Dust acoustic solitary waves in a dusty plasmas with nonthermal ions

Effect of obliqueness and external magnetic field on the characteristics of dust acoustic solitary waves in dusty plasma with two-temperature nonthermal ions

“…For example, Lin and Duan [8] considering the nonthermal ion in a dusty plasma derived a Korteweg-de Vries (KdV) equation for DA wave and it was found that the nonthermal ions have very important effect on the propagation of DA solitary waves. In a recent report Dorranian and Sabetkar [9] reported that with increasing nonthermal ion population, the amplitude of solitary wave decreases, while the width of solitary waves increases.…”

Auto-Backlund transformations and New Exact Soliton Solutions of KdV Equation for Nonlinear Dust Acoustic Solitary Waves in Dust Plasma with Variable Dust Charge

“…Substituting equations (13)(14)(15)(16)(17) into equations (1-4) and collecting terms with same powers of , from the cofficients of lowest order we have:…”

“…It was predicted that with the introduction of negative ions, there exists a critical ion concentration of negative ions below which compressive solitons exist and above which rarefactive solitons exist. Lin and Daun also considered dust acoustic solitary wave in a dusty plasma with non-thermal ions [14]. In this paper we we considered unmagnetized dusty plasma which including variation dust charge, Boltzmann distributed electrons and non thermal distributed ions.…”

Dust-Acoustic Solitary Waves in a Magnetized Dusty Plasma With Ions Of Distinct Temperatures

“…To explain the effects of nonthermal plasma species on the basic characteristics of the plasma system, containing fast nonthermal plasma species, Cairns et al [23]introduced a distribution function followed by those plasma species. After this pioneering work of Cairns et al a number of authors have studied the effects of nonthermal plasma species on different electrostatic propagation modes in a dusty plasma system containing negatively charged dust [5,24,25,27]. The above cited works [5,24,25,27] are confined to negatively charged dust and nonthermal ions or electrons of single temperature only.…”

But the existence of two-temperature ions [26,28,29,[31][32][33]41]or electrons [34,[36][37][38] which are common to occur in both space environments [36,39,40]and laboratory plasmas [35,36] are the topic of recent interest.…”
