Multi-axis inertial sensing with 2D matter-wave arrays

Atom interferometry is an exquisite measurement technique sensitive to inertial forces. However, it is commonly limited to a single sensitive axis, allowing high-precision multi-dimensional sensing only through subsequent or post-corrected measurements. Knut Stolzenberg and Daida Thomas and their team have now presented a novel method for multi-axis inertial sensing based on the correlation of…
