Thermal conductivity of the classical electron one-component plasma

We carried out molecular dynamics experiments to determine the reduced heat diffusion coefficient D-th and the reduced thermal conductivity lambda of the three-dimensional classical electron one-component plasma, for the 1 less than or equal to Gamma less than or equal to 20 range of the plasma coupling parameter Gamma. In our simulations the temperature of the system was spatially modulated, and D-th and lambda were calculated from the relaxation time of the temperature profile. D-th was found to decrease with increasing Gamma, while lambda decreased with increasing Gamma for Gamma less than or equal to 4 (from lambda congruent to 2.3 at Gamma = 1.1 to lambda congruent to 0.6 at Gamma = 4) and was approximately constant (lambda congruent to 0.4) in the 8 less than or equal to Gamma less than or equal to 20 range.
