Some recent results and perspectives in statistical mechanics

Giovanni JONA-LASINIO, Dipartimento di Fisica, Università di Roma "La Sapienza", Roma, Italy

In the last two decades non trivial progress has been made in understanding nonequilibrium phenomena studying simplified statistical mechanical models, the lattice gases, in the so called scaling limit. This has led to a number of new predictions: the existence of phase transitions not permitted in equilibrium, dynamical phase transitions spontaneously breaking time translation invariance in current fluctuations and universal scaling properties of their moments, a Clausius type inequality for nonequilibrium stationary states, symmetry breaking and symmetry restoring in nonequilibrium....
