Abstract: We show that mixing for local, reversible dynamics of mean field spin glasses is exponentially slow in the low temperature regime. We introduce a notion of free energy barriers for the overlap, and prove that… read more here.

DOI: 10.1007/s10955-020-02684-z
Abstract: In this paper we study a multi-species disordered model on the Nishimori line. The typical properties of this line, a set of identities and inequalities among correlation functions, allow us to prove the replica symmetry… read more here.

Abstract: We study the zero-field optical spin noise (OSN) spectra for a thermal state dense 87Rb vapor. Our main findings are: (1) The OSN spectrum consists of two components representing a positive and a negative hyperfine… read more here.
