Control and Tracking of Unstable Orbits in Hamiltonian Flows: The Diamagnetic Kepler Problem
We report on the application of chaos control to the irregular motion of an electron under the combined influence of a Coulomb and a magnetic field, the so-called ``diamagnetic Kepler problem'' (DKP). We show how to stabilize the classical chaotic orbits into regular motion and present a new method to follow the unstable orbits as the energy is increased from the regular to the chaotic regime.
