The Hamiltonian Mean Field model: anomalous or normal diffusion?
Andrea Antoniazzi, Duccio Fanelli, Stefano Ruffo
We consider the out-of-equilibrium dynamics of the Hamiltonian Mean Field (HMF) model, by focusing in particular on the properties of single-particle diffusion. As we shall here de…
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…
Exploring the thermodynamic limit of Hamiltonian models: convergence to the Vlasov equation
Andrea Antoniazzi, Francesco Califano, Duccio Fanelli +1
We here discuss the emergence of Quasi Stationary States (QSS), a universal feature of systems with long-range interactions. With reference to the Hamiltonian Mean Field (HMF) mode…
Enhancement of particle trapping in the wave-particle interaction
Romain Bachelard, Andrea Antoniazzi, Cristel Chandre +2
The saturated dynamics of a Single-Pass Free Electron Laser is considered within a simplified mean-field approach. A method is proposed to increase the size of the macro-particle,…
Stabilizing the intensity of a wave amplified by a beam of particles
Romain Bachelard, Andrea Antoniazzi, Cristel Chandre +3
The intensity of an electromagnetic wave interacting self-consistently with a beam of charged particles as in a free electron laser, displays large oscillations due to an aggregate…
A maximum entropy principle explains quasi-stationary states in systems with long-range interactions: the example of the Hamiltonian Mean Field model
Andrea Antoniazzi, Duccio Fanelli, Julien Barré +3
A generic feature of systems with long-range interactions is the presence of {\it quasi-stationary} states with non-Gaussian single particle velocity distributions. For the case of…
