Comment on ‘‘Self-Diffusion in 2D Dusty-Plasma Liquids: Numerical-Simulation Results’’ In a recent Letter [1], Hou, Piel, and Shukla (HPS) presented numerical results for the diffusion process in two-dimensional dusty-plasma liquids with Yukawa pair
is used to distinguish normal diffusion ( 1⁄4 0) from subdiffusion ( < 0) and superdiffusion ( > 0). HPS observed superdiffusion and reported a complicated nonmonotonic dependence of on the potential stiffness 1⁄4 a= , where a is the Wigner-Seitz radius. Here we point out that the behavior ð Þ is, in fact, regular and systematic, whereas the observations of Ref. [1] resulted from a comparison o...
متن کاملDusty Plasma Liquids
The dusty plasma liquid formed by micro-meter sized particles negatively charged and suspended in a low pressure discharge background is a good candidate to study the generic spatio-temporal dynamical behaviors at the kinetic level through direct optical video-microscopy, because of the sub-mm interparticle spacing and the slow time scale. In this paper, starting from the basic picture of the a...
متن کاملSelf-Diffusion of Dust Grains in Strongly Coupled Dusty Plasma Using Molecular Dynamics Simulation
In this paper diffusion of dust particles in strongly coupled dusty plasma is investigated by using molecular dynamics simulations. Self-diffusion coefficients of complex plasmas are obtained for a wide range of plasma parameters using Green-Kubo expression which is based on integrated velocity autocorrelation function (VACF). It is assumed that dust particles interact with each other by Yukawa...
متن کاملTwo-dimensional dusty plasma crystals and liquids
Strongly coupled plasmas – in which the average potential energy per particle dominates over the average kinetic energy – appear in a wide variety of physical systems. Among these systems, dust plasma crystals and liquids realized in low-pressure gas discharges by dispersing mesoscopic grains into the plasma have attracted a lot of attention during the past years. We describe the experimental r...
متن کاملWaves in two-dimensional superparamagnetic dusty plasma liquids.
Wave dispersion relations in the strongly coupled liquid phase of a two-dimensional system of dust grains interacting via both Yukawa and dipole interactions are investigated. The model system comprises a layer of charged superparamagnetic grains in a plasma in an external, uniform magnetic field B whose magnitude and direction can be varied. Because the induced magnetic dipole moments of the g...
