  • Atom interferometry for tests of general relativity 
    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 ...
  • A high-flux BEC source for mobile atom interferometers 
    Rudolph, Jan; Herr, Waldemar; Grzeschik, Christoph; Sternke, Tammo; Grote, Alexander; Popp, Manuel; Becker, Dennis; Muentinga, Hauke; Ahlers, Holger; Peters, Achim; Laemmerzahl, Claus; Sengstock, Klaus; Gaaloul, Naceur; Ertmer, Wolfgang; Rasel, Ernst Maria (Bristol : IOP Publishing Ltd., 2015-06-01)
    Quantum sensors based on coherent matter-waves are precise measurement devices whose ultimate accuracy is achieved with Bose-Einstein condensates (BECs) in extended free fall. This is ideally realized in microgravity ...
  • A high-flux BEC source for mobile atom interferometers (vol 17, 065001, 2015) 
    Rudolph, Jan; Herr, Waldemar; Grzeschik, Christoph; Sternke, Tammo; Grote, Alexander; Popp, Manuel; Becker, Dennis; Muentinga, Hauke; Ahlers, Holger; Peters, Achim; Laemmerzahl, Claus; Sengstock, Klaus; Gaaloul, Naceur; Ertmer, Wolfgang; Rasel, Ernst Maria (Bristol : IOP Publishing Ltd., 2015-07-09)
    Erratum to: A high-flux BEC source for mobile atom interferometers in: New Journal of Physics 17 (2015) 065001
  • Interacting quantum mixtures for precision atom interferometry 
    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, ...
  • Orbit simulations and optical phase locking techniques for an atom interferometric test of the universality of free fall 
    Velte, Ulrich (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Several aspects of testing the universality of free fall (UFF) with spaceborne atom interferometers are discussed. Theoretical effects that could lead to an (apparent) violation of the UFF are reviewed and the requirements ...
  • Reply to Comment on 'Species-selective lattice launch for precision atom interferometry' 
    Chamakhi, R.; Ahlers, Holger; Telmini, M.; Schubert, C.; Rasel, Ernst Maria; Gaaloul, N. (Bristol : Institute of Physics Publishing, 2016)
    Reply to: Alexander D Cronin and Raisa Trubko: Comment on 'Species-selective lattice launch for precision atom interferometry'. In: New Journal of Physics 18 (2016), Nr. 11, 118001. DOI: https://doi.org/10.1088/1367-2630 ...
  • Species-selective lattice launch for precision atom interferometry 
    Chamakhi, R.; Ahlers, Holger; Telmini, M.; Schubert, C.; Rasel, Ernst Maria; Gaaloul, Naceur (Bristol : Institute of Physics Publishing, 2015)
    Long-baseline precision tests based on atom interferometry require drastic control over the initial external degrees of freedom of atomic ensembles to reduce systematic effects. The use of optical lattices (OLs) is a highly ...
  • Testing the universality of free fall with rubidium and ytterbium in a very large baseline atom interferometer 
    Hartwig, Jonas; Abend, Sven; Schubert, Christian; Schlippert, Dennis; Ahlers, Holger; Posso-Trujillo, Katerine; Gaaloul, Naceur; Ertmer, Wolfgang; Rasel, Ernst Maria (Bristol : IOP Publishing Ltd., 2015-03-20)
    We propose a very long baseline atom interferometer test of Einstein's equivalence principle (EEP) with ytterbium and rubidium extending over 10m of free fall. In view of existing parametrizations of EEP violations, this ...
