E. A. Carlen, M. C. Carvalho, R. Esposito, J. L. Lebowitz, R. Marra Free Energy Minimizers for a Two-Species Model with Segregation and Liquid-Vapor Transition (671K, Postscript) ABSTRACT. We study the coexistence of phases in a two--species model whose free energy is given by the scaling limit of a system with long range interactions (Kac potentials) which are attractive between particles of the same species and repulsive between different species
