Minimization of ion micromotion using ultracold atomic probes
A. Härter, A. Krükow, A. Brunner +1
We report on a new sensitive method to minimize excess micromotion of an ion in a Paul trap. The ion is placed in an ultracold cloud of neutral Rb atoms in which ionic micromotion…

A single ion as a three-body reaction center in an ultracold atomic gas
Arne Härter, Artjom Krükow, Andreas Brunner +3
We report on three-body recombination of a single trapped Rb^+ ion and two neutral Rb atoms in an ultracold atom cloud. We observe that the corresponding rate coefficient K_3 depen…
