Statistical mechanics and dynamics of solvable models with long-range interactions
A. Campa, T. Dauxois, S. Ruffo
The two-body potential of systems with long-range interactions decays at large distances as , with , where is the space dimension. Examples are: gravit…
Abundance of regular orbits and out-of-equilibrium phase transitions in the thermodynamic limit for long-range systems
Romain Bachelard, Cristel Chandre, Duccio Fanelli +2
We investigate the dynamics of many-body long-range interacting systems, taking the Hamiltonian Mean Field model as a case study. We show that an abundance of regular trajectories,…
Negative magnetic susceptibility and nonequivalent ensembles for the mean-field spin model
A. Campa, S. Ruffo, H. Touchette
We calculate the thermodynamic entropy of the mean-field spin model in the microcanonical ensemble as a function of the energy and magnetization of the model. The entropy and…
Driven Macroscopic Quantum Tunneling of Ultracold Atoms in Engineered Optical Lattices
Ramaz Khomeriki, Stefano Ruffo, Sandro Wimberger
Coherent macroscopic tunneling of a Bose-Einstein condensate between two parts of an optical lattice separated by an energy barrier is theoretically investigated. We show that by a…
