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.
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!
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)
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.
Johannes Schmidt joins our group as our first master student!
Our joint work with Tilman Pfau’s group about single electrons coupled to Bose-Einstein condensates has been published in Nature.
We have transferred atoms from our magneto-optical trap into the crossed dipole trap for the first time. The image below shows an absorption image of the atoms after releasing them from this trap (and a short time-of-flight of 400us).
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.
Christoph Tresp joins our team as a PhD student.
