Mean-field model for the density of states of jammed soft spheres
Fernanda P. C. Benetti, Giorgio Parisi, Francesca Pietracaprina +1
We propose a class of mean-field models for the isostatic transition of systems of soft spheres, in which the contact network is modeled as a random graph and each contact is assoc…
Collisional relaxation in the inhomogeneous Hamiltonian-Mean-Field model: diffusion coefficients
Fernanda P. C. Benetti, Bruno Marcos
Systems of particles with long range interactions present two important processes: first, the formation of out-of-equilibrium quasi-stationary states (QSS), and the collisional rel…
Ensemble inequivalence in a mean-field XY model with ferromagnetic and nematic couplings
Arkady Pikovsky, Shamik Gupta, Tarcisio N. Teles +4
We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spins with ferromagnetic and nematic coupling. We demonstrate the inequival…
Nonequilibrium stationary states of 3D self-gravitating systems
Fernanda P. C. Benetti, Ana C. Ribeiro-Teixeira, Renato Pakter +1
Three dimensional self-gravitating systems do not evolve to thermodynamic equilibrium, but become trapped in nonequilibrium quasistationary states. In this Letter we present a theo…
