@article{Artemyev2021LongtermDD, title={Long-term dynamics driven by resonant wave–particle interactions: from Hamiltonian resonance theory to phase space mapping}, author={Anton V. Artemyev and Anatoly I. Neishtadt and Alexei Vasiliev and Xiao‐jia Zhang and Didier Mourenas and Dmitri L. Vainchtein}, journal={Journal of Plasma Physics}, year={2021}, volume={87} }

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…
