“…due to photoelectric effects. There is a recent interest in how waves are modified by this change of dust charge sign and by the concomitant excess of electrons over protons (Sakanaka and Shukla, 2000;Mamun and Shukla, 2002;Baluku et al, 2008;Mamun, 2008).…”

Abstract. Large dust-acoustic solitons and kinks in dusty plasmas with positive cold dust, nonthermally distributed electrons and Boltzmann ions have been studied in a systematic way, to delimit their compositional parameter space. The existence domain of positive solitons is limited by infinite dust compression, of negative ones by the occurrence of potential kinks, provided the electrons are sufficiently nonthermal and there is sufficient positive charge on the dust. There is a parameter range where both negative and positive solitary structures coexist.

“…In addition non-stationary double layers could be potential accelerators for dust particles in space plasmas (see ref. [33]). This work can be extended to study the double layers in four compnent dusty plasma in presence non-thermal electrons or vortex like ions or vortex like electrons.…”

“…Sagdeev's [32] pseudo-potential method is one such method to obtain solitary wave solution. Using this method Sakanaka and Shukla [33], and Sakanaka and Iglika [34] studied Dust acoustic double layers (DADLs) in presence of charged dust grains. In their model they considered Boltzmann distributed ions.…”

Dust acoustic double layers are studied in a four component dusty plasma. Positively and negatively charged mobile dust and Boltzmann distributed electrons are considered. The ion distribution is taken as nonthermal. The existence of compressive and rarefractive double layers is studied by pseudopotential approach. The effect of non-thermal ions on small amplitude and arbitrary amplitude double layers are also studied.

“…But large-amplitude solitary waves and double layer also exist in nature and these were studied by several investigators [29,30] using Sagdeev's pseudopotential technique [31]. Sakanaka and Shukla [32] studied dust-acoustic double layers in the presence of charged dust grains.…”

Large-amplitude double layers in a dusty plasma with an arbitrary streaming ion beam

Formation of large-amplitude double layers in a dusty plasma whose constituents are electrons, ions, warm dust grains and positive ion beam are studied using Sagdeev's pseudopotential technique. Existence of double layers is investigated. It is found that both the temperature of dust particles and ion beam temperature play significant roles in determining the region of the existence of double layers.
