  • Kunitski, Maksim; Eicke, Nicolas; Huber, Pia; Köhler, Jonas; Zeller, S.; Voigtsberger, J.; Schlott, Nikolai; Henrichs, Kevin; Sann, H.; Trinter, F.; Schmidt, L.; Kalinin, Anton; Schöffler, M.; Jahnke, T.; Lein, Manfred; Dörner, R. (London : Nature Publishing Group, 2019)
    Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference ...
  • Lützenkirchen-Hecht, D.; Wulff, Daniel; Wagner, R.; Holländer, Ulrich; Maier, Hans Jürgen; Frahm, R. (Bristol : Institute of Physics Publishing, 2016)
    Different thermal treatments were performed for the anti-oxidation of steel surfaces, and the processes were investigated ex-situ and in-situ by surface sensitive reflection mode EXAFS experiments at the Cr and Fe K-edges. ...
  • Arndt, Markus; Bassi, Angelo; Giulini, Domenico; Heidmann, Antoine; Raimond, Jean-Michel (Amsterdam : Elsevier BV, 2011)
    We discuss recent studies on the foundations of quantum physics with photonic, atomic, molecular and micromechanical systems as well as theoretical treatments of the interface between quantum physics and classical observations. ...
  • Windberger, A.; Crespo López-Urrutia, J.R.; Bekker, H.; Oreshkina, N.S.; Berengut, J.C.; Bock, V.; Borschevsky, A.; Dzuba, V.A.; Eliav, E.; Harman, Z.; Kaldor, U.; Kaul, S.; Safronova, U.I.; Flambaum, V.V.; Keitel, C.H.; Schmidt, Piet O.; Ullrich, J.; Versolato, O.O. (College Park, MD : American Physical Society, 2015)
    We measure optical spectra of Nd-like W, Re, Os, Ir, and Pt ions of particular interest for studies of a possibly varying fine-structure constant. Exploiting characteristic energy scalings we identify the strongest lines, ...
  • Shammout, Baraa (Hannover : Gottfried Wilhelm Leibniz Universität, 2020)
    In this work we present the design and the construction of a laser system for cooling an atomic gas of potassium 39K on the D1-Line by gray molasses technique. The seed laser is an Interference-filter-stabilized external-cavity ...
  • Dumke, R.; Volk, M.; Müther, T.; Buchkremer, F.B.J.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2002)
    We experimentally demonstrate novel structures for the realization of registers of atomic qubits: We trap neutral atoms in one- and two-dimensional arrays of far-detuned dipole traps obtained by focusing a red-detuned laser ...
  • Bozhevolnyi, Sergey I.; Evlyukhin, Andrey B.; Pors, Anders; Nielsen, Michael G.; Willatzen, Morten; Albrektsen, Ole (Bristol : IOP Publishing Ltd., 2011)
    We demonstrate that optical transparency can be realized with plasmonic metamaterials using unit cells consisting of detuned electrical dipoles (DED), thereby mimicking the dressed-state picture of the electromagnetically ...
  • Brée, Carsten; Babushkin, Ihar; Morgner, Uwe; Demircan, Ayhan (American Physical Society, 2017)
    We demonstrate an up to now unrecognized and very effective mechanism which prevents filament collapse and allows persistent self-guiding propagation retaining a large portion of the optical energy on axis over unexpected ...
