  • Cryogenic linear Paul trap for cold highly charged ion experiments 
    Schwarz, M.; Versolato, O.O.; Windberger, A.; Brunner, F.R.; Ballance, T.; Eberle, S.N.; Ullrich, J.; Schmidt, Piet O.; Hansen, A.K.; Gingell, A.D.; Drewsen, M.; Crespo López-Urrutia, J.R. (College Park, MD : American Institute of Physics, 2012)
    Storage and cooling of highly charged ions require ultra-high vacuum levels obtainable by means of cryogenic methods. We have developed a linear Paul trap operating at 4 K capable of very long ion storage times of about ...
  • Deceleration, precooling, and multi-pass stopping of highly charged ions in Be+ Coulomb crystals 
    Schmöger, L.; Schwarz, M.; Baumann, T.M.; Versolato, O.O.; Piest, B.; Pfeifer, T.; Ullrich, J.; Schmidt, Piet O.; Crespo López-Urrutia, J.R. (College Park, MD : American Institute of Physics, 2015)
    Preparing highly charged ions (HCIs) in a cold and strongly localized state is of particular interest for frequency metrology and tests of possible spatial and temporal variations of the fine structure constant. Our versatile ...
  • 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 ...
