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…
Density of states of continuous and discrete spin models: a case study
Cesare Nardini, Rachele Nerattini, Lapo Casetti
A relation between O(n) lattice spin models and Ising models defined on the same lattice was recently put forward [L. Casetti, C. Nardini, and R. Nerattini, Phys. Rev. Lett. 106, 0…
