Observation of the motional Stark shift in low magnetic fields
Manuel Kaiser, Jens Grimmel, Lara Torralbo-Campo +5
We report on the observation of the motional Stark effect of highly excited Rb Rydberg atoms moving in the presence of a weak homogeneous magnetic field in a vapor cell. Emp…
All-optical measurement of Rydberg state lifetimes
Markus Mack, Jens Grimmel, Florian Karlewski +3
We have developed an all-optical method for measuring the lifetimes of and Rydberg states and demonstrate its capabilities with measurements on a dilute cloud of ultrac…
Measurement and numerical calculation of Rubidium Rydberg Stark spectra
Jens Grimmel, Markus Mack, Florian Karlewski +4
We report on the measurement of Stark shifted energy levels of Rb Rydberg atoms in static electric fields by means of electromagnetically induced transparency (EIT). Electri…
State-selective all-optical detection of Rydberg atoms
Florian Karlewski, Markus Mack, Jens Grimmel +2
We present an all-optical protocol for detecting population in a selected Rydberg state of alkali atoms. The detection scheme is based on the interaction of an ensemble of ultracol…
Quasiclassical theory of quantum defect and spectrum of highly excited rubidium atoms
Ali Sanayei, Nils Schopohl, Jens Grimmel +3
We report on a significant discrepancy between recently published highly accurate variational calculations and precise measurements of the spectrum of Rydberg states in Rb o…
Detrimental adsorbate fields in experiments with cold Rydberg gases near surfaces
H. Hattermann, M. Mack, F. Karlewski +3
We observe the shift of Rydberg levels of rubidium close to a copper surface when atomic clouds are repeatedly deposited on it. We measure transition frequencies of rubidium to S a…
