State-selected preparation of molecular ions for precision measurements in radio-frequency traps
Daniel Y. Knapp, Maximilian Beyer
The application of mass-analyzed threshold ionization (MATI) for the state-selective preparation of molecular ions is presented. Based on photoexcitation of long-lived high- Ryd…

Laser cooling Rydberg molecules -- a detailed study of the helium dimer
LucÃa Verdegay, Bingcheng Zeng, Daniel Y. Knapp +2
The helium dimer in its metastable triplet state is a promising candidate to be the first laser-cooled homonuclear molecule. An ultracold gas of He would enable a new generat…

Spectroscopy and modeling of Yb Rydberg states for high-fidelity two-qubit gates
Michael Peper, Yiyi Li, Daniel Y. Knapp +8
Highly excited Rydberg states and their interactions play an important role in quantum computing and simulation. These properties can be predicted accurately for alkali atoms with…
