Summary

This study determined phase diagrams for the square-well model using Monte Carlo simulations. New liquidus-solidus lines were found, and the fluid-fluid critical point was identified as metastable for both attractive ranges.

Background:

Phase diagrams are crucial for understanding material behavior.
The square-well model is a fundamental model in statistical mechanics.
Previous studies have explored fluid-fluid coexistence but lacked detailed solidus lines.

Purpose of the Study:

To compute complete phase diagrams for the square-well model at attractive ranges lambda = 1.15 and 1.25.
To investigate the metastability of the fluid-fluid critical point.
To compare simulation results with existing literature and experimental data for gamma(II)-crystallin.

Main Methods:

Advanced Monte Carlo simulation techniques were employed.
The simulations focused on determining the boundaries of different phases.
Analysis included identifying fluid-fluid coexistence and liquidus-solidus lines.

Main Results:

Complete phase diagrams were generated for lambda = 1.15 and 1.25.
Results for lambda = 1.25 align with prior fluid-fluid coexistence data and provide new liquidus-solidus lines.
New phase diagram results were obtained for lambda = 1.15.
The fluid-fluid critical point was found to be metastable in both cases.
The lambda = 1.25 case was near the metastability threshold.

Conclusions:

The study successfully mapped the phase behavior of the square-well model for specific attractive ranges.
Metastability of the critical point was confirmed, offering insights into phase transitions.
The findings provide a foundation for further theoretical and experimental investigations, including comparisons with biological systems like gamma(II)-crystallin.
