Collective excitation interferometry with a toroidal Bose-Einstein condensate
Collective excitation interferometry with a toroidal Bose-Einstein condensate
The precision of most compact inertial sensing schemes using trapped- and guided-atom interferometers has been limited by uncontrolled phase errors caused by trapping potentials and interactions. Here we propose an acoustic interferometer that uses sound waves in a toroidal Bose-Einstein condensate to measure rotation, and we demonstrate experimentally several key …
