Weakly dissipative dust-ion-acoustic solitons in complex plasmas and the effect of electromagnetic radiation

Abstract

Possibility for dust ion-acoustic solitons to exist in complex (dusty) plasmas in the presence of electromagnetic radiation, which results in positive dust particle charges, is investigated. Dissipative processes occurring during the propagation of dust ion-acoustic perturbations, among which are the charging of dust grains, the absorption of ions by grains, the transfer of the ion momentum to the grains, and ion-neutral collisions, are taken into account. Temporal evolution of the soliton-like perturbation and interaction of two soliton-like perturbations are studied. Compressive soliton-like perturbations are shown to possess the main properties of the soltons, in particular, the interacting perturbations conserve their form.

The effect of dust size distribution on the damping of the solitary waves in a dusty plasma

“…m i and m dj are the masses of the ions and the jth dust grains, respectively. The ion momentum loss is due to collisions with microparticles and is determined by the ion momentum-transfer frequency id , 24,25 where id is the collision frequency between the ions and the dust particles. However, in the present paper, we consider the dust size distribution effect, id is different with different dust particles.…”

Dust ion acoustic solitary waves in a collisional dusty plasma with dust grains having Gaussian distribution

“…Using simulations of basic equations, Losseva et al 21,22 investigated the possibility for arbitrary amplitude dust ion acoustic soliton like perturbation in dusty plasmas. They also reported about the interaction of two soliton like perturbations.…”

Modulation instability and dissipative rogue waves in ion-beam plasma: Roles of ionization, recombination, and electron attachment

“…Therefore, it is important to investigate the effect of these relevant processes on the collective behavior in plasma systems. [21][22][23] It is well-known that the velocity distribution of electrons has a great influence on wave motions in plasmas. In the past few decades, the classical Maxwellian particle distribution has been the most commonly used velocity distribution.…”
