In this study we consider the Hamiltonian approach for the construction of a map for a system with nonlinear resonant interaction, including phase trapping and phase bunching effects. We derive basic equations for a single resonant trajectory analysis and then generalize them into a map in the energy/pitch-angle space. The main advances of this approach are the possibility of considering effects of many resonances and to simulate the evolution of the resonant particle ensemble on long time…

Probabilistic approach to nonlinear wave-particle resonant interaction.

It is demonstrated that individual particle motion can be characterized by the probability of trapping into the resonance with the wave and by the efficiency of scattering at resonance, which can be used to construct a kinetic equation (or generalized Fokker-Planck equation) modeling the long-term evolution of the particle distribution.
