This review discusses progress in the new field of coherent matter waves, particularly with
respect to Bose–Einstein condensates. We give a short introduction to Bose–Einstein …

The experimental realization of Bose–Einstein condensates of dilute gases,, has allowed
investigations of fundamental concepts in quantum mechanics at ultra-low temperatures …

We demonstrate time-resolved counting of single atoms extracted from a weakly interacting
Bose-Einstein condensate of R 87 b atoms. The atoms are detected with a high-finesse …

Impurity atoms propagating at variable velocities through a trapped Bose-Einstein
condensate were produced using a stimulated Raman transition. The redistribution of …

We report the first realization of a guided quasicontinuous atom laser by rf outcoupling a
Bose-Einstein condensate from a hybrid optomagnetic trap into a horizontal atomic …

We report on the atom optical manipulation of an atom laser beam. Reflection, focusing, and
its storage in a resonator are demonstrated. Precise and versatile mechanical control over …

We present and characterize an experimental system in which we achieve the integration of
an ultrahigh finesse optical cavity with a Bose-Einstein condensate (BEC). The conceptually …

We propose a scheme to implement the simplest and best-studied version of the quantum
random walk, the discrete Hadamard walk, in one dimension using a coherent macroscopic …

We analyze the extraction from a trapped Bose-Einstein condensate to a nontrapping state
of a coherent atomic beam and its subsequent fall, at T= 0 K. Our treatment fully takes gravity …

The coherent and collective nature of a Bose–Einstein condensate can enhance or
suppress physical processes. Bosonic stimulation enhances scattering in already occupied …
