Abstract
Coexistence properties of the hard-core attractive Yukawa potential with inverse-range parameter k = 9, 10, 12, and 15 are calculated by applying canonical Monte Carlo simulation. As previously shown for longer ranges, we show that also for the ranges considered here the coexistence curves scaled by the critical density and temperature obey the law of corresponding states, and that a linear relationship between the critical density and the reciprocal of the critical temperature holds. The simulation results are compared to the predictions of the self-consistent Ornstein–Zernike approximation, and a good agreement is found for both the critical points and the coexistence curves, although some slight discrepancies are present.File | Dimensione | Formato | |
