Quantum statistics on atom-ion Feshbach resonances
Joachim Siemund, Fabian Thielemann, Jonathan Grieshaber +5
We investigate three-body recombination in a hybrid atom-ion system consisting of a single trapped Ba ion immersed in a two-component Fermi gas of Li atoms near an atom-ion Fes…
Magnetic Feshbach resonances in Ba+Li collisions due to strong spin-orbit coupling
Masato Morita, Joachim Siemund, Wei Wu +8
We report a pronounced dependence of magnetic Feshbach resonance spectra on the initial hyperfine-Zeeman state of Li in ultracold Ba+Li collisions. The measured num…
Trapping, Shaping and Isolating of Ion Coulomb Crystals via State-selective Optical Potentials
Pascal Weckesser, Fabian Thielemann, Daniel Hoenig +3
For conventional ion traps, the trapping potential is close to independent of the electronic state, providing confinement for ions dependent primarily on their charge-to-mass ratio…
Mass-selective removal of ions from Paul traps using parametric excitation
Julian Schmidt, Daniel Hönig, Pascal Weckesser +3
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 t…
Optical Traps for sympathetic Cooling of Ions with ultracold neutral Atoms
J. Schmidt, P. Weckesser, F. Thielemann +2
We report the trapping of ultracold neutral atoms and ions in a common optical potential in absence of any radiofrequency (RF) fields. We prepare $ \te…
