The long-time behaviour of the wave-particle interaction is investigated through a Fermi-like model that describes the interaction as the results of a large number of collisions between an ensemble of particles and two infinitely massive bar- riers with variable amplitude. The results are compared with those of particle in cell (PIC) simulations. The system approaches statistical equilibrium through a phase space filamentation that is analogous to a laminar Gibbs process in a conservative system.

Abstract
The long-time behaviour of the wave-particle interaction is investigated through a Fermi-like model that describes the interaction as the results of a large number of collisions between an ensemble of particles and two infinitely massive bar- riers with variable amplitude. The results are compared with those of particle in cell (PIC) simulations. The system approaches statistical equilibrium through a phase space filamentation that is analogous to a laminar Gibbs process in a conservative system.File in questo prodotto:
