Freezing of Yukawa Systems Near the One-Component-Plasma Limit
It is shown that the Yukawa freezing results as obtained recently by Farouki and Hamaguchi [J. Chem. Phys. 101, 9885 (1994)] using molecular dynamics simulations contradict the Monte Carlo results of Meijer and Frenkel [J. Chem. Phys. 94, 2269 (1991)], the molecular dynamics results of Stevens and Robbins [J. Chem. Phys. 98, 2319 (1993)], as well as several empirical freezing criteria. A systematic inquiry finally identified the cause for the Farouki and Hamaguchi incorrect result, and solved the discrepancy. The present analysis provides the corrected freezing line for Yukawa systems in the weak screening region, near the one-component-plasma limit.
