Abstract

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