Critical phenomena of the hard-sphere lattice gas on the simple cubic lattice

Abstract

We study the critical phenomena of the hard-sphere lattice gas on the simple cubic lattice with nearest neighbour exclusion by the Monte Carlo method. We get the critical exponents, $\beta / \nu$ = 0.313(9) and $\gamma / \nu$ = 2.37(2), where $\beta$ is the critical exponent for the staggered density, $\gamma$ for the staggered compressibility, and $\nu$ for the correlation length.
