Double-target atomtronic rotation sensor
Prof. Dr. Mark Edwards, Fuller E. Callaway Professor of Physics, Georgia Southern University, Statesboro, GA, U.S.A.
We present a proof-of-concept design for an atomtronic rotation sensor array consisting of a ``double-target'' Bose-Einstein condensates (BECs). A “target” BEC is a disk-shaped condensate surrounded by a concentric ring-shaped condensate. A “double-target” BEC is two adjacent target BECs whose ring condensates partially overlap. The sensor consists of an n x m array of these double-target BECs. The measurement of the frame rotation speed,Omega_{R}, is carried out by creating an array of double-target BECs (setup step), inducing one unit of quantized flow in the top ring of each member of the array (initialization step), applying potential barriers in the overlap region of each member (measurement step), and observing whether the induced flow is transferred from the top to the bottom ring in each member (readout step).
