Ground state of a confined Yukawa plasma including correlation effects.
The ground state of an externally confined one-component Yukawa plasma is derived analytically using the local density approximation (LDA). In particular, the radial density profile is computed. The results are compared with the recently obtained mean-field (MF) density profile [Henning et al., Phys. Rev. E 74, 056403 (2006)]. While the MF results are more accurate for weak screening, the LDA w...
متن کاملSpectral properties of spherically confined dusty plasma crystals
Spherically confined dust crystals have recently attracted large attention, see e.g. [1] and [2] for an overview. After the exploration of the ground state structure [3, 4, 5, 6] and of metastable states and their probability [7, 8, 9] a question of particular interest is the dynamical excitation spectrum. The normal modes are a key property describing the response of a finite system to externa...
متن کاملThermodynamics of a two-dimensional Yukawa fluid.
Thermodynamic quantities of a two-dimensional Yukawa system, a model for various systems including single-layered dust particles observed in dusty plasmas, are obtained and expressed by simple interpolation formulas. In the domain of weak coupling, the analytical method based on the cluster expansion is applied and, in the domain of intermediate and strong coupling, numerical simulations are pe...
متن کاملTHE DENSITY PROFILES OF A LENNARD -JONES FLUID CONFINED TO A SLIT
The structure of fluids confined by planar walls is studied using density functional theory. The density functional used is a generalized form of the hypernetted chain (HNC) functional which contains a term third order in the density. This term is chosen to ensure that the modified density functional gives the correct bulk pressure. The proposed density functional applied to a Lennard-Jones...
متن کاملSimulation of a Helium Atmospheric Plasma Jet Using Fluid Equations
In this study, a cold atmospheric He plasma jet is investigated. The jet is of dielectric barrier discharge type, consisting of a dielectric tube with two metal ring electrodes. The continuity, momentum and energy conservation equations as well as the Poisson equation for obtaining the potential and the electric field, accompanied with the ideal gas laws, are used for the simulation. The result...
