Realization of novel atomic vector accelerometers based on atoms confined in a multidimensional optical lattice

We report two innovative multidimensional atomic interferometers capable of sensing both the magnitude and direction of applied inertial forces. Through the modulation of a two-dimensional optical lattice position, we realize simultaneous Bloch oscillations in two dimensions, and a two-dimensional Michelson interferometer. We highlight experimental improvements from a one-dimensional lattice system which have enabled vector measurements. Bayesian reconstruction of many experimental runs is also analyzed and presented to ascertain the performance of these new class of multidimensional atomic interferometers. The progression toward increased sensitivity and possible field-deployable applications is also discussed.
