Optical ion traps for investigation of atom-ion interactions — •Markus Debatin, Pascal Weckesser, Fabian Thielemann, Yannick Minet, Julian Schmidt, Leon Karpa, and Tobias Schaetz — Physikalisches Institut, Albert-Ludwigs Universität Freiburg, Germany
We demonstrate optical trapping of 138Ba+ ions in absence of any rf-confinement for durations of up to 3 seconds 1 as well as optical trapping of Coulomb crystals. With the trapping probability approaching unity for durations of 100 ms and with low heating, and electronic decoherence rates, our results establish optical ion trapping as a novel and robust tool for the manipulation of cold trapped ions, e.g. in atom-ion interaction experiments 2,3. We give an update of our experiments, which combine the Ba+ ion with bosonic 87Rb and fermionic 6Li atoms in order to explore ultracold interactions.
