Phys. Rev. A 66, 023604 (2002) [8 pages]Theory of a one-dimensional double-X-junction atom interferometerReceived 11 March 2002; published 12 August 2002 The dynamics of an atom waveguide X-junction beam splitter becomes truly one dimensional in a regime of low temperatures and densities and large positive scattering lengths where the transverse mode becomes frozen and the many-body Schrödinger dynamics becomes exactly soluble via a generalized Fermi-Bose mapping theorem. We analyze the interferometric response of a double-X-junction interferometer of this type due to potential differences between the interferometer arms. © 2002 The American Physical Society URL:
