Particle-in-cell and reverse non-equilibrium molecular dynamics simulations are employed to estimate the electron thermal conductivity in a two-component plasma (TCP) consisting of electrons and protons. Simulations are performed over a range of Coulomb coupling parameters . For weakly coupled regimes ( the results show good agreement with the Landau–Spitzer and Lee–More models. Comparison with a one-component plasma, in which electrons are mobile and protons form a neutralizing background, reveals a systematic decrease of the electron thermal conductivity in the TCP. This reduction highlights the impact of ion interactions on electron heat transport.
