Abstract:The microwave ionization of internally chaotic Rydberg atoms is studied analytically and numerically. The internal chaos is induced by magnetic or static electric fields. This leads to a chaotic enhancement of microwave excitation. The dynamical localization theory gives a detailed description of the excitation process even in a regime where up to few thousands photons are required to ionize one atom. Possible laboratory experiments are also discussed.
