Open Boundary Conditions in Stochastic Transport Processes with Pair-factorized Steady States

Using numerical methods we discuss the effects of open boundary conditions on condensation phenomena in the zero-range pro- cess (ZRP) and transport processes with pair-factorized steady states (PFSS), an extended model of the ZRP with nearest-neighbor interaction. For the zero-range process we compare to analytical results in the literature with respect to criticality and condensa- tion. For the extended model we find a similar phase structure, but observe supercritical phases with droplet formation for strong boundary drives.
