Metastable States, Relaxation Times and Free-energy Barriers in Finite Dimensional Glassy Systems
arXiv:cond-mat/0507585 · doi:10.1209/epl/i2005-10420-8
Abstract
In this note we discuss metastability in a long-but-finite range disordered model for the glass transition. We show that relaxation is dominated by configuration belonging to metastable states and associate an in principle computable free-energy barrier to the equilibrium relaxation time. Adam-Gibbs like relaxation times appear naturally in this approach.
