Mobile Atom Interferometric Sensors — •Kai Bongs1 and Mark A Kasevich2 — 1Institut für Laserphysik, Universität Hamburg, Jungiusstr. 9, 20355 Hamburg, Germany — 2Physics Department, Varian Building, Room 234, Stanford, California, 94305-4060, USA
We present the status of development of a mobile atom interferometric gravity gradient sensor which addresses many questions also connected to space instruments and thus paves the way for future developments. In addition we identify new classes of high-order phase shifts in a theoretical analysis, which are observable in current experiments, and which seem to be of vital importance for proposed future experiments.
During the last decade atom interferometric measurements have evolved from proof of principle experiments to precision sensors with possible applications in fundamental physics and commercial areas. These goals, however, hinge on the transfer of laboratory technology to field ready instruments as well as on the accuracy of the theory used to connect the measured interferometric phase shift to the physically relevant quantities.
The associated development of a small, modular and robust atom interferometric sensor for high precision earth gravity gradient mapping is discussed and new developments for the laser and vacuum system are presented.
In addition we develop analytic expressions for the response of commonly used atom interferometer measurement configurations to experimentally relevant combinations of rotation, gravity and gravity gradient-induced forces. K. Bongs acknowledges support from the DFG.
