Since the beginning of this year, Stephan Fritzsche has joined the Helmholtz Institute Jena and the Department of Physics and Astronomy of the Friedrich Schiller University as Professor for theoretical physics. He and his group will strengthen the activities of the institute in the area of relativistic quantum dynamics and strong-field QED and will hence support ongoing research in x-ray science and polarimetry.
During the past years, Fritzsche has worked at Oulu University (Finland) and the Frankfurt Institute of Advanced Studies (FIAS) where his research was focused mainly on the structure and dynamics of finite quantum systems with applications in atomic, optical and nuclear physics. These topics are of great relevance for the research projects FAIR (Facility for Antiproton and Ion Research) at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt as well as the XFEL (X-Ray Free-Electron Laser) at DESY in Hamburg.
In the future, Fritzsche and his group plan to develop new (many-body) techniques for describing the electron dynamics of ions, atoms and plasma in strong fields.
