Atom interferometry at arbitrary orientations and rotation rates

QA de Castanet, C Des Cognets… - Nature …, 2024 - pmc.ncbi.nlm.nih.gov
The exquisite precision of atom interferometers has sparked the interest of a large
community for uses ranging from fundamental physics to geodesy and inertial navigation.
However, their implementation for onboard applications is still limited, not least because
rotation and acceleration are intertwined in a single phase shift, which makes the extraction
of a useful signal more challenging. Moreover, the spatial separation of the wave packets
due to rotations leads to a loss of signal. We present an atom interferometer operating over a …
