Epidemic spreading and herd immunity in a driven non-equilibrium system of strongly-interacting atoms
Dong-Sheng Ding, Zong-Kai Liu, Hannes Busche +4
It is increasingly important to understand the spatial dynamics of epidemics. While there are numerous mathematical models of epidemics, there is a scarcity of physical systems wit…
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…
Storage and control of optical photons using Rydberg polaritons
D. Maxwell, D. J. Szwer, D. P. Barato +6
We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polarito…
