Reply toShort-range screening potentials for classical Coulomb fluids: Reanalysis of Monte Carlo sampling and cluster model studies
No full textThe model reanalyses on the screening potential (SP) for the classical one-component plasmas, presented by Rosenfeld [preceding paper, Phys. Rev. E 52, 2000 (1995)] have been re-examined in light of the Monte Carlo (MC) simulation data currently available. With due consideration of statistical uncertainties in the MC data, it is shown that these approximation schemes individually may not corroborate some of the MC data. The assessed value (h2/Γ=0.00±0.01) [Ichimaru et al., Phys. Rev. E 50, 2977 (1994)] of the quartic coefficient in the short-range expansion of the SP is consistent with all the data obtained by the first-principles direct MC samplings of h2 and can reproduce MC values of the radial distribution function and SP uniformly for 10 ? Γ ? 160.journal articl
Reply to Comment on Equation of state and phase diagrams for dense multi-ionic mixture plasmas
No full textExcess internal energies of binary-ionic mixture (BIM) plasmas containing small concentrations of larger-charge ions are reexamined critically. Through examination of the fitting formulas advanced for the energies of the one-component plasmas (OCPs), we show that the sign of the deviations for the BIM energies from the linear mixing values cannot be determined from Monte Carlo simulation data for the energies alone. Instead, the sum rule with respect to the OCP screening potential at the origin is shown to be useful in judging the sign of the deviations. By using the best values currently available for the screening potential, we find that the deviations take on negative values in accordance with the prediction by Ogata, Iyetomi, Ichimaru, and Van Horn [Phys. Rev. E 48, 1344 (1993)].journal articl
