DOI: 10.1103/PhysRevLett.94.1157010031-9007http://hdl.handle.net/10919/24494We present precision Monte Carlo data and analytic arguments for an asymmetric exclusion process, involving two species of particles driven in opposite directions on a 2xL lattice. To resolve a stark discrepancy between earlier simulation data and an analytic conjecture, we argue that the presence of a single macroscopic cluster is an intermediate stage of a complex nucleation process: in smaller systems, this cluster is destabilized while larger systems form multiple clusters. Both limits lead to exponential cluster size distributions, controlled by very different length scales.en-USIn Copyrightnonequilibrium steady-states3-state lattice-gasphase-transitionsexclusion processmodelsystemsringelectrophoresisdependencediffusionPhysicsArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevLett.94.115701https://doi.org/10.1103/PhysRevLett.94.115701
