Coupling trapped ions to a nanomechanical oscillator
Moritz Weegen, Martino Poggio, Stefan Willitsch
Cold ions in traps are well-established, highly controllable quantum systems with a wide variety of applications in quantum information, precision spectroscopy, clocks and chemistr…
Cold trapped molecular ions and hybrid platforms for ions and neutral particles
Markus Deiß, Stefan Willitsch, Johannes Hecker Denschlag
We review recent progress in the field of cold trapped molecular ions. A new generation of collision and cold chemistry experiments between atoms and ions has emerged, where cold a…
Experimental implementation of laser cooling of trapped ions in strongly inhomogeneous magnetic fields
Christian Mangeng, Yanning Yin, Richard Karl +1
We demonstrate the Doppler laser cooling of Ca ions confined in a segmented linear Paul trap in the presence of a strong quadrupolar magnetic field generated by two perm…
Optimized strategies for the quantum-state preparation of single trapped nitrogen molecular ions
Aleksandr Shlykov, Mikolaj Roguski, Stefan Willitsch
This work examines optimized strategies for the preparation of single molecular ions in well-defined rotational quantum states in an ion trap with the example of the molecular nitr…
Trapping and sympathetic cooling of conformationally selected molecular ions
Lei Xu, Jutta Toscano, Stefan Willitsch
We report the generation, trapping and sympathetic cooling of individual conformers of molecular ions with the example of cis- and trans-meta-aminostyrene. Following conformational…
Conformational and state-specific effects in reactions of 2,3-dibromobutadiene with Coulomb-crystallized calcium ions
Ardita Kilaj, Silvan Käser, Jia Wang +7
Recent advances in experimental methodology enabled studies of the quantum-state and conformational dependence of chemical reactions under precisely controlled conditions in the ga…
Charge transfer of polyatomic molecules in ion-atom hybrid traps: Stereodynamics in the millikelvin regime
Alexandre Voute, Alexander Dörfler, Laurent Wiesenfeld +4
Rate constants for the charge transfer reaction between NH and Rb in the mK regime are measured in an ion-atom hybrid trap and are found to be lower than the Langev…
