    Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension and eliminates the gravitational sag for trapped atoms. These ...
  • Popp, Manuel André (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Quantum sensors based on atomic interferometry are becoming valued tools for precision measurements in various research areas such as metrology, Earth sciences and inertial sensors. However, the verification of their ...
  • Lange, K.; Peise, J.; Luecke, B.; Gruber, T.; Sala, A.; Polls, A.; Ertmer, Wolfgang; Julia-Diaz, B.; Santos, L.; Klempt, C. (Bristol : Institute of Physics Publishing (IOP), 2018)
    If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Here, we realize this effect by changing the ...
  • 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 ...
  • Corgier, Robin; Loriani, Sina; Ahlers, Holger; Posso-Trujillo, Katerine; Schubert, Christian; Rasel, Ernst M.; Charron, Eric; Gaaloul, Naceur (Bristol : IOP Publishing Ltd., 2020)
    We present a source engineering concept for a binary quantum mixture suitable as input for differential, precision atom interferometry with drift times of several seconds. To solve the non-linear dynamics of the mixture, ...

    Parametric amplification of vacuum fluctuations is crucial in modern quantum optics, enabling the creation of squeezing and entanglement. We demonstrate the parametric amplification of vacuum fluctuations for matter waves ...

  • Meister, Matthias; Roura, Albert; Rasel, Ernst M.; Schleich, Wolfgang P. (Bristol : Institute of Physics Publishing, 2019)
    Atom laser experiments with Bose-Einstein condensates (BECs) performed in ground-based laboratories feature a coherent and directed beam of atoms which is accelerated by gravity. In microgravity the situation is fundamentally ...
  • Albers, Henning (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    The precision of atom interferometers, targeted for example in the Hannover Very Long Baseline Atom Interferometer (VLBAI) facility, imposes stringent requirements in several respects. They concern the control of ...
  • Lange, Karsten (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    The predictions of quantum mechanics often differ from our everyday experiences. In the classical case, the state of a system can be predicted precisely, assuming the exact knowledge of all parameters. This is not possible ...
