Trap-assisted complexes in cold atom-ion collisions
H. Hirzler, E. Trimby, R. Gerritsma +2
We theoretically investigate the trap-assisted formation of complexes in atom-ion collisions and their impact on the stability of the trapped ion. The time-dependent potential of t…
Ultracold ion-atom experiments: cooling, chemistry, and quantum effects
Rianne S. Lous, Rene Gerritsma
Experimental setups that study laser-cooled ions immersed in baths of ultracold atoms merge the two exciting and well-established fields of quantum gases and trapped ions. These ex…
Observation of Chemical Reactions between a Trapped Ion and Ultracold Feshbach Dimers
H. Hirzler, R. S. Lous, E. Trimby +3
We measure chemical reactions between a single trapped Yb ion immersed in an ultracold bath of Li atoms containing trace amounts of Li dimers. This produces LiY…
Buffer gas cooling of ions in time-dependent traps using ultracold atoms
E. Trimby, H. Hirzler, H. Fürst +3
For exploration of quantum effects with hybrid atom-ion systems, reaching ultracold temperatures is the major limiting factor. In this work, we present results on numerical simulat…
Controlling the nature of a charged impurity in a bath of Feshbach dimers
Henrik Hirzler, Eleanor Trimby, Rianne S. Lous +3
We theoretically study the dynamics of a trapped ion that is immersed in an ultracold gas of weakly bound atomic dimers created by a Feshbach resonance. Using quasi-classical simul…
Experimental setup for studying an ultracold mixture of trapped Yb-Li
H. Hirzler, T. Feldker, H. Fürst +7
We describe and characterize an experimental apparatus that has been used to study interactions between ultracold lithium atoms and ytterbium ions. The preparation of ultracold clo…
Observation of Interactions between Trapped Ions and Ultracold Rydberg Atoms
N. V. Ewald, T. Feldker, H. Hirzler +2
We report on the observation of interactions between ultracold Rydberg atoms and ions in a Paul trap. The rate of observed inelastic collisions, which manifest themselves as charge…
Prospects of reaching the quantum regime in Li-Yb mixtures
H. A. Fürst, N. V. Ewald, T. Secker +3
We perform numerical simulations of trapped Yb ions that are buffer gas cooled by a cold cloud of Li atoms. This species combination has been suggested to be the mo…
Cold hybrid ion-atom systems
Michał Tomza, Krzysztof Jachymski, Rene Gerritsma +4
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 quantum…
Observation of collisions between cold Li atoms and Yb ions
J. Joger, H. Fürst, N. Ewald +3
We report on the observation of cold collisions between Li atoms and Yb ions. This combination of species has recently been proposed as the most suitable for reaching the q…
Trapped ions in Rydberg-dressed atomic gases
T. Secker, N. Ewald, J. Joger +3
We theoretically study trapped ions that are immersed in an ultracold gas of Rydberg-dressed atoms. By off-resonant coupling on a dipole-forbidden transition, the adiabatic atom-io…
