Spontaneous Symmetry Breaking in a Non-Conserving Two-Species Driven Model | | E. Levine

10 Nov 2003 | | Journal: | J. Phys. A : Math. Gen. 37, 3333 (2004). | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Abstract: | A two species particle model on an open chain with dynamics which is non-conserving in the bulk is introduced. The dynamical rules which define the model obey a symmetry between the two species. The model exhibits a rich behavior which includes spontaneous symmetry breaking and localized shocks. The phase diagram in several regions of parameter space is calculated within mean-field approximation, and compared with Monte-Carlo simulations. In the limit where fluctuations in the number of particles in the system are taken to zero, an exact solution is obtained. We present and analyze a physical picture which serves to explain the different phases of the model. | | Source: | arXiv, cond-mat/0311218 | | Services: | Forum | Review | PDF | Favorites | |
