Energy density, heat capacity and diffusion constant in non-ideal Yukawa systems

Abstract

The energy densities, the heat capacities and the diffusion constants in two- and three-dimensional non-ideal dissipative systems of particles interacting with the screened Coulomb potential are studied. A simple semi-empirical expression for the energy density is considered. New analytical relations between the diffusion constants and the energy density in strongly coupled systems are proposed. Comparison of theoretical results and numerical simulations is presented.
