Conductivity and diffusion coefficients in fully ionized strongly coupled plasma: Method of molecular dynamics

Abstract

We present the results of calculations of diffusion coefficients and electrical conductivity of ultracold single and multiply charged plasma by the method of molecular dynamics. The calculations are carried out in a wide range of Coulomb coupling parameters. We thus gain access to fundamental aspects of strongly coupled plasmas under conditions where experimental measurements are difficult. The results obtained for our model can be used for any equilibrium or nonequilibrium strongly coupled plasmas, in which quantum effects are negligible. Comparison with experimental data is made. Theoretical and experimental results are in good agreement. It is shown that the law of similarity for Coulomb systems is valid in a wide region of coupling.
