Phys. Rev. A 72, 023607 (2005) [10 pages]Two-wire guides and traps with vertical bias fields on atom chipsReceived 17 July 2004; revised 31 March 2005; published 10 August 2005 We present atom chip traps and guides created by a combination of two current-carrying wires and a bias field pointing perpendicular to the chip surface. These elements can be arranged in any orientation on the chip surface. We study loading schemes for the traps and present a detailed study of the guiding of thermal atomic clouds in an omnidirectional matter waveguide along a 25-mm-long curved path at various atom-surface distances (35–450 μm). An extension of the scheme for the guiding of Bose-Einstein condensates is outlined. Such a concept enables utilizing the full two-dimensional surface of the chip. © 2005 The American Physical Society URL:
