| Summary: | Stochastic motion of relativistic electrons under conditions of the nonlinear
resonance interaction of particles with space plasma waves is studied.
Particular attention is given to the problem of the stability and variability
of the Earth's radiation belts. It is found that the interaction between
whistler-mode waves and radiation-belt electrons is likely to involve the
same mechanism that is responsible for the dynamical balance between the
accelerating process and relativistic electron precipitation events. We have
also considered the efficiency of the mechanism of stochastic surfing
acceleration of cosmic electrons at the supernova remnant shock front, and
the accelerating process driven by a Langmuir wave packet in producing cosmic
ray electrons. The dynamics of cosmic electrons is formulated in terms of a
dissipative map involving the effect of synchrotron emission. We present
analytical and numerical methods for studying Hamiltonian chaos and
dissipative strange attractors, and for determining the heating extent and
energy spectra. |
