Back in business

Within 6 months, we have rebuilt our Rydberg apparatus from scratch in our new lab. What was a completely empty room in early April is now the coolest place (2 μK) at SDU. We are currently putting the last touches on our Rydberg excitation system, then we are ready to go! You can see some pictures from the new lab and of the first steps towards single-photon interaction at SDU here.

New Master Student

Nina Stiesdal has joined us as the first new Master student at our new home SDU. She will join the Rydberg superatom experiment for the next 10 months! Velkommen til holdet!

Results on EIT with Rydberg molecules published in PRA

Our work investigating the role of Rydberg molecules in storage and retrieval of single photons has been published in PRA:

I. Mirgorodskiy, F. Christaller, C. Braun, A. Paris-Mandoki, C. Tresp and S. Hofferberth,
”Electromagnetically induced transparency of ultra-long-range Rydberg molecules”
Phys. Rev. A, 96, 011402 (2017)

Very similar results had previously been observed in the MPQ Quantum Dynamics group!

First MOT in our setup

We have trapped the first Rubidium atoms in a magneto-optical trap in our new setup. The black & white image shows the fluorescence from the trapped atoms. The photo shows the optics and magnetic field generating coils required for this trap.MOT2PICT2431
