  • Kondo effect in a few-electron quantum ring 
    Keyser, U.F.; Fühner, C.; Borck, S.; Haug, Rolf J.; Bichler, M.; Abstreiter, G.; Wegscheider, W. (College Park, MD : American Physical Society, 2003)
    A small tuneable quantum ring with less than ten electrons was shown to exhibit Aharonov-Bohm oscillations as well as Coulomb blockade. At strong coupling to the leads, evidence of a Kondo effect induced by a single spin ...
  • Relationship between frequencies of pressure oscillations and rotor speed under rotating stall 
    Levy, Y.; Pismenny, J.; Reissner, A.; Riess, W. (Berlin : De Gruyter, 2002)
    The correlation between the frequencies of pressure oscillation ωosc and the rotor speed (frequencies of rotor rotation ωRR) under established rotating stall were determined by three methods: directly from the time diagram ...
  • Spin blockade in capacitively coupled quantum dots 
    Rogge, M.C.; Fühner, C.; Keyser, U.F.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2004)
    The spin blockade in capacitively coupled quantum dots was discussed using local anodic oxidation (LAO) and electron beam lithography. The tunability of the interdot coupling as a function of top gate voltage and magnetic ...
  • Wave packet echoes in the motion of trapped atoms 
    Buchkremer, F.B.J.; Dumke, R.; Levsen, H.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2000)
    A new echo technique to access the coherent and dissipative dynamics of atomic wave packet oscillations in trapping potentials was experimentally and systematically validated. By using this technique, the coherence time ...
