LATIN - Lattice Atom Interferometry

New frontiers in quantum sensing with ultra-long interaction times

Atom interferometers have enabled us to measure forces with exceptionally high precision. Inevitably, these forces are averaged over the free-fall trajectory of the atoms (up to 10 m), since sensitivity scales with the free-fall time. This precludes measurements of localized forces. To shrink these distances we will use the optical lattice of a high finesse cavity to hold the atoms against gravity in order to perform lattice atom interferometry with ultra long interaction times.
