Equilibrium and nonequilibrium properties of systems with long-range interactions
Stefano Ruffo
We briefly review some equilibrium and nonequilibrium properties of systems with long-range interactions. Such systems, which are characterized by a potential that weakly decays at…

Out-of-equilibrium tricritical point in a system with long-range interactions
Andrea Antoniazzi, Duccio Fanelli, Stefano Ruffo +1
Systems with long-range interactions display a short-time relaxation towards Quasi Stationary States (QSSs) whose lifetime increases with system size. With reference to the Hamilto…

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…
