We are a young and dynamic research group at the Institute of Applied Physics at the University of Bonn.
Our group explores quantum fluids of light to study emergent many-body phenomena, such as superfluidity or turbulence. Quantum fluids of light can be experimentally realized within microscopic optical cavities, where the photons are trapped in intricate lattice or box potentials. With this experimental platform, we investigate topological physics, the interplay of quantum effects and dissipation, and quantum communication. Unravelling such open questions is at the forefront of today’s research in quantum physics and may lead to new applications for future quantum technologies.
To learn more about our research you can take a look at our previous publications. You can also contact us directly with any questions.
We are always looking for Bachelor and Master students, and offer research projects within the Undergraduate Research Internship Program of the Cluster of Excellence "Matter and Light for Quantum Computing" (ML4Q). More details can be found here.
Latest news
Together with colleagues from RPTU, we have studied the crossover in a quantum gas of light from 2D to 1D. Read it here.
Our project "Dynamical signatures of topological states in photon condensates" receives funding by the DFG.
The Industrie-Club Düsseldorf e.V. and the North Rhine-Westphalian Academy for Sciences and Arts have awarded the Wissenschaftspreis 2024 to Julian Schmitt.
A fundamental relation connecting the temporal fluctuations and the response behaviour has been experimentally observed in a quantum gas made of photons, the particles of light. The validity of this so-called quantum regression theorem could so far not be directly revealed for quantum gases.
Dr. Julian Schmitt from the Institute of Applied Physics at the University of Bonn is to receive the 2023 Rudolf Kaiser Prize, one of the most prestigious accolades in Germany for early-career natural scientists working in the field of physics.
Our first two Bachelor students, Marlon Demmerle and Darius Hoyer, have successfully finished their Bachelor theses in the QFL-Lab! Congratulations!!!
The SFB OSCAR Student iWeek on "Machine Learning in Physics" took place between 28.08. - 01.09.2023 at the Bethe Center for Theoretical Physics in Bonn.
Our experimental confirmation of the validity of the fluctuation-dissipation theorem in a Bose-Einstein condensate is published in Physical Review Letters.
We have measured the emergence of turbulence and its dynamic scaling using a quantum gas of ultracold atoms. Read the paper here.
In his ERC Starting Grant "Non Hermitian Topological Physics in Grand Canonical Photon Lattices", Julian and his team will develop a strategy with which new and topologically protected quantum states can be generated and observed in open systems.
