note = {In this work the influence of bulk reservoirs on lattice models for many-particle systems far from equilibrium is studied.
A hydrodynamic equation is presented that allows to compute the steady state density profile for single species driven diffusive systems with open boundaries and a coupling of the bulk reservoir scaling with the inverse system size. Furthermore, a related model for a limit order market as well as the case of periodic single species driven models with a weak coupling to the reservoir are treated.
New results on driven systems with two particle species are presented both for the cases with and without coupling to a bulk reservoir. For a two species model with periodic boundaries and conserving dynamics a novel type of phase transition is observed that is formally similar to Bose-Einstein condensation.
In absence of a bulk reservoir, the existence of a spontaneously symmetry broken phase in a two species model with open boundaries and deterministic bulk behavior is demonstrated by regarding the dynamics of the system. For a related model with non-conserving bulk dynamics a rich phase diagram is found.
In systems with an absorbing phase transition the action of the reservoir is that of an external field. For the universality class of directed percolation the scaling functions are determined in several dimensions.},
