Oriented graph structure of local energy minima in the random-field Ising model

摘要

In this paper we investigate the structure of the disordered energy landscape of the RFIM with field-driven single-spin-flip dynamics. We show that local energy minima are partitioned into equivalence classes (basins) organized in a binary oriented graph. We discuss two algorithms by which one can explore the oriented graph structure. (c) 2007 Elsevier B.V. All rights reserved.
