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.
In collaboration with Ori Katz’s team, we have shown in this Letter how to design an optical cavity such that a weakly absorbing film inside of it can perfectly absorb coherent laser light that is both spatially and spectrally broadband. Congratulations to Helmut and Lena for developing the theory behind this concept and many thanks to Oliver for the nice figure here on top!
Our lecture Quantum Theory I (presented with Oliver Diekmann, David Globosits and Helmut Hörner in the winter semester 23/24) has been selected as one of the top six finalists for the Best Lecture Award of TU Wien. The final decision will be taken on October 3rd during a ceremony in Kuppelsaal. Fingers crossed!
Together with Lukas Rachbauer, Dorian Bouchet and Ulf Leonhardt we published an invited tutorial in JOSAB on how to find the optimal quantum states of light for micromanipulation and metrology. The article is openly accessible at this link.
Together with the team of Dave Phillips in Exeter and our former group member Michael Horodynski, we published an article in Science Advances that demonstrates how shaping the wavefront of light can be used to create efficient optical tweezers (i.e., very stiff traps for particles). For more details see the press releases of Exeter University and of the Austrian Press Agency.
In a nice collaboration with the team of Romain Fleury at EPFL and our former Marie-Curie fellow Nicolas Bachelard from Bordeaux, we published an article in Nature Physics that demonstrates how audible sound can be used to steer and rotate objects in complex environments. See the News&Views article by Emmanuel Fort and the highlight in Physics World for more information. Here is also a video on how an origami lotus flower is moved through our sound technique.
Congratulations to our faculty’s team participating in the university’s Dragon Boat Cup, where we reached the final and came fourth out of fourteen. Particular thanks go to Max and Luca from our group for participating.
