First-order phase transition in a two dimensional BM3 model

The phase behavior of a Biroli-Mezard model on the two dimensional square lattice in which hard-core particles can have at most three nearest neighboring occupied sites is investigated by means of grand-canonical Monte Carlo simulations. Finite-size scaling analysis of relevant thermodynamic quantities obtained via the histogram reweighting technique reveals that at high-density, the model undergoes a first-order phase transition with preferential sublattice occupation to a crystal phase with enantiomorph ground state configurations, in close analogy to the hard-core lattice gas with the exclusion range extended up to the third shell of nearest neighbors.

Automated summary

The phase behavior of a Biroli-Mezard model on a two-dimensional square lattice was studied using Monte Carlo simulations. It was found that a first-order phase transition occurs at high density, leading to the formation of a crystal phase with enantiomorph ground state configurations.
