"Two-wire guides and traps with vertical bias fields on atom chips";
Physical Review A, 72 (2005), 023607-1 - 023607-10.

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 mu m). 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.
