Abstract

We propose a design for an atomtronic rotation sensor consisting of an array of Bose– Einstein condensates (BECs) confined in a double–target–array potential. The purpose of the sensor is to measure the rotation speed, ΩR, of the sensor’s rest frame with respect to the “fixed stars.” The atomtronic system consists of an ultracold gas of sodium atoms compressed, using laser light, into a thin horizontal sheet and subjected to a double–target– array potential within the horizontal plane. A “target” BEC consists of 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–row and m–column array (n×m) of these double–target BECs. The measurement of ΩR is carried out by creating the array of double–target BECs (setup step), inducing 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). We describe a set of simulations showing that a 1×1 array behaves in a way that enables the correct operation of an n×m array for measuring ΩR. As a proof–of–concept of sensor operation we present an example simulation showing that a 2×2 array can be designed to measure ΩR in a user–specified range.
