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.. | | 出版日期 | Book 2016 | | 关键词 | Bose-Einstein condensate interferometry; Trapped BECs; Manipulation of trapped atoms; Ultracold quantum | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-27233-7 | | isbn_softcover | 978-3-319-80097-4 | | isbn_ebook | 978-3-319-27233-7Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2016 |
