Dust particles in a nuclear-induced plasma

Small systems of laser-driven active Brownian particles: Evolution and dynamic entropy

“…These charged grains effectively interact between each other as well as with external electrical and/or magnetic fields. The action of external forces and forces of interparticle interaction combined with dissipative mechanisms in these systems can lead to the selforganization of the system, resulting in the formation of quasi-stationary dusty plasma systems as well as to complex oscillatory or chaotic regimes [33][34][35][36][37][38][39][40][41][42][43]. An essential characteristic of dust structures in laboratory gas discharges is that these systems are far from equilibrium.…”

Simulation of mass transport in systems with repulsive isotropic pair potential

“…Also significant are the potentials simulating the screening that weakens with the distance; this situation was predicted in some theoretical and experimental works [16][17][18][19]. For example, it is common to assume that the behaviour of a potential on large distances from the dusty grain, r λ, has the power asymptotics: U ∝ r −2 [18] or U ∝ r −3 [19]; thus, the potential parameters in (11) will be κ 1 = l p /λ, κ 2 = 0, n = 1-2 and a 1 a 2 , respectively.…”

“…the propagation of the shock waves and impulse actions, or progression of the edge of chemical transformations in condensed matter [5,10]). On the other hand, it is necessary for the analysis of transport features of strongly dissipative nonideal media (such as colloidal solutions, plasma of combustion products and nuclear-induced high-pressure dusty plasma [2,11]), where the long-term experiments should be carried out to measure the diffusion coefficient correctly.…”

Mass-Transfer in the Dusty Plasma as a Strongly Coupled Dissipative System: Simulations and Experiments

“…A study of the mass-transfer processes on short observation times is especially important for investigation of fast processes (e.g. the propagation of shock waves and impulse actions, or progression of front of chemical transformations in condensed matter (Ovchinnikov et al, 1989;Dodd et al, 1982)), and also for the analysis of transport properties of strongly dissipative media (such as colloidal solutions, plasma of combustion products, nuclear-induced high-pressure dusty plasma (Cummins & Pike, 1974;Fortov et al, 1996;Fortov et al, 1999)), where the long-term experiments should be carried out to measure the diffusion coefficients correctly.…”

“…The problems associated with the mass-transfer processes in dissipative systems of interacting particles are of great interest in various fields of science (plasma physics, medical industry, physics and chemistry of polymers, etc.) (Frenkel, 1946;Cummins & Pike, 1974;Balescu, 1975;March & Tosi, 1995;Ovchinnikov et al, 1989;Dodd et al, 1982;Thomas & Morfill, 1996;Fortov et al, 1996;Fortov et al, 1999). Nevertheless, the hydrodynamic approaches can successfully describe these processes only in the case of the short-range interactions between particles.…”
