Static and dynamic glass-glass transitions: a mean-field study
Résumé
A family of mean-field glass models is studied by means of a Langevin-based approach to the dynamics and a Replica theory computation of the thermodynamics. The phase diagram of a particular model case is shown, where glass-to-glass transitions occur between phases with a different number of characteristic time-scales for the relaxation processes. The appearence of Johari-Goldstein processes as collective reorganizations of sets of fast processes is discussed.
