Jamming percolation and glass transitions in lattice models | | Cristina Toninelli

27 Jan 2006 | | Journal: | Phys Rev Lett, 96 (3), 035702 | | Abstract: | A new class of lattice gas models with trivial interactions but constrained dynamics is introduced. These models are proven to exhibit a dynamical glass transition: above a critical density rhoc ergodicity is broken due to the appearance of an infinite spanning cluster of jammed particles. The fraction of jammed particles is discontinuous at the transition, while in the unjammed phase dynamical correlation lengths and time scales diverge as exp[C(rhoc-rho)-mu]. Dynamic correlations display two-step relaxation similar to glass formers and jamming systems. | | Source: | PubMed, pmid16486732 | | Other source: | [GID 1065121] cond-mat/0509661 | | Services: | Forum | Review | Favorites | |
