The statistical properties of the interfaces for the lattice Widom–Rowlinson model

AbstractWe investigate the statistical properties of the fluctuations of the phase interfaces that separate two phases of the two-dimensional lattice Widom–Rowlinson model. When the chemical potential μ of the W–R model is large enough, we discuss the probability distributions which describe the fluctuations of the phase interfaces, and show the corresponding central limit theory for the two-dimensional lattice W–R model
