Phys. Rev. Lett. 86, 1462–1465 (2001)Two-Wire Waveguide and Interferometer for Cold AtomsReceived 21 August 2000; published in the issue dated 19 February 2001 A versatile miniature de Broglie waveguide is formed by two parallel current-carrying wires in the presence of a uniform bias field. We derive a variety of analytical expressions to describe the guide and present a quantum theory to show that it offers a remarkable range of possibilities for atom manipulation on the submicron scale. These include controlled and coherent splitting of the wave function as well as cooling, trapping, and guiding. In particular, we discuss a novel microscopic atom interferometer with the potential to be exceedingly sensitive. © 2001 The American Physical Society URL:
