A generalized Coulomb logarithm for strongly coupled plasmas

Plasma Physics 2011-12-05 v2

Abstract

Transport coefficients for Coulomb collision processes, e.g., friction, energy exchange, and resistivity, are calculated for Debye-screened (Yukawa) plasmas including correlation effects within the binary collision approximation. A generalized Coulomb logarithm, Ξ(Λ)\Xi(\Lambda), is required, which asymptotes to lnΛ\ln \Lambda in the weakly coupled limit, but is significantly modified when Λ102\Lambda \lesssim 10^2 due to large angle collisions. In the regime 102Λ10210^{-2} \lesssim \Lambda \lesssim 10^2, Ξ\Xi can be substantially larger for attractive collisions than repulsive.
