Observation of Feshbach resonances between a single ion and ultracold atoms
Pascal Weckesser, Fabian Thielemann, Dariusz Wiater +6
Controlling physical systems and their dynamics on the level of individual quanta propels both fundamental science and quantum technologies. Trapped atomic and molecular systems, n…
Trapping Ions and Atoms Optically
Tobias Schaetz
Isolating neutral and charged particles from the environment is essential in precision experiments. For decades, this has been achieved by trapping ions with radio-frequency (rf) f…
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…
A far-off-resonance optical trap for a Ba ion
Thomas Huber, Alexander Lambrecht, Julian Schmidt +2
Optical trapping and ions combine unique advantages of independently striving fields of research. Light fields can form versatile potential landscapes, such as optical lattices, fo…
