Free Energy Minimizers for a Two--Species Model with Segregation and   Liquid-Vapor Transition
  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.
