Asymmetric Exclusion Processes under Diffusive Scaling
Consider the asymmetric exclusion process evolving on the lattice Z. This dynamics can be informally described as follows : fix a translation invariant transition probability p(x, y) = p(0, y− x) = p(y − x). Each particle, independently from the others, waits a mean one exponential time, at the end of which being at x it chooses the site x + y with probability p(y). If the chosen site is unoccu...
متن کاملTwo-Channel Totally Asymmetric Simple Exclusion Processes
Totally asymmetric simple exclusion processes, consisting of two coupled parallel lattice chains with particles interacting with hard-core exclusion and moving along the channels and between them, are considered. In the limit of strong coupling between the channels, the particle currents, density profiles and a phase diagram are calculated exactly by mapping the system into an effective one-cha...
متن کاملLocal inhomogeneity in asymmetric simple exclusion processes with extended objects
Totally asymmetric simple exclusion processes (TASEP) with particles which occupy more than one lattice site and with a local inhomogeneity far away from the boundaries are investigated. These non-equilibrium processes are relevant for the understanding of many biological and chemical phenomena. The steady-state phase diagrams, currents and bulk densities are calculated using a simple approxima...
متن کاملShocks in asymmetric simple exclusion processes of interacting particles.
In this paper, we study shocks and related transitions in asymmetric simple exclusion processes of particles with nearest-neighbor interactions. We consider two kinds of interparticle interactions. In one case, the particle-hole symmetry is broken due to the interaction. In the other case, particles have an effective repulsion due to which the particle current density drops down near one-half f...
متن کاملAsymmetric coupling in two-channel simple exclusion processes
Simple exclusion processes for particles moving along two parallel lattices and jumping between them are theoretically investigated for asymmetric rates of transition between the channels. An approximate theoretical approach, that describes the particle dynamics exactly in any vertical cluster of two parallel sites and neglects the correlations between the different vertical clusters, is applie...
