Abstract
The free energy of multiple systems of spherical spin glasses with constrained overlaps was first studied in arXiv:math/0604082. The authors proved an upper bound of the constrained free energy using Guerra's interpolation. In this paper, we prove this upper bound is sharp. Our approach combines the ideas of the Aizenman-Sims-Starr scheme in arXiv:1204.5115 and the synchronization mechanism used in the vector spin models in arXiv:1512.04441 and arXiv:1512.00370 to prove the matching lower bound. We derive a vector version of the Aizenman-Sims-Starr scheme for spherical spin glass and use the synchronization property of arrays obeying the overlap-matrix form of the Ghirlanda-Guerra identities to prove the matching lower bound.
