Isochronous island bifurcations driven by resonant magnetic perturbations in Tokamaks
B. B. Leal, I. L. Caldas, M. C. de Sousa +2
Recent evidences show that heteroclinic bifurcations in magnetic islands may be caused by the amplitude variation of resonant magnetic perturbations in tokamaks. To investigate the…
Internal energy exchanges and chaotic dynamics in an intrinsically coupled system
M. C. de Sousa, A. B. Schelin, F. A. Marcus +2
Intrinsically coupled nonlinear systems present different oscillating components that exchange energy among themselves. A paradigmatic example is the spring pendulum, which display…
Improving particle beam acceleration in plasmas
M. C. de Sousa, I. L. Caldas
The dynamics of wave-particle interactions in magnetized plasmas restricts the wave amplitude to moderate values for particle beam acceleration from rest energy. We analyze how a p…
Energy Distribution in Intrinsically Coupled Systems: The Spring Pendulum Paradigm
M. C. de Sousa, F. A. Marcus, I. L. Caldas +1
Intrinsically nonlinear coupled systems present different oscillating components that exchange energy among themselves. We present a new approach to deal with such energy exchanges…
