  • Detection of motional ground state population of a trapped ion using delayed pulses 
    Gebert, Florian; Wan, Yong; Wolf, F.; Heip, J.C.; Schmidt, Piet O. (Bristol : Institute of Physics Publishing, 2016)
    Efficient preparation and detection of the motional state of trapped ions is important in many experiments ranging from quantum computation to precision spectroscopy. We investigate the stimulated Raman adiabatic passage ...
  • Efficient sympathetic motional-ground-state cooling of a molecular ion 
    Wan, Yong; Gebert, Florian; Wolf, Fabian; Schmidt, Piet O. (College Park, MD : American Physical Society, 2015)
    Cold molecular ions are promising candidates in various fields ranging from precision spectroscopy and test of fundamental physics to ultracold chemistry. Control of internal and external degrees of freedom is a prerequisite ...
  • Precision measurement of the isotopic shift in calcium ions using photon recoil spectroscopy 
    Gebert, Florian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015)
    [no abstract]
  • Quantum Algorithmic Readout in Multi-Ion Clocks 
    Schulte, M.; Lörch, N.; Leroux, I.D.; Schmidt, Piet O.; Hammerer, K. (College Park, MD : American Physical Society, 2016)
    Optical clocks based on ensembles of trapped ions promise record frequency accuracy with good short-term stability. Most suitable ion species lack closed transitions, so the clock signal must be read out indirectly by ...
  • Sympathetic cooling of mixed-species two-ion crystals for precision spectroscopy 
    Wübbena, Jannes B.; Amairi, Sana; Mandel, Olaf; Schmidt, Piet O. (College Park, MD : American Physical Society, 2012)
    Sympathetic cooling of trapped ions has become an indispensable tool for quantum-information processing and precision spectroscopy. In the simplest situation a single Doppler-cooled ion sympathetically cools another ion ...
  • Tunable dual-species Bose-Einstein condensates of 39K and 87Rb 
    Wacker, L.; Jørgensen, N.B.; Birkmose, D.; Horchani, R.; Ertmer, Wolfgang; Klempt, Carsten; Winter, N.; Sherson, J.; Arlt, Jan J. (College Park : American Physical Society, 2015)
    We present the production of dual-species Bose-Einstein condensates (BECs) of 39K and 87Rb. Preparation of both species in the |F=1,mF=−1⟩ state enabled us to exploit a total of three Feshbach resonances, which allows for ...
