For general cases where particles have an extended size and hop at site-dependent rates, however, theoretically analyzing the dynamics has remained elusive. Here, we present such an analysis by deriving and solving the hydrodynamic limit. We obtain closed-form formulas for steady-state particle densities and currents, as well as phase transition boundaries. Surprisingly the latter depend on only four parameters: the particle size and the first, the last, and the minimum hopping rates. Our results agree well with Monte Carlo simulations and can be used in inference.", "revisions": [ { "version": "v1", "updated": "2018-03-15T06:08:28.000Z" } ], "analyses": { "keywords": [ "hydrodynamic limit", "open boundaries", "totally asymmetric simple exclusion process", "derivation", "phase transition boundaries" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
