Abstract

Adiabatic invariant Charged particle acceleration and transport Nonlinear waves Probability of trapping Wave-particle resonant interaction
•We reviewed the resonant wave-particle interaction in various Sapace Plasma systems.•We presented a general theory of trapping (capture) into resoance and scattering on resonance of charged particles by electrostatic or electromagnetic waves in the presence of a background magnetic field. In the present review we survey space plasma systems where the nonlinear resonant interaction between charged particles and electromagnetic waves plays an important role. We focus on particle acceleration by strong electromagnetic waves. We start with presenting a general description of nonlinear resonant interaction based on the theory of slow-fast Hamiltonian systems with resonances. Then we turn to several manifestations of the resonance effects in various space plasma systems. We describe a universal approach for evaluating main characteristics of the resonant particle dynamics: probability of trapping into resonance, energy change due to scattering and trapping. Then we demonstrate how effects of nonlinear resonant trapping and scattering can be combined in a generalized kinetic equation. We also discuss the stability of trapped motion and evolution of particle ensemble in systems with trapping. The main objective of this review is to provide a general approach for characterizing plasma systems with nonlinear resonant interactions.
