Using an adaptive, importance sampling Monte Carlo algorithm, the free energy and equation of state of a soft sphere solid are calculated. The Monte Carlo integration technique to be described is unlike standard methods in that it can evaluate directly the partition function and consequently the fre

โฆ Synopsis
Multiparticle Monte Carlo moves can be conveniently implemented for the simulation of hard-core solids, and are shown to significantly reduce computer time. A method for the calculation of the free energy with fully vectorized sampling is also presented. We discuss how the algorithm can be generalized to treat systems with continuous interactions and, possibly, less translational order than crystals.
