Bifurcations leading to stochasticity in a cyclotron-maser system
(1994) [Artigo de periódico]This paper is concerned with the orbital dynamics of electrons in a cyclotron maser [CO Chen, Phys. Rev. A 46,6654 (1992)] with modulated maser fields. Amplitude modulation is a natural result of wave-particle energy ... -
Improving regular acceleration in the nonlinear interaction of particles and waves
(1995) [Artigo de periódico]In this work one studies the effects arising from the inclusion of a stationary extraordinary mode in the resonant interaction of magnetized particles and perpendicularly propagating electrostatic waves. It is found that ... -
Manifold reconnection in chaotic regimes
(1998) [Artigo de periódico]In this paper we extend the concept of separatrix reconnection into chaotic regimes. We show that even under chaotic conditions one can still understand enhanced diffusion in phase space in terms of relatively smooth ... -
Particle acceleration by large-amplitude waves revisited
(1997) [Artigo de periódico]We reconsider the problem of particle acceleration by large-amplitude electromagnetic waves. We make use of a fully relativistic Hamiltonian formalism to show that, as opposed to nonelativistic results obtained by Kuo and ... -
Resonant islands without separatrix chaos
(1995) [Artigo de periódico]An alternative type of Hamiltonian nonlinear resonant island is analyzed. In the usual case where the resonant island is pendulumlike, chains bifurcated out of the central elliptic point undergo infinite cascades of ...
