This is the website of the Rotter group at the Institute for Theoretical Physics, Vienna University of Technology (TU Wien). Our main scientific interests are the propagation of waves through complex media, non-Hermitian physics and theoretical quantum optics.

News and latest research

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.
