    We study the tuning mechanisms of Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange interaction between two lateral quantum dots in the Kondo regime. At zero magnetic field we observe the expected splitting of the Kondo resonance ...
  • Smolinsky, T.; Homann, M.; Imbihl, R. (Cambridge : Royal Society of Chemistry, 2016)
    The dynamic behavior of the O2 + H2 reaction on a Rh(111) surface alloyed with Ni has been studied in the 10(-5) mbar range using photoemission electron microscopy (PEEM) as a spatial resolving method. For T = 773 K and ...
  • Krieg, U.; Zhang, Yu; Tegenkamp, Christoph; Pfnür, Herbert (Bristol : IOP Publishing Ltd, 2014)
    We generated arrays of silver wires with a height of 1 atom and an average width of 11 atoms on the Si(557) surface via self-assembly with local √3 x √3 order, and investigated the 1D plasmon formation in them using a ...

    Adsorption of Au on vicinal Si(111) surfaces results in growth of long-range ordered metallic quantum wires. In this paper, we utilized site-specific and selective adsorption of oxygen to modify chemically the transport ...
  • Wolf, Andreas; Kodanek, Torben; Dorfs, Dirk (Cambridge : Royal Society of Chemistry, 2015-10-29)
    Localized surface plasmon resonances (LSPRs) of degenerately doped copper chalcogenide nanoparticles (NPs) (Cu2−xSe berzelianite and Cu1.1S covellite) have been modified applying different methods. The comparison of the ...
  • Hapke-Wurst, I.; Zeitler, U.; Keyser, U.F.; Haug, Rolf J.; Pierz, Klaus; Ma, Z. (College Park, MD : American Institute of Physics, 2003)
    A study was conducted on the onset voltage of resonant tunneling through indium arsenide (InAs) quantum dots by growth parameters. It was found that the onset voltage of the first step decreased from 200 mV to 0 with ...
  • Könemann, Jens; Kubala, Björn; König, Jürgen; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    Single-electron tunneling through a zero-dimensional state in an asymmetric double-barrier resonant-tunneling structure is studied. The broadening of steps in the I-V characteristics is found to strongly depend on the ...
  • de Roode, Stephan R.; Frederikse, Thomas; Siebesma, A. Pier; Ackerman, Andrew S.; Chylik, Jan; Field, Paul R.; Fricke, Jens; Gryschka, Micha; Hill, Adrian; Honnert, Rachel; Krueger, Steven K.; Lac, Christine; Lesage, Andrew T.; Tomassini, Lorenzo (Washington, DC : American Geophysical Union (AGU), 2019)
    To quantify the turbulent transport at gray zone length scales between 1 and 10 km, the Lagrangian evolution of the CONSTRAIN cold air outbreak case was simulated with seven large eddy models. The case is characterized by ...
  • Taubert, Johannes; Brüser, Thomas (Berlin : De Gruyter, 2014)
    Tat systems translocate folded proteins across biological membranes of prokaryotes and plant plastids. TatBC complexes recognize N-Terminal Tat signal peptides that contain a sequence motif with two conserved arginines ...
  • Ketov, Sergei V.; Lechtenfeld, Olaf; Parkes, Andrew J. (College Park (Maryland) : American Physical Society, 1995)
    The most general homogeneous monodromy conditions in N=2 string theory are classified in terms of the conjugacy classes of the global symmetry group U(1,1)⊗openZ2. For classes which generate a discrete subgroup Γ, the ...
  • Joachim, Jutta; Martin, Marlen; Lange, Henriette; Schneiker, Andrea; Dau, Magnus (Abingdon : Taylor and Francis Ltd., 2018)
    Private military and security companies (PMSCs) play an increasingly important role in the provision of security-related services. In their attempts to win new clients and find suitable personnel, they take on different ...
  • Niessen, Markus; Krause, Katrin; Horst, Ina; Staebler, Norma; Klaus, Stephanie; Gaertner, Stefanie; Kebeish, Rashad; Araujo, Wagner L.; Fernie, Alisdair R.; Peterhansel, Christoph (Oxford : Oxford University Press, 2012)
    The major photorespiratory pathway in higher plants is distributed over chloroplasts, mitochondria, and peroxisomes. In this pathway, glycolate oxidation takes place in peroxisomes. It was previously suggested that a ...
  • Lopes, Giseli Rabello; Leme, Luiz André P. Paes; Pereira Nunes, Bernardo; Casanova, Marco Antonio; Dietze, Stefan (Heidelberg : Springer Verlag, 2014)
    Whenever a dataset t is published on the Web of Data, an exploratory search over existing datasets must be performed to identify those datasets that are potential candidates to be interlinked with t. This paper introduces ...
  • van der Zwan, Elmar V.; Lein, Manfred (College Park, MD : American Physical Society, 2010)
    We present a theoretical investigation into the two-center interference in aligned H2+. The influence of the laser field on the recombination step is investigated by comparing laser-induced harmonic generation with harmonic ...
  • Lichtenstein, Timo; Aulbach, J.; Schäfer, J.; Claessen, R.; Tegenkamp, Christoph; Pfnür, Herbert (College Park, MD : American Physical Society, 2016)
    Dimensional crossover is of high relevance to understanding real-world quasi-one-dimensional (1D) systems. Here we study the collective excitations, measured as plasmon dispersions in an electron energy loss experiment, ...
  • Liu, G.; Liu, T.; Xie, Q.; Wang, Q.J. (London : SAGE Publications Ltd., 2008)
    A finite-element deterministic two-dimensional thermal elasto-plastic contact model is presented in this article, which facilitates the investigation of the influence of steady-state frictional heating on contacting ...

    Recent progress in the understanding of vacuum expectation values and of infrared divergences in different regularization schemes is reviewed. Vacuum expectation values are gauge and renormalization-scheme dependent ...
  • Rogge, M.C.; Haug, Rolf J. (College Park, MD : American Physical Society, 2008)
    As an advanced quantum system, a three terminal triple quantum dot with one lead attached to each dot allows us to simultaneously measure a transport along two different paths. Quadruple points with all three dots in ...
