title: Condensation and evaporation of mutually repelling particles: Steady states and limit cycles.
abstract: We study condensation and evaporation of particles which repel each other. The system evolves through a computer simulation using a simple set of rules on a square lattice. Different results are obtained for a mobile and an immobile surface layer. A two point limit cycle is observed for high temperature and pressure in both cases. Here the coverage oscillates between a high and a low value without ever reaching a steady state. The results for the immobile case depend in addition on the initial coverage.
