (plasmas) are a highly complex form of matter, most often modeled as a many-body system characterized by weak inter-particle interactions (electrostatic coupling). However, strongly-coupled plasma configurations have recently been produced in laboratory, either by creating ultra-cold plasmas confined in a trap or by manipulating dusty plasmas in discharge experime...
