A static interpretation of the order-parameters in spin-glasses

Abstract
The spin-glass phase is described as a statistical mixture of an infinite number of phases. The order-parameters q(x) and Δ(x ), with x ∈ [0, 1] measure the correlation between the phases, and the linear response anomaly respectively. Sompolinsky's solution is recovered and reinterpreted.
Résumé
La phase verre de spin est décrite comme un mélange statistique d'un nombre infini de phases. Les paramètres d'ordre q(x) et Δ(x), avec x ∈ [0, 1], mesurent respectivement les corrélations entre ces phases et l'anomalie de réponse linéaire. La solution de Sompolinsky est ainsi obtenue, et rediscutée.
