چکیده

We consider a finite-range spin glass model in arbitrary dimension, where the strength of the two-body coupling decays to zero over some distance gamma(-1). We show that, under mild assumptions on the interaction potential, the infinite-volume free energy of the system converges to that of the Sherrington-Kirkpatrick one, in the Kac limit gamma-->0. This could be a first step toward an expansion around mean-field theory, for spin glass systems.

Finite-range spin glasses in the Kac limit: free energy and local observables

We study a finite-range spin-glass model in arbitrary dimension, where the intensity of the coupling between spins decays to zero over some distance γ−1. We prove that, under a positivity condition for the interaction potential, the infinite-volume free energy of the system converges to that of the Sherrington– Kirkpatrick model, in the Kac limit γ → 0. We study the implication of this converge...

Spin glass models with Kac interactions

In this paper I will review my work on disordered systems -spin glass model with two body and p > 2 body interactionswith long but finite interaction range R. I will describe the relation of these model with Mean Field Theory in the Kac limit and some attempts to go beyond mean field. PACS. 0 5.20.-y,75.10Nr

On the dynamics of Kac p-spin glasses

This paper discusses the dynamical properties of p-spin models with Kac kind interactions. For large but finite interaction range R one finds two different time scales for relaxation. A first relaxation roughly independent of R where the system is confined to limited regions of the configuration space and an R dependent time scale where the system is able to escape the confining regions. I will...

A field-theoretical approach to the spin glass transition: models with long but finite interaction range

We study spin glasses with the Kac-type interaction potential for small but finite inverse interaction range γ. Using the theoretical set-up of coupled replicas, through the replica method we argue that the probability of overlap profiles can be expressed for small γ through a large deviation functional. This result is supported by rigorous arguments, showing that the large deviation functional...

Mean-field theory of spin-glasses with finite coordination number.

The mean-field theory of dilute spin-glasses is studied in the limit where the average coordination number is finite. The zero-temperature phase diagram is calculated and the relationship between the spin-glass phase and the percolation transition is discussed. The present formalism is applicable also to graph optimization problems. The mean-field theory (MFT) of spin-glasses usually refers to ...
