Abstract

A theoretical investigation of a pair of ring Bose-Einstein condensates (BECs) coupled by tunneling as the simplest example of a potential atomic-phase interference device (APHID) is presented. It is shown that the two-ring APHID has interesting ground-state properties, with density profiles reminiscent of dark soliton states around the point of contact of the rings. Furthermore, it is demonstrated that Josephson oscillations between the two rings can occur, and that these oscillations are sensitive to the state of rotation of the APHID.
