The Non--Ergodicity Threshold: Time Scale for Magnetic Reversal
G. L. Celardo, J. Barre, F. Borgonovi +1
We prove the existence of a non-ergodicity threshold for an anisotropic classical Heisenberg model with all-to-all couplings. Below the threshold, the energy surface is disconnecte…

Birth and long-time stabilization of out-of-equilibrium coherent structures
Julien Barre, Freddy Bouchet, Thierry Dauxois +1
We study an analytically tractable model with long-range interactions for which an out-of-equilibrium very long-lived coherent structure spontaneously appears. The dynamics of this…

Inequivalence of ensembles in a system with long range interactions
Julien Barre', David Mukamel, Stefano Ruffo
We study the global phase diagram of the infinite range Blume-Emery-Griffiths model both in the canonical and in the microcanonical ensembles. The canonical phase diagram is known…
