We look at recent important improvements in the comprehension of the properties of mean-field magnetic models with built-in quenched disorder, qualitatively well describing both the spin-glass and the glass phase. Connecting apparently different approaches, we present our results on a particular model displaying both a glass and a spin-glass phase in different regions of the thermodynamic parameters space, focusing on the complexity function counting the number of relevant stable and metastable states.

Abstract
We look at recent important improvements in the comprehension of the properties of mean-field magnetic models with built-in quenched disorder, qualitatively well describing both the spin-glass and the glass phase. Connecting apparently different approaches, we present our results on a particular model displaying both a glass and a spin-glass phase in different regions of the thermodynamic parameters space, focusing on the complexity function counting the number of relevant stable and metastable states.File in questo prodotto:
