Mercè Ollé (UPC, Barcelona):Dynamical systems tools to study a hydrogen atom

We consider the problem of the hydrogen atom interacting with a circularly polarized microwave field, modelled by a perturbed Kepler problem. In this talk, we concentrate mainly in three parts: the first one concerning the general features of the CP problem, the second one is related to the description of the dynamics from a global point of view (taking into account the main invariant objects), and finally we study the ionizing orbits, that is orbits that escape to infinity.
