  • Double-slit photoelectron interference in strong-field ionization of the neon dimer 
    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 ...
  • Ex-situ and in-situ investigations of thermal anti-oxidation treatments of stainless steels by reflection mode EXAFS 
    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. ...
  • Fundamental frontiers of quantum science and technology 
    Arndt, Markus; Bassi, Angelo; Giulini, Domenico; Heidmann, Antoine; Raimond, Jean-Michel (Amsterdam [u.a.] : Elsevier, 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. ...
  • Identification of the predicted 5s-4f level crossing optical lines with applications to metrology and searches for the variation of fundamental constants 
    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, ...
  • Interlayer configurations of self-assembled folded graphene 
    Bockhorn, L.; Rode, J.C.; Gnörich, L.; Zuo, P.; Brechtken, B.; Haug, R.J. (Melville, NY : American Inst. of Physics, 2021)
    The relative orientation between atomic lattices in twisted bilayer graphene opens up a whole new field of rich physics. So, the study of self-assembled twisted bilayer graphene gives deep insight into its underlying growth ...
  • A Laser System for Gray-Molasses Cooling on the D1 Transition of an Atomic Gas of 39K 
    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 ...
  • LISA pathfinder performance confirmed in an open-loop configuration: Results from the free-fall actuation mode 
    Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Castelli, E.; Cavalleri, A.; Cesarini, A.; Cruise, A.M.; Danzmann, K.; De Deus Silva, M.; Diepholz, I.; Dixon, G.; Dolesi, R.; Ferraioli, L.; Ferroni, V.; Fitzsimons, E.D.; Freschi, M.; Gesa, L.; Gibert, F.; Giardini, D.; Giusteri, R.; Grimani, C.; Grzymisch, J.; Harrison, I.; Hartig, M.-S.; Heinzel, G.; Hewitson, M.; Hollington, D.; Hoyland, D.; Hueller, M.; Inchauspé, H.; Jennrich, O.; Jetzer, P.; Karnesis, N.; Kaune, B.; Korsakova, N.; Killow, C.J.; Lobo, J.A.; Liu, L.; López-Zaragoza, J.P.; Maarschalkerweerd, R.; Mance, D.; Meshksar, N.; Martín, V.; Martin-Polo, L.; Martino, J.; Martin-Porqueras, F.; Mateos, I.; McNamara, P.W.; Mendes, J.; Mendes, L.; Nofrarias, M.; Paczkowski, S.; Perreur-Lloyd, M.; Petiteau, A.; Pivato, P.; Plagnol, E.; Ramos-Castro, J.; Reiche, J.; Robertson, D.I.; Rivas, F.; Russano, G.; Slutsky, J.; Sopuerta, C.F.; Sumner, T.; Texier, D.; Thorpe, J.I.; Vetrugno, D.; Vitale, S.; Wanner, G.; Ward, H.; Wass, P.J.; Weber, W.J.; Wissel, L.; Wittchen, A.; Zweifel, P. (College Park, MD : American Physical Society, 2019)
    We report on the results of the LISA Pathfinder (LPF) free-fall mode experiment, in which the control force needed to compensate the quasistatic differential force acting on two test masses is applied intermittently as a ...
  • Micro-optical Realization of Arrays of Selectively Addressable Dipole Traps: A Scalable Configuration for Quantum Computation with Atomic Qubits
