  • Dynamik des Transports in Quantenpunktsystemen 
    Ubbelohde, Niels (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)
    [no abstract]
  • Measurement of finite-frequency current statistics in a single-electron transistor 
    Ubbelohde, Niels; Fricke, Christian; Flindt, Christian; Hohls, Frank; Haug, Rolf J. (Lausanne : Frontiers Research Foundation, 2012-01)
    Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical ...
  • Quantized current source with mesoscopic feedback 
    Fricke, Lukas; Hohls, Frank; Ubbelohde, Niels; Kaestner, Bernd; Kashcheyevs, Vyacheslavs; Leicht, Christoph; Mirovsky, Philipp; Pierz, Klaus; Schumacher, Hans W.; Haug, Rolf J. (College Park, MD : American Physical Society, 2011)
    We study a mesoscopic circuit of two quantized current sources, realized by nonadiabatic single-electron pumps connected in series with a small micron-sized island in between. We find that quantum transport through the ...
  • Shot-noise at a Fermi-edge singularity: Non-Markovian dynamics 
    Ubbelohde, Niels; Roszak, K.; Hohls, Frank; Maire, Niels; Novotný, T.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    For an InAs quantum dot we study the current shot noise at a Fermi-edge singularity in low temperature cross-correlation measurements. In the regime of the interaction effect the strong suppression of noise observed at ...
  • Spin-dependent shot noise enhancement in a quantum dot 
    Ubbelohde, Niels; Fricke, Christian; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2013)
    The spin-dependent dynamical blockade was investigated in a lateral quantum dot in a magnetic field. Spin-polarized edge channels in the two-dimensional leads and the spatial distribution of Landau orbitals in the dot ...
  • Strong quantum memory at resonant Fermi edges revealed by shot noise 
    Ubbelohde, Niels; Roszak, K.; Hohls, Frank; Maire, N.; Haug, Rolf J.; Novotny, T. (London : Nature Publishing Group, 2012-04-23)
    Studies of non-equilibrium current fluctuations enable assessing correlations involved in quantum transport through nanoscale conductors. They provide additional information to the mean current on charge statistics and the ...
