Dimensional crossover for the beyond-mean-field correction in Bose gases
Tobias Ilg, Jan Kumlin, Luis Santos +2
We present a detailed beyond-mean-field analysis of a weakly interacting Bose gas in the crossover from three to low dimensions. We find an analytical solution for the energy and p…
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…
Emergent universal dynamics for an atomic cloud coupled to an optical wave-guide
Jan Kumlin, Sebastian Hofferberth, Hans Peter Büchler
We study the dynamics of a single collective excitation in a cold ensemble of atoms coupled to a one-dimensional waveguide. The coupling between the atoms and the photonic modes pr…
