The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
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…
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…
Nuclear quadrupole resonances in compact vapor cells: the crossover from the NMR to the NQR interaction regimes
E. A. Donley, J. L. Long, T. C. Liebisch +3
We present the first experimental study that maps the transformation of nuclear quadrupole resonances from the pure nuclear quadrupole regime to the quadrupole-perturbed Zeeman reg…
