  • Loriani Fard, Sina Leon (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    The search for a fundamental, self-consistent theoretical framework to cover phenomena over all energy scales is possibly the most challenging quest of contemporary physics. Approaches to reconcile quantum mechanics and ...
  • Hinderthür, H.; Pautz, A.; Ruschewitz, F.; Sengstock, K.; Ertmer, Wolfgang (American Physical Society, 1998)
    A special kind of atomic beam splitter using a four-level atomic system in combination with polarized light fields is demonstrated. These specific atom optical elements are used to operate an atom interferometer where the ...
  • Birkl, G.; Buchkremer, F.B.J.; Dumke, R.; Ertmer, Wolfgang (Amsterdam : Elsevier, 2001)
    We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical elements. With these elements versatile and ...
  • Loriani, S.; Schlippert, D.; Schubert, C.; Abend, Sven; Ahlers, H.; Ertmer, Wolfgang; Rudolph, J.; Hogan, J.M.; Kasevich, M.A.; Rasel, E.M.; Gaaloul, N. (Bristol : Institute of Physics Publishing, 2019)
    Recent proposals for space-borne gravitational wave detectors based on atom interferometry rely on extremely narrow single-photon transition lines as featured by alkaline-earth metals or atomic species with similar electronic ...

  • Anders, Fabian (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Entangled ensembles have been created in versatile atomic systems and find a promising application in entanglement-enhanced metrology. Here, entangled spin-states have been successfully applied within interferometers ...
  • Idel, Alexander (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Quantum Sensors, like atom interferometers (AI), can be employed for high-precision measurements of inertial forces, including their application as gravimeters, gradiometers, accelerometers, and gyroscopes. Their ...
  • Schilling, Manuel; Schlippert, Dennis; Schubert, Christian; Wodey, Etienne; Meiners, Christian; Ertmer, Wolfgang; Rasel, Ernst Maria; Müller, Jürgen (Washington D.C. : American Geophysical Union, 2016-12-12)
    A large variety of scientific experiments as well as common applications require more and more precise knowledge of gravity g, its derived quantities, and their change in time. For several phenomena the effect on g can be ...
  • Corgier, R.; Amri, S.; Herr, W.; Ahlers, H.; Rudolph, J.; Guéry-Odelin, D.; Rasel, Ernst Maria; Charron, E.; Gaaloul, Naceur (Bristol : Institute of Physics Publishing, 2018)
    We present a detailed theoretical analysis of the implementation of shortcut-to-adiabaticity protocols for the fast transport of neutral atoms with atom chips. The objective is to engineer transport ramps with durations ...
  • Schilling, Manuel; Wodey, Étienne; Timmen, Ludger; Tell, Dorothee; Zipfel, Klaus; Rasel, Ernst Maria; Müller, Jürgen (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    With the introduction of portable atom interferometers (AI), a genuinely independent method for the determination of g is available for the first time since the introduction of laser interferometer based instruments. Current ...
  • Schilling, Manuel; Wodey, Étienne; Timmen, Ludger; Tell, Dorothee; Zipfel, Klaus H.; Schlippert, Dennis; Schubert, Christian; Rasel, Ernst M.; Müller, Jürgen (Berlin [u.a.] : Springer, 2020)
    Absolute gravimeters are used in geodesy, geophysics and physics for a wide spectrum of applications. Stable gravimetric measurements over timescales from several days to decades are required to provide relevant insight ...

  • Richardson, Logan Latham (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Exploiting the quantum nature of atoms through the use of matter-wave interferometry has lead to the development of devices sensitive to, among other things, the local gravitational acceleration. Measurements of the ...
