Free energy of non-convex multi-species spin glasses with centered Ising spins

Hong-Bin Chen, Victor Issa, Jean-Christophe Mourrat

We identify the limit free energy of all multi-species spin glasses with centered spins. The result was previously known only under a convexity assumption on the covariance…

Vector spin glasses with Mattis interaction II: non-convex high-temperature models

Hong-Bin Chen, Victor Issa

This paper constitutes the second part of a two-paper series devoted to the systematic study of vector spin glass models whose energy function involves a spin glass part and a gene…

Vector spin glasses with Mattis interaction I: the convex case

Hong-Bin Chen, Victor Issa

This paper constitutes the first part of a two-paper series devoted to the systematic study of vector spin glass models whose energy function involves a spin glass part and a gener…

One-sided large deviations for the ground-state energy of spin glasses

Hong-Bin Chen, Alice Guionnet, Justin Ko +2

We describe the large deviations above its typical value of the maximal energy of a spin glass with +/-1 spins. Thanks to the relatively explicit description of the rate function w…

On the free energy of vector spin glasses with non-convex interactions

Hong-Bin Chen, Jean-Christophe Mourrat

The limit free energy of spin-glass models with convex interactions can be represented as a variational problem involving an explicit functional. Models with non-convex interaction…

Simultaneous replica-symmetry breaking for vector spin glasses

Hong-Bin Chen, Jean-Christophe Mourrat

We consider mean-field vector spin glasses with possibly non-convex interactions. Up to a small perturbation of the parameters defining the model, the asymptotic behavior of the Gi…
