Chaos and Interaction of Atoms with Self-Consistent Fields in the Case of Small Coupling Constants
Dima L. Shepelyansky
Abstract
The interaction of three-level atoms with a two-mode classical electromagnetic field is considered in the case when transitions between all levels are allowed. It is found that for exact resonance with field frequencies the dynamics is chaotic in the rotating-wave approximation, i.e., for an arbitrarily small atomic density. The possibility of experimental observation of this phenomenon for Rydberg atoms is discussed.
