A generalized Coulomb logarithm for strongly coupled plasmas

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, $\mathrm{\Xi }(\mathrm{\Lambda })$, is required, which asymptotes to $\ln \mathrm{\Lambda }$ in the weakly coupled limit, but is significantly modified when $\mathrm{\Lambda }\lesssim {10}^2$ due to large angle collisions. In the regime ${10}^{-2}\lesssim \mathrm{\Lambda }\lesssim {10}^2$, $\mathrm{\Xi }$ can be substantially larger for attractive collisions than repulsive.
