Phys. Rev. A 67, 033601 (2003) [8 pages]Atomic-phase interference devices based on ring-shaped Bose-Einstein condensates: Two-ring caseReceived 12 September 2002; published 11 March 2003 We theoretically investigate the ground-state properties and quantum dynamics of a pair of adjacent ring-shaped Bose-Einstein condensates that are coupled via tunneling. This device, which is the analog of a symmetric superconducting quantum interference device, is the simplest version of what we term an atomic-phase interference device (APHID). The two-ring APHID is shown to be sensitive to rotation. © 2003 The American Physical Society URL:
