Metrology of Rydberg states of the hydrogen atom
Simon Scheidegger, Josef A. Agner, Hansjürg Schmutz +1
We present a method to precisly measure the frequencies of transitions to high- Rydberg states of the hydrogen atom which are not subject to uncontrolled systematic shifts cause…
Precision measurement of the ionization energy of Cs I
Johannes Deiglmayr, Holger Herburger, Heiner Saßmannshausen +3
We present absolute-frequency measurements for the transitions from the 6s ground state of Cs to p and p Rydberg states. The transition freque…
Imaging electric fields in the vicinity of cryogenic surfaces using Rydberg atoms
T. Thiele, J. Deiglmayr, M. Stammeier +4
The ability to characterize static and time-dependent electric fields in situ is an important prerequisite for quantum-optics experiments with atoms close to surfaces. Especially i…
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…
