Atomic Matter Waves in Magnetic Micro Potentials — •Claus Zimmermann — Physikalisches Institut, Universität Tübingen, Auf der Morgenstelle 14, 72076 Tübingen, Germany

With micro fabricated current conductors on the surface of a substrate it is possible to trap atoms in magnetic potentials of almost arbitrary geometry. Since also Bose-Einstein condensates can be loaded into such micro traps the vision of an integrated atom optics becomes realistic. First versions of matter wave interferometers for sensitive detection of forces and accelerations have been demonstrated recently, but also integrated quantum gates for quantum information processing are conceivable. Furthermore, the close distance to the surface of the substrate makes the atoms a sensitive probe for surface effects.
