TITLE: Two-Atom Interferometer
ABSTRACT: The two-atom interferometer introduces two different yet indistinguishable alternatives for randomly paired atoms to create a joint atom-detection event. The superposition of two-atom amplitudes yields two-atom interference with peculiar features which outshine the classic atom interferometer: (1) two-atom interference is still observable when the time delay of the interferometer is greater than the coherence time of the atom field and (2) two-atom interference may eliminate phase noises, including background, variation, turbulence and Raman laser induced phase noises; thereby allowing for higher sensitivity and stability sensing than is achievable by classic atom interferometers. These features are crucial in high sensitivity-accuracy acceleration and rotation measurements.
Proposal will be held using Webex.
