Reentrant condensation transition in a two species driven diffusive system

Statistical Mechanics 2017-03-06 v3

Abstract

We study an interacting box-particle system on a one-dimensional periodic ring involving two species of particles AA and BB. In this model, from a randomly chosen site, a particle of species AA can hop to its right neighbor with a rate that depends on the number of particles of the species BB at that site. On the other hand, particles of species BB can be transferred between two neighboring sites with rates that depends on the number of particles of species BB at the two adjacent sites-this process however can occur only when the two sites are devoid of particles of the species AA. We study condensation transition for a specific choice of rates and find that the system shows a reentrant phase transition of species AA - the species AA passes successively through fluid-condensate-fluid phases as the coupling parameter between the dynamics of the two species is varied. On the other hand, the transition of species BB is from condensate to fluid phase and hence does not show reentrant feature.
