Helmut Hörner successfully defended his PhD on “Spectrally and Spatially Degenerate Coherent Perfect Absorbers and a Renormalization-Free Model for Casimir Forces” – congratulations! Many thanks go to Li Ge (CUNY) and Tsampikos Kottos (Wesleyan) for serving as referees for the thesis. Li even made it all the way from NY City to be there in person for the defense (see photo).
