“…This prediction was soon verified in plasma discharges [6][7][8], and strongly coupled plasmas have since become a popular research area among plasma physicists. The large masses of the dust particles can cause complications when studying strongly coupled dusty plasmas on earth-based experiments.…”

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.

“…The first is to put them in a trap, that is, to add an external potential N j=1 V ext (x j ) to the energy, with V ext (x) → +∞ when |x| → ∞. This is now done in the laboratory [56,128,230,231], although a large number of particles is still difficult to reach. We discuss this possibility in Section 2.7.1 below.…”

In this article we describe the crystallization conjecture. It states that, in appropriate physical conditions, interacting particles always place themselves into periodic configurations, breaking thereby the natural translation-invariance of the system. This famous problem is still largely open. Mathematically, it amounts to studying the minima of a real-valued function defined on R 3N where N is the number of particles, which tends to infinity. We review the existing literature and mention several related open problems, of which many have not been thoroughly studied.

“…A longlived controversy was ignited by the suggestion [5] that like-charged macroparticles need not repel each other as predicted by PoissonBoltzmann (PB) mean field theory [6][7][8][9][10][11][12][13]. In the area of dust plasmas, one can observe transitions from a disordered gaseous-like phase to a liquid-like phase and the formation of ordered structures of particles-plasma crystals [14][15][16][17]. The wake effect has been proposed as the most promising candidate for the formation of the dust-plasma crystals [18,19], and it was experimentally confirmed to be responsible for the attraction of two macroparticles by optical manipulations using radiation pressure from laser light [20,21].…”

Abstract-The anisotropic spherical Wigner-Seitz (WS) cell model -introduced to describe colloidal plasmas -is investigated using the linearized Poisson-Boltzmann (PB) equation. As an approximation, the surface potential of the spherical macroparicle expanded in terms of the monopole (q) and the dipole (p) is considered as an anisotropic boundary condition of the linear PB equation. Here, the "apparent" moments q and p are the moments 'seen' in the microion cloud, respectively. Based on a new physical concept, the momentneutrality, the potential around the macroparticle can be solvable analytically if the relationship between the actual moment and the "apparent" moment can be obtained according to the momentneutrality condition in addition to the usual electroneutrality. The calculated results of the potential show that there is an attractive region in the vicinity of macroparticle when the corresponding dipole part of the potential dominates over the monopole part, and there is an attractive region and a repulsive region at the same time, i.e., a potential well, when the corresponding dipole part of the potential just comes into play. It provides the possibility and the conditions of the appearance of periodic structure of the colloidal plasmas, although it is a result of a simple theoretical model.
