  We discuss the effects of particle exchange through open boundaries and the
induced drive on the phase structure and condensation phenomena of a stochastic
transport process with tunable short-range interactions featuring
pair-factorized steady states (PFSS) in the closed system. In this model, the
steady state of the particle hopping process can be tuned to yield properties
from the zero-range process (ZRP) condensation model to those of models with
spa- tially extended condensates. By varying the particle exchange rates as
well as the presence of a global drift, we observe a phase transition from a
free particle gas to a phase with condensates aggregated to the boundaries.
While this transition is similar to previous results for the ZRP, we find that
the mechanism is different as the presence of the boundary actually influences
the interaction due to the non-zero interaction range.
