We congratulate Nina Stiesdal on the prize of the best poster at this year’s meeting of the Danish Physical Society 2018! She presented the work of the previous experiments which comprises the observation of two- and three-photon correlations mediated by a single Rydberg superatom.
In a recent experiment we have investigated how a single Rydberg superatom mediates three-body correlations between photons. The experiment follows the line of our previous experiments on a single Rydberg superatom. The observation of three-photon correlations has led to a joint publication with collaborators from Universität Stuttgart.

In a collaboration with theorists from Aarhus University and the Joint Quantum Institute at the University of Maryland, USA, we have studied a new decoherence-suppression mechanism in photon-photon scattering is revealed in a Rydberg electromagnetically-induced transparent medium. We were very happy to see the publication featured as editors choice!

Philipp Lunt has joined us as a new master student. Philipp will work on a new ultracold Ytterbium experiment. Velkommen til holdet!
Simon Ball joins the group at SDU as a Postdoctoral Researcher after finishing his PhD with Charles Adams at Durham University in the UK
In a recent experiment we have investigated the interaction of a propagating few-photon field interacting with an single two-plus-one level system. The system was realized by collectively coupling thousands of atoms to a Rydberg state in order to form a Rydberg superatom.

Free-Space Quantum Electrodynamics with a Single Rydberg Superatom
Phys. Rev. X 7, 41010 (2017)
Within 6 months, we have rebuilt our Rydberg apparatus from scratch in our new lab. What was a completely empty room in early April is now the coolest place (2 μK) at SDU. We are currently putting the last touches on our Rydberg excitation system, then we are ready to go! You can see some pictures from the new lab and of the first steps towards single-photon interaction at SDU here.
Nina Stiesdal has joined us as the first new Master student at our new home SDU. She will join the Rydberg superatom experiment for the next 10 months! Velkommen til holdet!
Our work investigating the role of Rydberg molecules in storage and retrieval of single photons has been published in PRA:
