The convex structure of the Parisi formula for multi-species spin glasses
Hong-Bin Chen, Victor Issa, Jean-Christophe Mourrat
We study the free energy of mean-field multi-species spin glasses with convex covariance function. For such models with species, the Parisi formula is known to be valid, and ex…

On free energy of non-convex multi-species spin glasses
Hong-Bin Chen
In [arXiv:2311.08980], it was shown that if the limit of the free energy in a non-convex vector spin glass model exists, it must be a critical value of a certain functional. In thi…

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…
