Energy scaling of cold atom-atom-ion three-body recombination
Artjom Krükow, Amir Mohammadi, Arne Härter +3
We study three-body recombination of Ba + Rb + Rb in the mK regime where a single Ba ion in a Paul trap is immersed into a cloud of ultracold Rb atoms. We…
Cold atom-ion experiments in hybrid traps
Arne Härter, Johannes Hecker Denschlag
In the last 5 years, a novel field of physics and chemistry has developed in which cold trapped ions and ultracold atomic gases are brought into contact with each other. Combining…
Long-term drifts of stray electric fields in a Paul trap
Arne Härter, Artjom Krükow, Andreas Brunner +1
We investigate the evolution of quasi-static stray electric fields in a linear Paul trap over a period of several months. Depending on how these electric fields are initially induc…
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…
An apparatus for immersing trapped ions into an ultracold gas of neutral atoms
Stefan Schmid, Arne Härter, Albert Frisch +2
We describe a hybrid vacuum system in which a single ion or a well defined small number of trapped ions (in our case Ba or Rb) can be immersed into a cloud of ultracold neu…
