Combining laser cooling and Zeeman deceleration for precision spectroscopy in supersonic beams
Gloria Clausen, Laura Gabriel, Josef A. Agner +4
Precision spectroscopic measurements in atoms and molecules play an increasingly important role in chemistry and physics, e.g., to characterize structure and dynamics at long times…
Measuring the polarization of electromagnetic fields using Rabi-rate measurements with spatial resolution: experiment and theory
J. Koepsell, T. Thiele, J. Deiglmayr +2
When internal states of atoms are manipulated using coherent optical or radio-frequency (RF) radiation, it is essential to know the polarization of the radiation with respect to th…
Manipulating Rydberg atoms close to surfaces at cryogenic temperatures
Tobias Thiele, Stefan Filipp, Josef Anton Agner +6
Helium atoms in Rydberg states have been manipulated coherently with microwave radiation pulses near a gold surface and near a superconducting NbTiN surface at a temperature of $3…
Driving Rydberg-Rydberg transitions from a co-planar microwave waveguide
S. D. Hogan, J. A. Agner, F. Merkt +3
The coherent interaction between ensembles of helium Rydberg atoms and microwave fields in the vicinity of a solid-state co-planar waveguide is reported. Rydberg-Rydberg transition…
