Dust-ion-acoustic solitons with transverse perturbation

Abstract

The ionization source model is considered, for the first time, to study the combined effects of trapped electrons, transverse perturbation, ion streaming velocity, and dust charge fluctuations on the propagation of dust-ion-acoustic solitons in dusty plasmas. The solitary waves are investigated through the derivation of the damped modified Kadomtsev–Petviashivili equation using the reductive perturbation method. Conditions for the formation of solitons as well as their properties are clearly explained. The relevance of our investigation to supernovae shells is also discussed.

Influence of arbitrarily charged dust and trapped electrons on propagation of localized dust ion-acoustic waves

“…It is clear that an increase of the trapping parameter β in the present dusty plasma with negative (positive) dust concentration leads to an increase of the potential depth, when the other parameters are held constant. In the case of negatively charged dust concentration, the result is similar to prior result with trapped electrons (Moslem et al 2005). This also confirms completely the result observed in Fig.…”

The dust ion acoustic waves propagation in collisional dusty plasmas with dust charge fluctuations: Effect of ion loss and ionization

“…To determine the value of ϕ (1) 0 , we let D = 0 in (19) and then it becomes the standard KdV equation and its solution is given by…”

The nonadiabatic dust charge variation on dust acoustic solitary and shock waves in strongly coupled dusty plasmas

“…The nonthermal distribution of electrons can be modeled by the Cairns distribution [44], while the distribution of free as well as trapped particles can be considered as prescribed by Schamel [45]. Accordingly the effects of nonthermal electrons [46][47][48][49][50] and trapped ions with vortex-like distribution [51][52][53][54] on the properties of electrostatic DA waves have been well studied in magnetized or unmagnetized plasma.…”
