In a new publication in Nature with colleagues in California and in Florida, we present the first time-resolved measurement of the chiral state transfer for parameter variations that exclude an exceptional point. From our group, Alex Schumer was the one most involved in this project – congratulations!
Our work on “Transforming Space with Non-Hermitian Dielectrics” was selected as the cover article of Physical Review Letters. Many thanks go to Ivor Krešić, who first-authored this paper and prepared the figure, and to our collaborators Ulf Leonhardt (Weizmann) and Kostas Makris (Heraklion).
Matthias Kühmayer successfully defended his PhD on “Optimal Wave Fields in Complex Scattering Environments” – congratulations! Many thanks also to Gregor Thalhammer and Thomas Weiss for serving as external referees.
Together with the teams of Mercedeh Khajavikhan, Demetri Christodoulides and Patrick LiKamWa we showed how to create topological lasing modes in a laser cavity that steers light around an exceptional point. Congratulations to Alexander Schumer, who spent several months with our partner groups in the US and now serves as the first author of a joint paper in Science. See also the news highlight in Laser Focus World and the press release from TU Wien.
Three letters involving our group have just been published in the Physical Review. The topics range from atomic frequency combs, an invariance property of the Fisher information, to the optimal detection of targets in complex media. Many thanks go to our collaborators in France, India, Germany and in the Netherlands.
Matthias Zens successfully defended his PhD on “Cavity Quantum Electrodynamics with Spin Ensembles: From the Semiclassical to the Quantum Regime” – congratulations! Many thanks also to Johannes Feist and Ulrich Hohenester for serving as external referees.
Helmut Hörner and David Globosits, who worked with us on their master projects, just graduated and will pursue their PhD in our group – congratulations and welcome!
Ulf Leonhardt from the Weizmann Institute of Science in Israel is currently visiting the group in terms of an extended research stay and we enjoy very much the fruitful collaboration with him.
Konstantinos Makris, our previous Marie Skłodowska-Curie fellow in the group and long-term collaborator, obtained tenure at the University of Crete. Congratulations!
An image proposed by Matthias Kühmayer to illustrate our work on `Scattering Invariant Modes´ was selected for the June cover image of Nature Photonics. Congrats to Matthias!
