  • 0.75 atoms improve the clock signal of 10,000 atoms 
    Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • Atom interferometry with quantized light pulses 
    Soukup, Katharina; Di Pumpo, Fabio; Aßmann, Tobias; Schleich, Wolfgang P.; Giese, Enno (Melville, NY : American Institute of Physics, 2021)
    The far-field patterns of atoms diffracted from a classical light field or from a quantum one in a photon-number state are identical. On the other hand, diffraction from a field in a coherent state, which shares many ...
  • Atom-interferometric test of the universality of gravitational redshift and free fall 
    Ufrecht, Christian; Di Pumpo, Fabio; Friedrich, Alexander; Roura, Albert; Schubert, Christian; Schlippert, Dennis; Rasel, Ernst M.; Schleich, Wolfgang P.; Giese, Enno (College Park, MD : APS, 2020)
    Introducing internal-state transitions simultaneously on each branch of a light-pulse atom interferometer, we propose a scheme that is concurrently sensitive to both violations of the universality of free fall and gravitational ...
  • Gravitational Redshift Tests with Atomic Clocks and Atom Interferometers 
    Di Pumpo, Fabio; Ufrecht, Christian; Friedrich, Alexander; Giese, Enno; Schleich, Wolfgang P.; Unruh, William G. (College Park, MD : American Physical Society, 2021)
    Atomic interference experiments can probe the gravitational redshift via the internal energy splitting of atoms and thus give direct access to test the universality of the coupling between matter-energy and gravity at ...
  • Grossflächiges Sagnac Interferometer mit kalten Atomen 
    Schubert, Christian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2012)

  • Inertial sensing with quantum gases: a comparative performance study of condensed versus thermal sources for atom interferometry 
    Hensel, T.; Loriani, S.; Schubert, C.; Fitzek, F.; Abend, S.; Ahlers, H.; Siemß, J.-N.; Hammerer, K.; Rasel, E.M.; Gaaloul, N. (Berlin ; Heidelberg : Springer, 2021)
    Abstract: Quantum sensors based on light pulse atom interferometers allow for measurements of inertial and electromagnetic forces such as the accurate determination of fundamental constants as the fine structure constant ...
  • Interference of clocks: A quantum twin paradox 
    Loriani, Sina; Abend, Sven; Gaaloul, Naceur; Meiners, Christian; Schubert, Christian; Tell, Dorothee; Wodey, Étienne; Ertmer, Wolfgang; Schlippert, Dennis; Rasel, Ernst M. (Washington : American Association for the Advancement of Science (A A A S), 2019)
    The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational (redshift) time dilation. Hence, it is conceivable that atom interferometers measure ...
  • Ein rauscharmes Materiewellen-Gyroskop hoher Genauigkeit 
    Berg, Peter (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2014)
