Title Interferometry with Interacting Bose-Einstein Condensates in a Double-Well Potential Author(s) Berrada, Tarik Publication Cham, Springer International Publishing, 2016. Description XIX, 229 p. 89 illus., 67 illus. in color : online resource Abstract Note This thesis demonstrates a full Mach???Zehnder interferometer with interacting Bose???Einstein condensates confined on an atom chip. It relies on the coherent manipulation of atoms trapped in a magnetic double-well potential, for which the author developed a novel type of beam splitter. Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices, both for technological applications and fundamental tests. This requires the development of atom-optics analogues to beam splitters, phase shifters and recombiners. Particle interactions in the Bose???Einstein condensate lead to a nonlinearity, absent in photon optics. This is exploited to generate a non-classical state with reduced atom-number fluctuations inside the interferometer. This state is then used to study the interaction-induced dephasing of the quantum superposition. The resulting coherence times are found to be a factor of three longer than expected for coherent states, highlighting the potential of entanglement as a resource for quantum-enhanced metrology ISBN,Price 9783319272337 Keyword(s) 1.
