-dimensional spherical ferromagnets in random fields: Metastates, continuous symmetry breaking, and spin-glass features
Kalle Koskinen, Christof Külske
We study the large-volume behavior of the spherical model for -dimensional local spins, in the presence of -dimensional random fields, for . We compare two models, o…
