Escaping from cycles through a glass transition
Abstract
A random walk is performed over a disordered media composed of sites random and uniformly distributed inside a -dimensional hypercube. The walker cannot remain in the same site and hops to one of its neighboring sites with a transition probability that depends on the distance between sites according to a cost function . The stochasticity level is parametrized by a formal temperature . In the case , the walk is deterministic and ergodicity is broken: the phase space is divided in a number of attractor basins of two-cycles that trap the walker. For , analytic results indicate the existence of a glass transition at as . Below , the average trapping time in two-cycles diverges and out-of-equilibrium behavior appears. Similar glass transitions occur in higher dimensions choosing a proper cost function. We also present some results for the statistics of distances for Poisson spatial point processes.
