Diffusion in ultracold strongly coupled multiply charged plasma: Calculation by molecular dynamics method

Abstract

We present the results of calculations of electron and ion diffusion by the method of molecular dynamics in an ultracold multiply charged plasma. The calculations were carried out in a wide range of Coulomb coupling parameter. The problems of similarity for a Coulomb multiply charged plasma are discussed. It is shown that in a multiply charged classical plasma for the diffusion coefficients in a wide range of coupling parameter, the similarity assumption is valid.
