Together with Nicholas Lambert, Jevon Longdell, and Harald Schwefel from New Zealand as well as our previous group member Alexander Schumer, we just published a paper in Nature Physics, demonstrating both theoretically and experimentally how to use an exceptional point to control magnon-polaritons. See also the accompanying News&Views from Changhao Meng and Zhenghua An.
At the recent Madrid conference on time-varying media David received the prize for the best presentation by an early career researcher – congratulations!
In a new paper with Max, Lukas and Günther, recently published in Nature Photonics, we explored how artificial intelligence can extract the maximum possible information from distorted optical signals. Using neural networks trained on seemingly chaotic light patterns, we approached — and nearly reached — the theoretical limit of precision, which we showed to be defined by the Cramér–Rao bound. Many thanks go to our collaborators in France (Dorian Bouchet) and Scotland (Ilya Starshynov and Daniele Faccio) as well as to Oliver for creating the great feature image shown on the top left.

Together with the group of Matthieu Davy in Rennes (France) we published a letter in the Physical Review, demonstrating how to optimally focus microwaves on a nonlinear target such as a low-noise amplifier embedded in a disordered environment (see image on the left).
To celebrate the 2025 International Year of Quantum Science and Technology, the University of Göttingen has realized an installation based on our quantum ping-pong paper with Oliver and Dmitry. More information can be found here.
Together with Elena Redchenko and the team of Johannes Fink at ISTA, we just published a Letter in the Physical Review (available through open access) on the observation of periodic microwave pulses being emitted from a multi-qubit ensemble arranged in a spectral frequency comb. Please also check the corresponding press release from TU Wien’s press department.
Oliver Diekmann, who works on his PhD in our group, has recently designed several scientific illustrations for journal covers, press releases and conference presentations – not just for our own group but also for several other teams. Have a look at his new website or get in touch with him if you want to learn more.
Funded by a postdoctoral fellowship from the Excellence Cluster “Quantum Science Austria“, Zeyu Kuang joins the group from Yale University, where he did his PhD with Owen Miller. Welcome Zeyu – we all look forward to the collaboration!
Together with David and Jakob, we published a new paper in Physical Review A, demonstrating that the Floquet scattering matrix for time-periodic photonic systems satisfies a pseudo-unitarity condition. For more information, check out the paper here.
