Reaching ultracold temperatures within hybrid atom–ion systems is a major limiting factor for control and exploration of the atom–ion interaction in the quantum regime. In this work, we present results on numerical simulations of trapped ion buff

Trap-assisted complexes in cold atom-ion collisions

Autor: H. Hirzler, E. Trimby, R. Gerritsma, A. Safavi-Naini, J. Pérez-Ríos

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 the Paul trap facilitates the formation of temporary complexes by reduc

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 simulations, we find a crossover from dimer dissociation to molecular ion f

Low-energy collisions of Rydberg atom-ion systems are investigated theoretically. We present the parameter space associated with suitable approaches for the dynamics of Rydberg atom-ion collisions, i.e. quantum-, Langevin and classical exchange regim

Observation of Interactions between Trapped Ions and Ultracold Rydberg Atoms

Autor: H. Fürst, Rene Gerritsma, H. Hirzler, N. V. Ewald, T. Feldker

Publikováno v: Physical Review Letters, 122(25):253401. American Physical Society

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 transfer between the Rydberg atoms and ions, exceeds that of Langevin
