“…The particle steady state is mainly provided by two forces: the electrostatic force, F = eZ d dϕ/dx, and the force due to the gradient of the internal 'electrostatic pressure', n −1 d dP d /dx, originating from the repulsion of similarly charged microparticles [12,14,23]. For Yukawa-type interacting strongly coupled grains, P d can be expressed in terms of an effective dust 'temperature' [14],…”

Abstract. The formation of a steady-state nonlinear potential structure of a double-layer type near the presheath/sheath edge of a plasma discharge is theoretically investigated in complex plasmas containing Boltzmann electrons, cold fluid ions and strongly coupled microparticles. Equilibrium of the particles is provided by the electrostatic force and an effective 'dust pressure' associated with electrostatic interactions between the highly charged grains. The results are of importance for complex plasma experiments in microgravity conditions, for thermophoretically levitated configurations and for processing plasmas loaded by nanometer-sized microparticles.

“…Another model which has recently been applied to study DAWs is the fluid approach presented by Gozadinos et al [14]. Drawing inspiration from previous space experiments [2,9], they developed a numerical model to simulate crystalline dusty plasmas under microgravity conditions.…”

“…Our aim here is to investigate linear and nonlinear dustacoustic waves in strongly coupled dusty plasmas. We account for strong coupling between the dust grains by using the model presented by Gozadinos et al [14], along with the electrostatic temperature approach of Yaroshenko et al [18]. The reductive perturbation method is employed to derive both the linear dispersion relation and the Korteweg-de Vries equation for this system.…”

Nonlinear dust-acoustic solitary waves in strongly coupled dusty plasmas

et al. 2012

Dust-acoustic waves are investigated in a three-component plasma consisting of strongly coupled dust particles and Maxwellian electrons and ions. A fluid model approach is used, with the effects of strong coupling being accounted for by an effective electrostatic "pressure" which is a function of the dust number density and the electrostatic potential. Both linear and weakly nonlinear cases are considered by derivation and analysis of the linear dispersion relation and the Korteweg-de Vries equation, respectively. In contrast to previous studies using this model, this paper presents the results arising from an expansion of the dynamical form of the electrostatic pressure, accounting for the variations in its value in the vicinity of the wave.

“…Gozadinos et al [10] presented a model for strongly coupled crystalline dusty plasmas, whereby the effects of strong coupling are accounted for via an electrostatic "pressure". This model, although originally developed for crystalline plasma structures, has recently been applied as an approximation to the equation of state for strongly coupled plasmas near to the liquid-crystal phase transition.…”

Dust-acoustic shocks in strongly coupled dusty plasmas

et al. 2014

Electrostatic dust-acoustic shock waves are investigated in a viscous, complex plasma consisting of dust particles, electrons, and ions. The system is modelled using the generalized hydrodynamic equations, with strong coupling between the dust particles being accounted for by employing the effective electrostatic temperature approach. Using a reductive perturbation method, it is demonstrated that this model predicts the existence of weakly nonlinear dust-acoustic shock waves, arising as solutions to Burgers's equation, in which the nonlinear forces are balanced by dissipative forces, in this case, associated with viscosity. The evolution and stability of dust-acoustic shocks is investigated via a series of numerical simulations, which confirms our analytical predictions on the shock characteristics.
