We investigate the dynamics of the asymmetric exclusion process at a junction. When two input roads are initially fully occupied and a single output road is initially empty, the ensuing rarefaction wave has a rich spatial structure. The density profile also changes dramatically as the initial densities are varied. Related phenomenology arises when one road feeds into two. Finally, we determine the phase diagram of the open system, where particles are fed into two roads at rate α for each road…

Continuous and discontinuous waves in an ASEP with pockets
We consider a geometric modification of the asymmetric simple exclusion process model in which each site of a one-dimensional chain is attached to a lateral dead-end site. Since it has an


Asymmetric exclusion process with global hopping.
It is shown that in addition to the discontinuity in the vicinity of the special site, a shock wave is formed in the bulk of the system when the density exceeds the critical density.
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.

A system composed of two parallel totally asymmetric simple exclusion processes with open boundaries, where the particles move in the two lanes in opposite directions and are allowed to jump to the other lane with rates inversely proportional to the length of the system, undergoes a discontinuous phase transition.
Abstract A number of exact results have been obtained recently for the one-dimensional asymmetric simple exclusion process, a model of particles which hop to their right at random times, on a
Role of network junctions for the totally asymmetric simple exclusion process.
Several mechanisms of the totally asymmetric simple exclusion process on a multiloop structure in which several segments share a single junction are illustrated, including phase diagrams in terms of the control parameters.
The Asymmetric Exclusion Process Revisited: Fluctuations and Dynamics in the Domain Wall Picture
We investigate the total asymmetric exclusion process by analyzing the dynamics of the shock. Within this approach we are able to calculate the fluctuations of the number of particles and density
Phase diagrams of two-lane driven diffusive systems
We consider a large class of two-lane driven diffusive systems in contact with reservoirs at their boundaries and develop a stability analysis of mean-field profiles as a method to derive the phase
Shock formation and traffic jam induced by a crossing in the 1D asymmetric exclusion model
The asymmetric simple-exclusion model on two-crossing one-dimensional lattices is considered for studying shock formation and traffic jams induced by a crossing. The condition for shock formation is
Phase separation in disordered exclusion models
The effect of quenched disorder in the one-dimensional asymmetric exclusion process is reviewed. Both particlewise and sitewise disorder generically induce phase separation in a range of densities.
