Welcome to our research group

Ultrafast Phenomena in Solids and at Interfaces

In the focus of our research are microscopic interaction mechanisms of charge, vibration, and magnetic degrees of freedom in condensed matter. We aim at an understanding of energy transfer between these subsystems and energy transport along spatial coordinates and focus on low dimensions and nanostructures.


  • A new ultrafast laboratory will be part of the upcoming research building ACTIVE SITES, see press release.

  • Beamtime at the European XFEL instrument SCS to study ultrafast soft x-ray absorption spectroscopy of molecular films.

The picture shows a team of scientist from the SCS instrument and the Faculty of Physics, University of Duisburg-Essen in the instrument's control room. The various smiling faces indicate that the beamtime was working well.
