A simple two-species asymmetric exclusion model is introduced. It consists of two types of oppositely charged particles driven by an electric field and hopping on an open chain. The phase diagram of the model is calculated in the meanfield approximation and by Monte Carlo simulations. Exact solutions are given for special values of the parameters defining its dynamics. The model is found to exhibit two phases in which spontaneous symmetry breaking takes place, where the two currents of the two… 
Spontaneous symmetry breaking in a non-conserving two-species driven model
A two-species particle model on an open chain with dynamics which is non-conserving in the bulk is introduced. The dynamical rules which define the model obey a symmetry between the two species. The
One-dimensional asymmetric exclusion model with open boundaries
One-dimensional asymmetric exclusion model, in which the probabilities of hopping to the left and right are in general different, is studied. The boundaries are open; a particle is added at the left
Asymmetric simple exclusion model with local inhomogeneity
We study a totally asymmetric simple exclusion model with open boundary conditions and a local inhomogeneity in the bulk. It consists of a one-dimensional lattice with particles hopping
A Two-Species Exclusion Model With Open Boundaries: A use of q-deformed algebra
In this paper we study an one-dimensional two-species exclusion model with open boundaries. The model consists of two types of particles moving in opposite directions on an open lattice. Two adjacent
Spontaneous symmetry breaking in two-channel asymmetric exclusion processes with narrow entrances
Multi-particle non-equilibrium dynamics in two-channel asymmetric exclusion processes with narrow entrances is investigated theoretically. Particles move on two parallel lattices in opposite
The exact phase diagram for a class of open multispecies asymmetric exclusion processes
This work considers a totally asymmetric exclusion process with multiple species of particles on a one-dimensional lattice in contact with reservoirs, and derives the exact nonequilibrium phase diagram for the system in the long time limit.
Dynamical aspects of spontaneous symmetry breaking in driven flow with exclusion.
A numerical study of a two-lane version of the stochastic nonequilibrium model known as the totally asymmetric simple exclusion process, which studies an adaptation of domain-wall theory to mimic the density reversal process associated with a flip.
Shocks in the asymmetry exclusion model with an impurity
We consider the one-dimensional asymmetric exclusion process with an impurity. This model describes particles hopping in one direction with stochastic dynamics and a hard core exclusion condition.


Finite-size effects for phase segregation in a two-dimensional asymmetric exclusion model with two species
We investigate the stationary states of a two-dimensional lattice gas model with exclusion, in the presence of an external field. The lattice is populated by equal numbers of positively and
Phase transitions in an exactly soluble one-dimensional exclusion process
We consider an exclusion process with particles injected with rate α at the origin and removed with rate β at the right boundary of a one-dimensional chain of sites. The particles are allowed to hop
An exact solution of a one-dimensional asymmetric exclusion model with open boundaries
A simple asymmetric exclusion model with open boundaries is solved exactly in one dimension. The exact solution is obtained by deriving a recursion relation for the steady state: if the steady state
Exact solution of a 1d asymmetric exclusion model using a matrix formulation
Several recent works have shown that the one-dimensional fully asymmetric exclusion model, which describes a system of particles hopping in a preferred direction with hard core interactions, can be

We consider a stochastic lattice gas with equal numbers of oppositely charged particles, diffusing under the influence of a uniform external electric field and the excluded-volume condition.

Steady states of driven lattice gases with open boundaries are investigated, and two types of phase transitions involving nonanalytic changes in the density profiles and the particles number fluctuation spectra are encountered upon varying the feeding rate and the particle interactions.
Exact solution of the totally asymmetric simple exclusion process: Shock profiles
The microscopic structure of macroscopic shocks in the one-dimensional, totally asymmetric simple exclusion process is obtained exactly from the complete solution of the stationary state of a model

The effect of a localized defect on the profile of a one-dimensional growing interface is considered. The (q, q') phase diagram of a restricted solid-on-solid growth model is studied within the mean
