Equation of state for hard-square lattice gases.
A simple equation of state is derived for a hard-core lattice gas of side length lambda , and compared to the results of Monte Carlo simulations. In the disordered fluid phase, the equation is found to work very well for a two-dimensional lattice gas of hard squares and reasonably well for the three-dimensional gas of hard cubes.
