New paper on the flow of Fisher Information in Nature Physics

In collaboration with the team of Ulrich Kuhl in Nice and with Dorian Bouchet in Grenoble, we published an article in Nature Physics that demonstrates how the information that waves acquire about an object flows from this object to an outside observer. From our group Jakob Hüpfl, Felix Russo and Lukas Rachbauer were principally involved in this study – congratulations! See TU Wien’s press release for more information.

Lukas defended his PhD

Lukas Rachbauer successfully defended his PhD thesis on “Classical and Quantum Waves in Complex Environments” – congratulations! Many thanks go to Ben Stickler (from Ulm University) and Thomas Juffmann (from the University of Vienna) for serving as external referees and examinators.

The triggered quantum avalanche

Together with the team of Jörg Schmiedmayer at the Atominstitut, we demonstrated how to halt and then trigger the super-radiant decay of an ensemble of inverted Nitrogen-Vacany spins in diamond. From our group, Oliver performed the calculations, reaching very good agreement with the experimental data. For more details see the corresponding open access paper in Physical Review Letters and the associated press release from TU Wien.
