We study the continuum Widom-Rowlinson model of interpenetrating spheres. Using a new geometric representation for this system we provide a simple percolation-based proof of the phase transition. We also use this representation to formulate the problem, and prove the existence of an interfacial tension between coexisting phases. Finally, we ascribe geometric (i.e. probabilistic) significance to the correlation functions which allows us to prove the existence of a sharp correlation length in the… Expand
The Widom-Rowlinson Model on the Delaunay Graph
We establish phase transitions for continuum Delaunay multi-type particle systems (continuum Potts or Widom-Rowlinson models) with infinite range repulsive interaction between particles of differentExpand
A Curie-Weiss theory of the continuum Widom-Rowlinson model
Abstract A version of the continuum Widom–Rowlinson model is introduced and studied. It is a two-component gas of point particles placed in R d in which like particles do not interact and unlikeExpand

Gibbs-non Gibbs transitions in different geometries: The Widom-Rowlinson model under stochastic spin-flip dynamics
The Widom-Rowlinson model is an equilibrium model for point particles in Euclidean space. It has a repulsive interaction between particles of different colors, and shows a phase-transition at highExpand

We study the critical droplet for a close-to-equilibrium Widom-Rowlinson model of interacting particles in the two-dimensional continuum at low temperatures. The critical droplet is the set ofExpand
A phase transition in a Widom–Rowlinson model with Curie–Weiss interaction
An analog of the continuum Widom-Rowlinson model is introduced and studied. Its two-component version is a gas of point particles of types 0 and 1 placed in $\mathds{R}^d$, in which like particles doExpand
Random-Cluster Analysis of a Class of Binary Lattice Gases
We introduce a class of binary lattice gases which can be viewed as a lattice analogue of the continuum Widom–Rowlinson model, and which also is related to the beach model of Burton and Steif. ThisExpand
Surface order large deviations of phase interfaces for the continuum Widom-Rowlinson model in high density limit

Dynamical Gibbs-non-Gibbs transitions in Curie-Weiss Widom-Rowlinson models
We consider the Curie-Weiss Widom-Rowlinson model for particles with spins and holes, with a repulsion strength beta between particles of opposite spins. We provide a closed solution of the model,Expand
Phase transitions and the random-cluster representation for Delaunay Potts models with geometry-dependent interactions
We investigate the existence of phase transitions for a class of continuum multi-type particle systems. The interactions act on hyperedges between the particles, allowing us to define a class ofExpand
