Calculations of Rydberg interaction potentials

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.

New results published in PRL!

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.

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)!

Rydberg interactions on a Förster resonance

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.
