Interferometry with Bose-Einstein Condensates for inertial sensing — •Sven Abend1, Christian Schubert2, Matthias Gersemann1, Ernst M. Rasel1, and QUANTUS-QGYRO Teams1 — 1Institut für Quantenoptik, LU Hannover — 2DLR-SI, Hannover
Matter-wave interferometers show great a potential for improving inertial sensing. The absence of drifts recommends them for a variety of applications in geodesy, navigation, or fundamental physics. Bose-Einstein condensates (BECs) provide the means to achieve the lowest expansion energies of few picokelvin.
Such ensembles, bring in reach extremely accurate gravimeters, accelerometers and gyroscopes. An atom interferometer with scalable area may be formed in a twin lattice combined with a relaunch mechanism to obtain multi loops as well. Due to this scalability, it offers the perspective of reaching unprecedented sensitivities for rotations in comparably compact sensor head setups.
Moreover, atom-chip technologies offer the possibility to generate a BEC, paving the way for field-deployable miniaturized atomic devices. The extremely low expansion energies of BECs open up to extend the time atoms spend in the interferometer to tens of seconds. This brings in reach unprecedented sensitivities in space-borne applications.
