Phase behavior of short-range square-well model.

Various Monte Carlo techniques are used to determine the complete phase diagrams of the square-well model for the attractive ranges λ=1.15 and λ=1.25. The results for the latter case are in agreement with earlier Monte Carlo simulations for the fluid-fluid coexistence curve and yield new results for the liquidus-solidus lines. Our results for λ=1.15 are new. We find that the fluid-fluid critical point is metastable for both cases, with the case λ=1.25 being just below the threshold value for metastability. We compare our results with prior studies and with experimental results for the γII-crystallin. [ABSTRACT FROM AUTHOR]
