Controlled multi-photon subtraction with cascaded Rydberg superatoms as single-photon absorbers
Nina Stiesdal, Hannes Busche, Kevin Kleinbeck +4
The preparation of light pulses with well-defined quantum properties requires precise control at the individual photon level. Here, we demonstrate exact and controlled multi-photon…
Observation of collective decay dynamics of a single Rydberg superatom
Nina Stiesdal, Hannes Busche, Jan Kumlin +3
We experimentally investigate the collective decay of a single Rydberg superatom, formed by an ensemble of thousands of individual atoms supporting only a single excitation due to…
Observation of three-body correlations for photons coupled to a Rydberg superatom
Nina Stiesdal, Jan Kumlin, Kevin Kleinbeck +6
We report on the experimental observation of non-trivial three-photon correlations imprinted onto initially uncorrelated photons through interaction with a single Rydberg superatom…
Extreme fluctuations of active Brownian motion
Patrick Pietzonka, Kevin Kleinbeck, Udo Seifert
In active Brownian motion, an internal propulsion mechanism interacts with translational and rotational thermal noise and other internal fluctuations to produce directed motion. We…
