State-Selective Ionization and Trapping of Single H Ions with (2+1) Multiphoton Ionization
Ho June Kim, Fabian Schmid, David Holzapfel +1
We report on efficient rovibrational state-selective loading of single H molecular ions into a cryogenic linear Paul trap using (2+1) resonance-enhanced multi-photon ionizati…

Quantum control of a single molecular ion
David Holzapfel, Fabian Schmid, Nick Schwegler +5
Science is founded on the benchmarking of theoretical models against experimental measurements, with the challenge that for all but the simplest systems, the calculations required…

Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
