Stefan Nimmrichter is now working in the group of Klaus Hornberger at the University of Duisburg-Essen. More information on Stefan's current research interests can be found here.
More on his doctoral thesis "Macroscopic Matter-wave Interferometry" under the supervision of Markus Arndt:
In my thesis I have developed theoretical methods to facilitate, assess, and interpret macroscopic matter-wave interference experiments with molecules and nanoparticles, as conceived and implemented in the Quantum Nanophysics Group at the University of Vienna. I will give a short overview of these methods with a focus on the feasible mass limits of the most recent implementation of the Talbot-Lau near-field interference scheme in Vienna. I will then turn to the question of how to quantify the macroscopicity of mechanical quantum phenomena in general, developing a systematic and observation-based answer. This admits an objective comparison between arbitrary quantum experiments on mechanical systems.
