Non-homogeneous mean field picture for spin-glasses
(Reçu le 14 octobre 1980, revise le 16 decembre, accepte le 22 decembre 1980) Résumé. 2014 Dans cette lettre, nous calculons la moyenne gelée (sans répliques) pour des verres de spin avec désordre local. Ceci permet une définition naturelle du champ moyen. On montre que les champs moyens décrivant les verres de spin sont du type instanton. Abstract. 2014 In this letter we perform quenched avera...
متن کاملMean field theory for Heisenberg spin glasses
2014 The infinite-ranged spin glass model is studied in the general case of m-component spins. Results for the magnetization laws, the shape of the phase diagram, the nature of the transitions are presented. J. Physique LETTRES 42 (1981) L-103 L-106 1 PI MARS 1981, Classification Physics Abstracts 05.50 75.50K The infinite-ranged model [1], introduced by D. Sherrington and S. Kirkpatrick (SK), ...
متن کاملMean field models for spin glasses
Translation from physics: ‘Glass’: a material which is hard and inflexible (like a solid) but is not completely ordered or lattice-like in its microscropic structure (thus, unlike a crystal or simple metals). ‘Spin’: pertaining to the magnetic spins of ions in a material. ‘Spin glass’: a material, effectively solid, which contains some irregular distribution of magnetizable ions. Basic laborato...
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 کاملOn 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 ...
