Anomalous transport of magnetized electrons interacting with EC waves

摘要: We consider the nonlinear interaction of magnetized electrons with an oblique narrow-band electromagnetic wave-packet. The is analysed over and near local threshold to chaos. statistical character forcing that controls trajectories particles also studied. focus our analysis on issues related energy spatial diffusion across magnetic field by following evolution ensemble mean squares (γ − γ0)2 (r⊥−r⊥0)2 for various values wave amplitude angle propagation. study, in particular, waves having strong moderate amplitudes, transition chaos, where dynamics complex a mixture periodic stochastic orbits coexist. electron diffusions real spaces are found obey simple power laws time, scaling exponents indicative sub-diffusion. This direct consequence effect resonant phase-space islands particle motion.
