We have realized high-Q nanomechanical resonators in a strong piezoelectric crystalline material: AlN.

Great work by our team Anastasiia, Alexander Jung, Joachim, Hannes and Lauren in collaboration with the growers from Magdeburg.

We welcome Moritz Lange to our team, who joins us for his PhD in January 2024. He will be researching with the maglev team in the frame of our ERC Consolidator grant with the goal to entangle multiple levitated superconducting microparticles. We wish you all the best for your exciting journey!

At the same time we say good bye to Hanlin, who has been a PostDoctoral researcher with us for four years. We learned a lot together on two-dimensional materials, quantum emitters, and moiré physics, which was very exciting. Now, Hanlin went for a PostDoc at DTU in Denmark. We wish you all the best for your future career!

Joint work with the group of Philippe Tassin on realizing a quasi-bound state in the continuum in a cavity optomechanical system has now been published in Phys Rev B. This work analyzes simple experimental setups how to realize a high optical Q optomechanical microcavity. Thanks to the great work by Cindy!

We welcome Paul to our lab who joins the maglev team as a PostDoc. He will join our efforts in coupling the motion of levitated particles to superconducting circuits. Excited to see the first signals! Good luck!

Our paper describing new results related to the two-dimensional material heterobilayer system of MoSe2/WSe2 has been published in Nature communications, read it here.

We have found two types of localized exciton emissions in this heterobilayer system, where we attribute one of them to defect-localized excitons and the other one to moiré-localized excitons. Moreover, at strong excitation and elevated temperatures we observe emission originating from biexcitons – for the first time.

Congrats to this exciting work, mainly to Hanlin, who was the major driving force behind the project! A wonderful collaboration with the groups of Ermin Malic, Sanshui Xiao, Zhipei Sun, and Saroj Dash!
