Two-Atom Interferometer
Abstract
The concept of two-atom interferometer is adapted from the two-photon interferometer. Recent research at UMBC has demonstrated two peculiar features of two-photon interferometer. These features are useful for atom interferometers, especially for the Navy atom gyroscope. The coherence and stability problems have been the major barriers limiting the development of classic atom interferometers. This research will investigate the feasibility of turbulence-free two-atom interferometer and the general theory of second-order atomic coherence. The proposed theoretical investigations shall conclude a second-order correlation measurement protocol that is able to measure the atom-number fluctuation correlation, namely the quantum noise correlation, from the output atom beams of the proposed two-atom interferometer. The results of this research will better inform correlation measurement - circuitry preparation, such that the Navy could design a successful two-atom gyroscope. The mechanism of two-atom interference is relevant to the Navy in that it will be applied to the Navy atom-gyroscope to enhance navigation precision.
