Multidimensional Atom Optics and Interferometry

Quantum and Atom Optics

Prospects for atom interferometry

Atom interferometers were ® rst realized ten years ago, and since then have evolved from beautiful demonstrations of quantum physics into instruments at the leading edge of precision measurement. In this article we trace the development of atom interferometry, looking at how the physical principles have been put into practice to achieve ground-breaking experiments. We also discuss new atom opti...

Light-pulse atom interferometry

— The light-pulse atom interferometry method is reviewed. Applications of the method to inertial navigation and tests of the Equivalence Principle are discussed.

Single Atom and Two Atom Ramsey Interferometry with Quantized Fields

Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case it is shown how an analog of Hanbury-Brown Twiss photon-photon correlation interferometry can be used to discern a variety of interferenc...

Testing Atom and Neutron Neutrality with Atom Interferometry

Introduction. Charge quantization and atom neutrality in the Standard Model (SM) are mysteries which are automatically solved when the theory is embedded in a Grand Unified group. Even then, Witten has shown [1] that in the presence of CP non-conservation magnetic monopoles acquire an electric charge that is proportional to the amount of CP violation, a non-quantized quantity. This suggests tha...
