We use molecular dynamics (MD) and particle-in-cell (PIC) simulation methods to investigate the dispersion relation of dust-acoustic waves in a one-dimensional, strongly coupled (Coulomb coupling parameter = r = ratio of the Coulomb energy to the thermal energy = 120) dusty plasma. We study both cases where the dust is represented by a small number of simulation particles that form into a regul...

In a plasma containing charged dust grains, the dust acoustic instability (DAI) can be driven by ions streaming through the dust with speed less than the ion thermal speed. When the dust is strongly coupled in the liquid phase, the dispersion relation of the dust acoustic modes changes in a way that leads to an enhancement of the growth rate of the DAI. In this paper, we show how strong couplin...

An experimental investigation of dust acoustic ~DA! waves in a dc glow discharge plasma is described. The glow discharge is formed between a 3 cm anode disk and the grounded walls of a 60 cm diameter vacuum chamber which is filled with nitrogen gas at a pressure of about 100 mTorr. Dust located on a tray in the chamber is attracted into the plasma where it is trapped electrostatically. The dust...

The standard nonlinear Schrödinger Equation (NLSE) is one of the elegant equations to find detailed information about modulational instability criteria dust-ion-acoustic (DIA) waves and associated DIA rogue (DIARWs) in a three-component dusty plasma medium with inertialess super-thermal kappa distributed electrons, inertial warm positive ions negative dust grains. It can be seen that system sup...

A nonlinear Schr\"{o}dinger equation (NLSE) has been derived by employing reductive perturbation method for investigating the modulational instability of dust-ion-acoustic waves (DIAWs) in a four-component plasma having stationary negatively charged dust grains, inertial warm ions, and inertialess non-thermal electrons positrons. It is observed that under consideration, system supports both mod...

Ion-acoustic solitary and shock waves in dense quantum plasmas whose constituents are electrons, positrons, and positive ions are investigated. We assume that ion velocity is weakly relativistic and also the effects of kinematic viscosity among the plasma constituents is considered. By using the reductive perturbation method, the Korteweg–deVries–Burger (KdV-B) equation is derived. Keywords—Ion...
