Our manuscript on the calculation of full Rydberg-Rydberg interaction potentials including angular dependencies and external electric and magnetic fields is now published as a tutorial paper in J. Phy.s B. Have a look at the published article J. Phys. B, 50, 13 or the preprint arXiv:1612.08053 !
On top, we provide the software for the calculation of such interaction potentials as an open-source project. Both the source code as well as installers for Windows, Linux and Mac OS are freely available at
github. For information about future releases and updates to the software, you can sign our mailing list there.
Our work realizing a single-photon absorber was published in PRL and is featured as an editor’s suggestion!
If you are interested how we saturate a dense atomic sample with one photon and make it transparent for up to 35 subsequent
photons, please take a read.

Our paper on Tailoring Rydberg interactions ( arXiv:1605.00259 ) has been published on the Journal of Physics B as part of the special issue on Rydberg atomic physics.
We have realized a deterministic single-photon absorber
based on the strong Rydberg-Rydberg interactions.

Single-photon absorber based on strongly interacting Rydberg atoms
Together with Ofer Firstenberg and Charles Adams, we have submitted a review on Rydberg EIT to the upcoming special issue “Rydberg atomic physics” in Journal of Physics B.

We are very happy to present our latest work on the single photon transistor! With experimental efforts on the implementation of electric field control, we were able to substantially enhance the transistor tuning it on a Förster resonance. At the same time, the system incorporates a pair state spectroscopy method. Thanks to our theory collaborators Przemek Bienias and Hans Peter Büchler, we can nicely model the source polariton propagation through a gate excitation. We further study the coherence properties of the gate spin-wave and find very good agreement with theory developed by Weibin Li and Igor Lesanovsky.
