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.

Christoph Braun and Florian Christaller join our team as Master students. Welcome!
We are very happy to announce the publication of our work on electrically tuned Förster resonances on Nature Communications. If you are interested in how these resonances boost the nonlinearity on the single photon level, have a read (open access)!

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 welcome Debanuj Chatterjee to our group! Coming from Kolkata he joins our group for three months, funded by the WISE exchange program.
We have realized a deterministic single-photon absorber
based on the strong Rydberg-Rydberg interactions.
Check out the preprint we have put on the arxiv!
Single-photon absorber based on strongly interacting Rydberg atoms
We have written a short theory paper about Rydberg interactions on a Förster resonance. Based on our experimental paper measuring the properties of the optical transistor on electric field tuned Förster resoannces, we discuss the influence of different state combinations on interaction srength, hopping and angular dependence.

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.
You can find the preprint on the arXiv: arXiv:1602.06117
We welcome Yanli Zhou to our group! As Lecturer for theoretical physics at the National University of Defense Technology, she is staying as a guest research with us for one year to work on the theory of Rydberg EIT.
