An ionic impurity in a Bose-Einstein condensate at sub-microkelvin temperatures
Kathrin S. Kleinbach, Felix Engel, Thomas Dieterle +3
Rydberg atoms immersed in a Bose-Einstein condensate interact with the quantum gas via electron-atom and ion-atom interaction. To suppress the typically dominant electron-neutral i…
Photo-association of trilobite Rydberg molecules via resonant spin-orbit coupling
Kathrin S. Kleinbach, Florian Meinert, Felix Engel +4
We report on a novel method for photo-association of strongly polar trilobite Rydberg molecules. This exotic ultralong-range dimer, consisting of a ground-state atom bound to the R…
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…
Ultracold chemical reactions of a single Rydberg atom in a dense gas
Michael Schlagmüller, Tara Cubel Liebisch, Felix Engel +10
Within a dense environment (atoms/cm) at ultracold temperatures (), a single atom excited to a Rydberg state acts as a reaction center for…
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…
Observation of mixed singlet-triplet Rb Rydberg molecules
Fabian Böttcher, Anita Gaj, Karl M. Westphal +6
We present high-resolution spectroscopy of Rb ultralong-range Rydberg molecules bound by mixed singlet-triplet electron-neutral atom scattering. The mixing of the scatte…
Absolute absorption and dispersion of a rubidium vapour in the hyperfine Paschen-Back regime
Lee Weller, Kathrin S. Kleinbach, Mark A. Zentile +3
Here we report on measurements of the absolute absorption and dispersion properties of an isotopically pure 87Rb vapour for magnetic fields up to and including 0.6 T. We discuss th…
An optical isolator using an atomic vapor in the hyperfine Paschen-Back regime
L. Weller, K. S. Kleinbach, M. A. Zentile +3
A light, compact optical isolator using an atomic vapor in the hyperfine Paschen-Back regime is presented. Absolute transmission spectra for experiment and theory through an isotop…
