  • 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, ...
  • 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 ...
  • Gross, Günter (Stuttgart : Gebrüder Borntraeger Verlagsbuchhandlung, 2014)
    This article presents observations and model simulations of wind and temperature in a subway station. The measurements are taken from an experiment with three ultrasonic anemometers at different levels in the underground ...
  • Timmen, L.; Engfeldt, A.; Scherneck, H.-G. (Berlin, Boston : De Gruyter, 2015)
    Annual absolute gravity measurements with a FG5 instrument were performed in Onsala Space Observatory by the Institute of Geodesy of the Leibniz Universität Hannover from 2003 to 2011 and have been continued with the ...
  • Abbott, B.P.; Allen, Bruce; Aufmuth, Peter; Bisht, A.; Danzmann, Karsten; Denker, T.; Heurs, M.; Kaufer, S.; Krueger, C.; Lough, J.D.; Lück, Harald; Sawadsky, A.; Schütte, D.; Steinmeyer, D.; Vahlbruch, H.; Willke, Benno; Wimmer, M.H.; Wittel, H.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    The gravitational-wave signal GW150914 was first identified on September 14, 2015, by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors with ...
  • Rolfes, I. (Göttingen : Copernicus GmbH, 2007)
    In this contribution, different obstacle-based self-calibration techniques for the measurement of the dielectric properties of liquids are investigated at microwave frequencies. The liquid under test is contained inside a ...
  • Bachmann, Jörg; Krueger, Jiem; Goebel, Marc-Oliver; Heinze, Stefanie (Warsaw : Versita, 2016)
    Most recent studies on soil water repellency (WR) were limited to the humous topsoil or to shallow subsoil layers slightly below the main root zone to approximately 0.5 m depth. Hence, the main objective of the present ...

    Introduction: The aim of this study was to determine the mutation patterns of colon cancers through screening of different regions of mitochondrial DNA (mtDNA) in colon cancer patients. Material and methods: In order to ...
  • Westhof, Lena; Köster, Stephan; Reich, Margrit (Amsterdam : Elsevier BV, 2016)
    Nowadays the protection of the marine environment raises increasing academic and public attention. The issue of organic micropollutants is of equally high importance for the marine ecosystems. Maritime vessels are considered ...
  • Birkholz, Simon; Bree, Carsten; Veselic, Ivan; Demircan, Ayhan; Steinmeyer, Günter (London : Nature Publishing Group, 2016)
    We reanalyse the probability for formation of extreme waves using the simple model of linear interference of a finite number of elementary waves with fixed amplitude and random phase fluctuations. Under these model assumptions ...
