Equilibrium molecular dynamics simulations of the transport coefficients of the Yukawa one component plasma

Equilibrium molecular-dynamics simulations in the microcanonical ensemble have been performed to obtain the thermal conductivity and the two viscosities of the Yukawa one-component plasma from the Kubo formulas. The expressions of the Kubo currents (pressure tensor and energy current) which enter these formulas are derived in terms of Ewald sums. The simulation results for the transport coefficients are compared with the predictions of the Chapman–Enskog theory which has been solved numerically.
