Title: Discontinuous Phase Transitions in Nonlocal Schloegl Models for Autocatalysis: Loss and Reemergence of a Nonequilibrium Gibbs Phase Rule

Abstract

Here, we consider Schloegl models (or contact processes) where particles on a square grid annihilate at a rate p and are created at a rate of k n=n(n–1)/[ N( N–1)] at empty sites with n particles in a neighborhood Ω N of size N. Simulation reveals a discontinuous transition between populated and vacuum states, but equistable p=p eq determined by the stationarity of planar interfaces between these states depends on the interface orientation and on Ω N of size N. The behavior for large Ω N of size N follows from continuum equations. These also depend on the interface orientation and on Ω N of size N shape, but a unique p eq=0.211 376 320 4 emerges imposing a Gibbs phase rule.
