Distribution of current in non-equilibrium diffusive systems and phase transitions | | T. Bodineau

21 Jun 2005 | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Abstract: | We consider diffusive lattice gases on a ring and analyze the stability of their density profiles conditionally to a current deviation. Depending on the current, one observes a phase transition between a regime where the density remains constant and another regime where the density becomes time dependent. Numerical data confirm this phase transition. This time dependent profile persists in the large drift limit and allows one to understand on physical grounds the results obtained earlier for the totally asymmetric exclusion process on a ring. | | Source: | arXiv, cond-mat/0506540 | | Services: | Forum | Review | PDF | Favorites | |
