Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single
experimental setup have recently emerged as a new platform for fundamental research in …

The control of physical systems and their dynamics on the level of individual quanta
underpins both fundamental science and quantum technologies. Trapped atomic and …

Sympathetic cooling of molecular ions with ultracold gases is enabling a new era of
research in chemistry and physics. There has been much progress in this new field in the …

Great advances in precision measurements in the quantum regime have been achieved with
trapped ions and atomic gases at the lowest possible temperatures,–. These successes …

Ultracold atom-ion mixtures are gaining increasing interest due to their potential applications
in ultracold and state-controlled chemistry, quantum computing, and many-body physics …

We report the trap** of ultracold neutral Rb atoms and Ba+ ions in a common optical
potential in absence of any radio frequency (rf) fields. We prepare Ba+ at 370 μ K and …

We report on the observation of cold collisions between Li 6 atoms and Yb+ ions. This
combination of species has recently been proposed as the most suitable for reaching the …

An ion in a radio frequency ion trap interacting with a buffer gas of ultracold neutral atoms is
a driven dynamical system which has been found to develop a nonthermal energy …

We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg
states. The strong polarizabilities of the Rydberg levels increase the interaction strength …

Cryogenic 22-pole ion traps have found many applications in ion-molecule reaction kinetics
and in high resolution molecular spectroscopy. For most of these applications it is important …
