Random Energy Model

From Wikipedia, the free encyclopedia

In statistical physics of disordered systems the Random Energy Model is a toy model of a system with quenched disorder. It concerns the statistics of a system of N particles, such that the number of possible states for the systems grow as 2N, while the Energy of sush states is a gaussian stochastic variable. The model has exact solution. Its simpicity makes this model suitable for pedagogical introduction of concepts like quenched disorder and replica symmetry.
