The construction relies on theintegrability of the models, a property that constrains the possible rates atthe boundaries. The realisation is built on a tensor product of copies of theDEHP algebras. Using this explicit construction, we are able to calculate thepartition function of the models. The densities and currents in the stationarystate are also computed. It leads to the phase diagram of the models. Dependingon the values of the boundary rates, we obtain for each species shock waves,maximal current, or low/high densities phases. |
