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.

New results on arXiv!

transistor2-title-picWe 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.
