On chaos in mean field spin glasses
We study the correlations between two equilibrium states of SK spin glasses at different temperatures or magnetic fields. The question, presiously investigated by Kondor and Kondor and Végsö, is approached here constraining two copies of the same system at different external parameters to have a fixed overlap. We find that imposing an overlap different from the minimal one implies an extensive ...
متن کاملAgainst Chaos in Temperature in Mean Field Spin Glass Models
We study the problem of chaos in temperature in some mean-field spin-glass models by means of a replica computation over a model of coupled systems. We propose a set of solutions of the saddle point equations which are intrinsically non-chaotic and solve a general problem regarding the consistency of their structure. These solutions are relevant in the case of uncoupled systems too, therefore t...
متن کاملNon-mean-field behavior of realistic spin glasses.
We provide rigorous proofs which show that the main features of the Parisi solution of the Sherrington-Kirkpatrick spin glass are not valid for more realistic spin glass models in any dimension and at any temperature. The theoretical perspective provided by the Parisi solution [17] of the infinite-ranged Sherrington-Kirkpatrick (SK) model [21] has dominated the spin glass literature over the pa...
متن کاملLow Temperature Asymptotics in Spherical Mean Field Spin Glasses
In this paper, we study the low temperature limit of the spherical Crisanti-Sommers variational problem. We identify the Γ-limit of the Crisanti-Sommers functionals, thereby establishing a rigorous variational problem for the ground state energy of spherical mixed p-spin glasses. As an application, we compute moderate deviations of the corresponding minimizers in the low temperature limit. In p...
متن کاملMean - field theory of temperature cycling experiments in spin - glasses
We study analytically the effect of temperature cyclings in mean-field spinglasses. In accordance with real experiments, we obtain a strong reinitialization of the dynamics on decreasing the temperature combined with memory effects when the original high temperature is restored. The same calculation applied to meanfield models of structural glasses shows no such reinitialization, again in accor...
