  • Schwennicke, C.; Pfnür, Herbert (College Park, MD : American Physical Society, 1997)
    Based on low-energy electron diffraction structural investigations of ordered and disordered phases of O/Ni(111) that show that occupation of both fcc and hcp sites can be forced either by thermal activation or by coverage, ...
  • Schülke, Immo; Delecat, Stefan (Hannover : Universität Hannover. Institut für Geologie und Paläontologie, 1998)
    For the first time, in this study NW-German coral and reef localities are comprised. Three well exposed and developed reefal units, which have been analyzed by a working group located at the Institut für Geologie und ...
  • Elbracht, Jörg; Helm, Carsten (Hannover : Universität Hannover. Institut für Geologie und Paläontologie, 1998)
    Upper-Jurassic geschiebe-corals (Thamnasteria concinna) from a gravel-/sandpit at Freden/Leine are described. They are slightly bored by bivalves (Gastrochaenolites) and worms (Trypanites). Some oysters (Nanogyra Inana) ...
  • Mech, Roland; Marques, Ferran (Heidelberg : SpringerOpen, 2002)
    The objective evaluation of 2D-shape estimation results for moving objects in a video sequence is still an open problem. First approaches in the literature evaluate the spatial accuracy and the temporal coherency of the ...
  • Aufmuth, Peter; Danzmann, Karsten; Hage, B.; Kwee, P.; Lueck, H.; Meier, Tobias; Thuering, A.; Willke, Benno; et al. (Bristol : IOP Publishing Ltd., 2009)
    We introduce a novel cooling technique capable of approaching the quantum ground state of a kilogram-scale system-an interferometric gravitational wave detector. The detectors of the Laser Interferometer Gravitational-wave ...
  • Sukhodub, G.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    The propagation of edge magnetoplasmons (EMP) in a degenerated two-dimensional electron gas was analyzed. Investigations show that an interedge EMP mode attributed to the excitations of boundary between two regions with ...
  • Brand, C.; Pfnür, Herbert; Landolt, G.; Muff, S.; Dil, J.H.; Das, Tanmoy; Tegenkamp, Christoph (London : Nature Publishing Group, 2015)
    Quantum wires with spin-orbit coupling provide a unique opportunity to simultaneously control the coupling strength and the screened Coulomb interactions where new exotic phases of matter can be explored. Here we report ...
  • Abbott, B.P.; Abbott, R.; Abbott, T.D.; Abernathy, M.R.; Acernese, F.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from ...
  • Smorra, C.; Mooser, A.; Besirli, M.; Bohman, M.; Borchert, M.J.; Harrington, J.; Higuchi, T.; Nagahama, H.; Schneider, G.L.; Sellner, S.; Tanaka, T.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (Amsterdam : Elsevier BV, 2017)
    We report on the detection of individual spin quantum transitions of a single trapped antiproton in a Penning trap. The spin-state determination, which is based on the unambiguous detection of axial frequency shifts in ...
  • Dettmer, S.; Hellweg, D.; Ryytty, P.; Arlt, Jan J.; Ertmer, Wolfgang; Sengstock, K.; Petrov, D.S.; Shlyapnikov, G.V.; Kreutzmann, H.; Santos, Luis; Lewenstein, M. (American Physical Society, 2001)
    The occurrence of phase fluctuations due to thermal excitations in Bose-Einstein condensates (BECs) is studied for a variety of temperatures and trap geometries. We observe the statistical nature of the appearance of phase ...
  • Räsänen, E.; Mühle, A.; Aichinger, M.; Haug, Rolf J. (College Park, MD : American Physical Society, 2011)
    We observe strong signatures of spin flips in quantum rings exposed to external magnetic fields in the Coulomb blockade regime. The signatures appear as a pattern of lines corresponding to local reduction of conductance, ...
  • Schmitz, Gerd; Mohammadi, Bahram; Hammer, Anke; Heldmann, Marcus; Samii, Amir; Münte, Thomas F.; Effenberg, Alfred O. (London : BioMed Central Ltd., 2013)
    Background: Producing sounds by a musical instrument can lead to audiomotor coupling, i.e. the joint activation of the auditory and motor system, even when only one modality is probed. The sonification of otherwise mute ...
  • Schmidt, T.; Haug, Rolf J.; Fal'ko, V.I.; v. Klitzing, K.; Förster, A.; Lüth, H. (College Park, MD : American Physical Society, 1997)
    The local density of states of heavily doped GaAs is explored at high magnetic fields, where only a single or few Landau bands are occupied. Our experiment is based on resonant tunneling through impurity states and images ...
  • Sukhodub, G.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2005)
    We study the propagation of edge magnetoplasmons by time-resolved current measurements in the quantum Hall regime. Using selective detection of edge states we distinguish two modes of edge excitations propagating with ...
