Brief Description:
Special Note:

Abstract: Bipartite spin glasses -- a variant of usual spin glasses, in which spins are grouped into two species -- are a classical testing ground for new approaches in spin glass theory. The annealed complexity of bipartite spherical models was initially considered by Auffinger and Chen, who gave upper and lower bounds. We give an exact variational formula for this complexity, both for pure spin glasses and for mixtures. We also find connections between this model and the usual spherical spin glasses, in the sense of their complexity as studied by Auffinger, Ben Arous, and Černý.
