In this paper we study a two-species driven diffusive system with open boundaries that exhibits spontaneous symmetry breaking in one dimension. In a symmetry broken state the currents of the two species are not equal, although the dynamics is symmetric. A mean-field theory predicts a sequence of two transitions from a strong symmetry broken state through an intermediate symmetry broken state to a symmetric state. However, a recent numerical study has questioned the existence of the intermediate… 
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
Symmetry breaking and ordering in driven diffusive systems
Driven diffusive systems provide a simple framework which captures some of the complex collective phenomena shown by non-equilibrium systems. Even in one dimension, they exhibit phase transitions,
The robustness of spontaneous symmetry breaking in a bridge model
A simple two-species asymmetric exclusion model in one dimension with bulk and boundary exchanges of particles is investigated for the existence of spontaneous symmetry breaking. The model is a

We study spontaneous symmetry breaking in a one-dimensional driven two-species stochastic cellular automaton with parallel sublattice update and open boundaries. The dynamics are symmetric with
Phase transitions in nonequilibrium stochastic particle systems with local conservation laws
Stochastic particle systems far from equilibrium show a great variety of critical phenomena already in one dimension. We concentrate on models where the number of particles is locally conserved. In

We introduce a class of 1D models mimicking a single-lane bridge with two junctions and two particle species driven in opposite directions. The model exhibits spontaneous symmetry breaking (SSB) for

It is argued that a U shock will occur whenever there are strong interactions between species such that the current-density relation develops a double well and the umbilical point becomes isolated, and it is proved that such an umbrella point is a general feature of multispecies driven diffusive systems with reflection symmetry of the bulk dynamics.
Persistence of spontaneous symmetry breaking in bidirectional transport system with reservoir crowding
Motivated by the impact of limited resources on the entry and exit of entities on a pathway in many transport systems, we investigate a system comprising of a bidirectional totally asymmetric simple

In addition to the known one-channel phases, two new regions are found, in particular one, where the total density is fixed, but the filling of the individual chains changes back and forth, with a preference for strongly different densities.
First-Order Phase Transitions in One-Dimensional Steady States
The steady states of the two-species (positive and negative particles) asymmetric exclusion model of Evans, Foster, Godrèche, and Mukamel are studied using Monte Carlo simulations. We show that
Minimal current phase and universal boundary layers in driven diffusive systems.
We investigate boundary-driven phase transitions in open driven diffusive systems. The generic phase diagram for systems with short-ranged interactions is governed by a simple extremal principle for
Steady-state selection in driven diffusive systems with open boundaries
We investigate the stationary states of one-dimensional driven diffusive systems, coupled to boundary reservoirs with fixed particle densities. We argue that the generic phase diagram is governed by
Phase diagram of one-dimensional driven lattice gases with open boundaries
We consider the asymmetric simple exclusion process (ASEP) with open boundaries and other driven stochastic lattice gases of particles entering, hopping and leaving a one- dimensional lattice. The

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 diffusion constant of a one-dimensional asymmetric exclusion model with open boundaries
For the 1D fully asymmetric exclusion model with open boundary conditions, we calculate exactly the fluctuations of the current of particles. The method used is an extension of a matrix technique
Asymmetric exclusion model with two species: Spontaneous symmetry breaking
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
