Phys. Rev. Lett. 96, 240602 (2006) [4 pages]Hamiltonian Dynamics Reveals the Existence of Quasistationary States for Long-Range Systems in Contact with a ReservoirReceived 10 March 2006; published 21 June 2006 We introduce a Hamiltonian dynamics for the description of long-range interacting systems in contact with a thermal bath (i.e., in the canonical ensemble). The dynamics confirms statistical mechanics equilibrium predictions for the Hamiltonian mean field model and the equilibrium ensemble equivalence. We find that long-lasting quasistationary states persist in the presence of the interaction with the environment. Our results indicate that quasistationary states are indeed reproducible in real physical experiments. © 2006 The American Physical Society URL:
