In our recent paper, we have shown that interlayer excitons in bilayer MoS2 exhibit both a high oscillator strength and highly tunable energies in an applied electric field. Owing to this very large tunability, we were able to optically probe the interaction between intra- and interlayer excitons as they were energetically tuned into resonance. These
Daniel Najer was one of the 5 young scientists to win the Swiss Nanotechnology PhD award. The prize is awarded by the company Bühler for Daniel’s publication on an efficient light-matter interface, coupling a semiconductor QD strongly to an optical microcavity. Congratulations!

Our work reporting evidence of a first-order magnetic phase transition in a gated two-dimensional semiconductor, monolayer-MoS2, has been published in Physical Review Letters.
A coherent exchange of a single energy quantum between an “atom” (in our case a gated InAs quantum dot) and an optical cavity has been reported by our group in Nature. We achieve an atom-cavity Cooperativity of 150, and probe the transitions between singly and doubly excited photon-atom system using photon-statistics spectroscopy.
We report at AIP Advances the observation of optical Second Harmonic Generation (SHG) in Single-Layer Indium Selenide (InSe) and demonstrate that the SHG technique can also be applied to encapsulated samples to probe their crystal orientation.
Our Post-doctoral research, Tomek, has been awarded a Marie-Skłdowska-Curie Individual Fellowship! Tomek’s project, entitled “High-Frequency Spin Entanglement Generation in Diamond” (Hi-FrED) aims at establishing the Nitrogen-Vacancy center in diamond not only as spin-coherent, but also as an optically-coherent efficient emitter of single photons. More details about the project, starting in September 2019, can be found
Host: Prof. Dr. Richard J. Warburton, in collaboration with the Quantum Sensing group (prof. Patrick Maletinsky) and the Nano-phononics group (prof. Ilaria Zardo) Fellow: Dr. Tomasz Jakubczyk Core participants: Viktoria Yurgens, Sigurd Flågan, Brendan Shields The ultimate goal of the project is to achieve high-frequency generation of spin-spin entanglement in spatially separated nitrogen vacancy (NV)
