Programmable Bloch-Band Atom Interferometry in a Multidimensional Optical Lattice

Atom interferometers are exquisite sensors that have been used to perform inertial measurements with ever increasing precision. However, many worthy scientific endeavors present dynamically harsh environments and strict SWaP requirements that are challenging to accommodate for conventional atom interferometers. In this defense, I present the novel approach of Bloch-band interferometry, which confines Bose-condensed atoms to a multidimensional optical lattice for the entire interferometer sequence. This sensor, paired with machine learning, realizes a compact, reconfigurable device capable of performing as an accelerometer, gyroscope, or gravity gradiometer in multiple dimensions. Proof-of-principle experiments and a pathway to state-of-the-art performance are presented.
