  • Coherent Excitation of the Highly Forbidden Electric Octupole Transition in Yb+ 172 
    Fürst, H.A.; Yeh, C.-H.; Kalincev, D.; Kulosa, A.P.; Dreissen, L.S.; Lange, R.; Benkler, E.; Huntemann, N.; Peik, E.; Mehlstäubler, T.E. (College Park, MD : American Physical Society, 2020)
    We report on the first coherent excitation of the highly forbidden S21/2?F27/2 electric octupole (E3) transition in a single trapped Yb+172 ion, an isotope without nuclear spin. Using the transition in Yb+171 as a reference, ...
  • Mass-selective removal of ions from Paul traps using parametric excitation 
    Schmidt, Julian; Hönig, Daniel; Weckesser, Pascal; Thielemann, Fabian; Schaetz, Tobias; Karpa, Leon (Berlin ; Heidelberg : Springer, 2020)
    We study a method for mass-selective removal of ions from a Paul trap by parametric excitation. This can be achieved by applying an oscillating electric quadrupole field at twice the secular frequency ωsec using pairs of ...
