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!

Fabian joined the 794. WE-Heraeus-Seminar in Bad Honnef on Exploiting Levitated Particles in the Quantum Regime. He presented our work on levitating superconducting microparticles. Great to join the levitation community!

Our work on microcavity-based optomechanics got published in Optics Express. Congrats to the team, a wonderful and essential collaboration between experiment and theory.

Our work shows that we get optomechanical effects beyond “canonical optomechanics” in a cavity optomechanical systems that confines light to micron-scale length with the help of a photonic crystal mirror and DBR. Have a read here.

Today Karim joined us for his 1 year Master thesis, which he will perform at our maglev experiment. We wish you all the best and look forward to research together with you.

We welcome Alexander Jung who joins our optomechanics team. Alexander did his Master thesis at the Walther-Meissner-Institute in Garching, Germany and will now do his PhD with us. His goal is to increase the optomechanical coupling strength and at the same time reduce the optical lossses. towards single photon strong coupling …
A warm welcome!
