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.

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.

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.
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.
