We discuss interfaces in spin glasses. We present new theoretical results and a numerical method for characterizing overlap interfaces and the stability of the spin-glass phase in extended disordered systems. We use this definition to characterize the low temperature phase of hierarchical spin-glass models. We use the replica symmetry breaking theory to evaluate the cost for an overlap interface, which in these models is particularly simple.

Abstract
We discuss interfaces in spin glasses. We present new theoretical results and a numerical method for characterizing overlap interfaces and the stability of the spin-glass phase in extended disordered systems. We use this definition to characterize the low temperature phase of hierarchical spin-glass models. We use the replica symmetry breaking theory to evaluate the cost for an overlap interface, which in these models is particularly simple. A comparison of our results from numerical simulations with the theoretical predictions shows good agreement. © 2009 IOP Publishing Ltd.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
