Gravitation in the Microcanonical Ensemble: Appropriate Scaling Leading to Extensivity and Thermalization
Maxime Champion, Angel Alastuey, Thierry Dauxois +1
We introduce a simple model of hard spheres with gravitational interactions, for which we study a suitable scaling limit. Usual extensive properties are maintained notwithstanding…
Kinetic theory of nonequilibrium stochastic long-range systems: Phase transition and bistability
Cesare Nardini, Shamik Gupta, Stefano Ruffo +2
We study long-range interacting systems driven by external stochastic forces that act collectively on all the particles constituting the system. Such a scenario is frequently encou…
Overdamped dynamics of long-range systems on a one-dimensional lattice: Dominance of the mean-field mode and phase transition
Shamik Gupta, Alessandro Campa, Stefano Ruffo
We consider the overdamped dynamics of a paradigmatic long-range system of particles residing on the sites of a one-dimensional lattice, in the presence of thermal noise. The inter…
One-dimensional lattice of oscillators coupled through power-law interactions: Continuum limit and dynamics of spatial Fourier modes
Shamik Gupta, Max Potters, Stefano Ruffo
We study synchronization in a system of phase-only oscillators residing on the sites of a one-dimensional periodic lattice. The oscillators interact with a strength that decays as…
