Nonreciprocal recovery of electromagnetically induced transparency by wavenumber mismatch in hot atoms
Lida Zhang, Nina Stiesdal, Hannes Busche +3
For multi-level systems in hot atomic vapors the interplay between the Doppler shift due to atom velocity and the wavenubmer mismatch between driving laser fields strongly influenc…
Quantum Optics with Rydberg Superatoms
Jan Kumlin, Christoph Braun, Christoph Tresp +3
Quantum optics based on highly excited atoms, also known as Rydberg atoms, has cemented itself as a powerful platform for the manipulation of light at the few-photon level. The Ryd…
Creation of non-classical states of light in a chiral waveguide
Kevin Kleinbeck, Hannes Busche, Nina Stiesdal +3
Creating non-classical states of light from simple quantum systems together with classical resources is a challenging problem. We show how chiral emitters under a coherent drive ca…
Interplay between optomechanics and the dynamical Casimir effect
Alessandro Ferreri, Hannes Pfeifer, Frank K. Wilhelm +2
We develop a model of a quantum field confined within a cavity with a movable wall where the position of the wall is quantized. We obtain a full description of the dynamics of both…
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…
Non-exponential decay of a collective excitation in an atomic ensemble coupled to a one-dimensional waveguide
Jan Kumlin, Kevin Kleinbeck, Nina Stiesdal +3
We study the dynamics of a single excitation coherently shared amongst an ensemble of atoms and coupled to a one-dimensional wave guide. The coupling between the matter and the lig…
