Controlling Rydberg atom excitations in dense background gases
Tara Cubel Liebisch, Michael Schlagmüller, Felix Engel +13
We discuss the density shift and broadening of Rydberg spectra measured in cold, dense atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating back…
Probing a scattering resonance in Rydberg molecules with a Bose-Einstein condensate
Michael Schlagmüller, Tara Cubel Liebisch, Huan Nguyen +10
We present spectroscopy of a single Rydberg atom excited within a Bose-Einstein condensate. We not only observe the density shift as discovered by Amaldi and Segre in 1934, but a l…
Probing a quantum gas with single Rydberg atoms
Huan Nguyen, Tara Cubel Liebisch, Michael Schlagmüller +5
We present a novel spectroscopic method for probing the \insitu~density of quantum gases. We exploit the density-dependent energy shift of highly excited {Rydberg} states, which is…
