The spectacular progress in the field of ultracold quantum gases is intimately connected with the availability of sophisticated techniques for quantum-level control of internal states, motional states and collisional interactions. Atom chips provide such control in compact, robust, and scalable setups, which makes them attractive for both applications and fundamental studies. Here I report on experiments that use microwave near-fields, provided by a waveguide structure that is fully integrated on an atom chip. We show for the first time combined coherent manipulation of internal and motional...
