Attosecond Science

Real time observation of electron dynamics in matter

The CFEL-ATTO Group develops advanced attosecond technologies to investigate the light-activated dynamics of matter with extreme time resolution. In particular, the main goal of our research is to track and ideally control the electronic motion in systems of increasing complexity, from simple molecules to biochemically relevant molecules and nanoparticles.

Free-electron laser reveals the ultrafast dynamics of photoexcited molecules

CFEL-ATTO contributed to an international collaboration realized at the FLASH free electron laser in Hamburg. Using x-ray photoelectron spectroscopy, the group of researchers succeeded to image charge flows in the modified nucleobase thiouracil (see image). In general, the class of thionucleobases promises a variety of medical applications. The work was led by Prof. Markus Gühr from the University of Potsdam and the results are published in Nature Communications.
