Phase transitions of quasistationary states in the Hamiltonian Mean Field model
Pierre de Buyl, Duccio Fanelli, Stefano Ruffo
The out-of-equilibrium dynamics of the Hamiltonian Mean Field (HMF) model is studied in presence of an externally imposed magnetic field h. Lynden-Bell's theory of violent relaxati…
Linear response theory for long-range interacting systems in quasistationary states
Aurelio Patelli, Shamik Gupta, Cesare Nardini +1
Long-range interacting systems, while relaxing to equilibrium, often get trapped in long-lived quasistationary states which have lifetimes that diverge with the system size. In thi…
Kinetic theory for non-equilibrium stationary states in long-range interacting systems
Cesare Nardini, Shamik Gupta, Stefano Ruffo +2
We study long-range interacting systems perturbed by external stochastic forces. Unlike the case of short-range systems, where stochastic forces usually act locally on each particl…
