A complex plasma medium (containing Cairns nonthermal electron, adiabatically warm inertial ion, and stationary positively charged dust (PCD) species (making a system very complex) is considered. The effects of PCD species, electron adiabatic ion-temperature on ion-acoustic (IA) solitary waves (SWs) double layers (DLs) are investigated by the pseudo-potential approach, which valid for arbitrary...

Repeated, self-excited dust acoustic shock waves (DASWs) have been observed in a dc glow discharge dusty plasma using high-speed video imaging. Two major observations are reported: (1) The self-steepening of a nonlinear dust acoustic wave (DAW) into a saw-tooth wave with sharp gradient in dust density, very similar to those found in numerical solutions of the fully nonlinear fluid equations for...

We have considered an unmagnetized dusty plasma system consisting of ions obeying superthermal distribution and strongly coupled negatively charged dust. We have used reductive perturbation method and derived the Kordeweg-de Vries-Burgers (KdV-Burgers) equation. The behavior of the shock waves in the plasma has been investigated. Keywords—Shock, Soliton, Coupling, Superthermal ions.

Energetic heavy ions with short duration can be generated in the interaction of ultrashort ultraintense (USUI) laser pulse solid matter. However, energy conversion efficiency from to is usually very low. Herein, a novel scheme for efficient transfer USUI microscopic dust grains dusty plasma proposed. Due resulting space-charge field, expand isotropically together heated and expelled grain elect...

Charging mechanism of dust particles in a nonuniform discharge plasma under cryogenic environment is studied theoretically. The plasma density and temperature effects on dust grain charging are investigated with characteristic time scales of density variation and temperature relaxation in consideration. The charge of a dust grain, initially placed in a discharge plasma and cooled to cryogenic t...

We consider the nonlinear ion-acoustic wave induced by orbiting charged space debris in plasma environment generated at Low Earth Orbital (LEO) region. The is shown to be governed forced Korteweg-de Vries equation with forcing function dependent on function. For a specific relationship between and wave, KdV turns completely integrable system where obeys definite non-holonomic constraint. A spec...

We theoretically investigate conditions for the refraction of long-wavelength dust acoustic waves by arrays of periodic cylinders in a dusty plasma. This is based on a recent analysis of the refraction of shallow water waves by periodic cylinder arrays (Hu and Chan, Phys. Rev. Lett. 95 (2005), 154501). In the dusty plasma case, however, the boundary conditions involve the formation of voids aro...
