  • Noise enhancement due to quantum coherence in coupled quantum dots 
    Kießlich, G.; Schöll, E.; Brandes, T.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2007)
    We show that the intriguing observation of noise enhancement in the charge transport through two vertically coupled quantum dots can be explained by the interplay of quantum coherence and strong Coulomb blockade. We ...
  • Picosecond near-to-mid-infrared absorption of pulse-injected small polarons in magnesium doped lithium niobate 
    Freytag, Felix; Booker, Philip; Corradi, Gabor; Messerschmidt, Simon; Krampf, Andreas; Imlau, Mirco (Washington, DC : Optical Society of America, 2018)
    Femtosecond-pulse-induced (Epump = 2:5 eV) picosecond infrared absorption is studied in the spectral region between 0.30 eV and 1.05 eV in LiNbO3:Mg. We find a noninstantaneous mid-infrared absorption peak in the time ...
