    Sympathetic Coulomb crystallization of highly charged ions, retrapped in a cryogenic radiofrequency trap, is demonstrated by an over seven orders-of-magnitude decrease in motional temperature.
  • Menze, Moritz; Heipke, Christian; Geiger, Andreas (Heidelberg : Springer Verlag, 2015)
    We propose to look at large-displacement optical flow from a discrete point of view. Motivated by the observation that sub-pixel accuracy is easily obtained given pixel-accurate optical flow, we conjecture that computing ...
  • Regul, J.; Keyser, U.F.; Paesler, M.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Malavé, A.; Oesterschulze, E.; Reuter, D.; Wieck, A.D. (College Park, MD : American Institute of Physics, 2002)
    We use the all-diamond tip of an atomic force microscope for the direct engraving of high-quality quantum point contacts in GaAs/AlGaAs heterostructures. The processing time is shortened by two orders of magnitude compared ...
  • Berski, Fabian; Hübner, Jens; Oestreich, Michael; Ludwig, Arne; Wieck, A.D.; Glazov, Mikhail (College Park, MD : American Physical Society, 2015)
    We present spin-noise spectroscopy measurements on an ensemble of donor-bound electrons in ultrapure GaAs:Si covering temporal dynamics over 6 orders of magnitude from milliseconds to nanoseconds. The spin-noise spectra ...
  • Borchert, M.J.; Blessing, P.E.; Devlin, J.A.; Harrington, J.A.; Higuchi, T.; Morgner, J.; Smorra, C.; Wursten, E.; Bohman, M.; Wiesinger, M.; Mooser, A.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (College Park, MD : American Physical Society, 2019)
    We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron quantum transition rates of 6(1) quanta/h ...
  • Cala’Lesina, Antonio; Goodwill, Dominic; Bernier, Eric; Ramunno, Lora; Berini, Pierre (Washington, DC : OSA - The Optical Society, 2020)
    Optical phased arrays are of strong interest for beam steering in telecom and LIDAR applications. A phased array ideally requires that the field produced by each element in the array (a pixel) is fully controllable in phase ...
  • Langer, Thomas; Förster, D.F.; Busse, C.; Michely, T.; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2011)
    The sheet plasmon of graphene on Ir(111) was investigated in this paper by means of high-resolution electron energy loss spectroscopy. The perfect lateral coordination of sp2-hybridized C atoms on a large scale is manifested ...
  • Armano, M.; Audley, H.; Auger, G.; Baird, J.T.; Bassan, M.; Binetruy, P.; Born, Michael; Bortoluzzi, D.; Brandt, N.; Caleno, M.; Carbone, L.; Cavalleri, A.; Cesarini, A.; Ciani, G.; Congedo, G.; Cruise, A.M.; Danzmann, Karsten; De Deus Silva, M.; De Rosa, R.; Diaz-Aguiló, M.; et al. (College Park, MD : American Physical Society, 2016)
    We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate that two free-falling reference test masses, such as those needed for a space-based gravitational wave observatory like LISA, ...
  • Walther, C.; Rothe, J.; Schimmelpfennig, B.; Fuss, M. (Cambridge : Royal Society of Chemistry, 2012)
    Tetravalent thorium exhibits a strong tendency towards hydrolysis and subsequent polymerization. Polymeric species play a crucial role in understanding thorium solution chemistry, since their presence causes apparent ...
