Alternate islands of multiple isochronous chains in wave-particle interactions
Sousa, Meirielen Caetano de; Caldas, Ibere Luiz; Ozorio de Almeida, Alfredo Miguel; Rizzato, Felipe Barbedo; Pakter, Renato (2013) [Artículo de periódico]We analyze the dynamics of a relativistic particle moving in a uniform magnetic field and perturbed by a standing electrostatic wave. We show that a pulsed wave produces an infinite number of perturbative terms with the ... -
Multiple island chains in wave-particle interactions
Sousa, Meirielen Caetano de; Caldas, Ibere Luiz; Ozorio de Almeida, Alfredo Miguel; Pakter, Renato; Rizzato, Felipe Barbedo (2015) [Artículo de periódico]We analyze the isochronous island chains that appear in the Poincaré sections of near integrable twist systems. When the system presents just one resonant perturbation with a winding number, the number of chains is constant ...
