Hydrodynamic limit of multichain driven diffusive models.
A class of models, generalizing asymmetric exclusion process for many parallel interacting channels, is proposed. We couple the models with boundary reservoirs, study boundary-driven phase transitions, and show that usually taken hydrodynamic description fails. The adequate hydrodynamic limit is then derived. We support our findings with Monte Carlo simulations of the original stochastic system.
