Stable Quantum Resonances in Atom Optics

Doppleron-catalyzed Bragg resonances in atom optics.

A novel scheme to achieve large-angle atomic diffraction by standing-wave fields is proposed. It uses a highorder Doppleron resonance as a catalyst to speed up a high-order Bragg resonance by orders of magnitude. This effect occurs when the atom-field frequency detuning is such that the Bragg resonance and the Doppleron resonance become degenerate.

Classical and Quantum Chaos in Atom Optics

The interaction of an atom with an electromagnetic field is discussed in the presence of a time periodic external modulating force. It is explained that a control on atom by electromagnetic fields helps to design the quantum analog of classical optical systems. In these atom optical systems chaos may appear at the onset of external fields. The classical and quantum chaotic dynamics is discussed...

Quantum State Reconstruction Using Atom Optics

The development of methods for completely determining the quantum state of an atom or cavity field @1# continues to be an important issue in atomic physics. For example, in the field of quantum optics, schemes have been recently proposed, based on the Stem-Gerlach effect, for completely determining the quantum state of an atom as a way of fully characterizing the quantized electromagnetic field...
