My research interest lies in the experimental investigation of photochemical processes on the single molecule level. One of our goals is to reduce the complexity of the systems to the core functional units. This allows us to resolve the molecular processes with high resolution and to explore quantum phenomena otherwise covered in the convoluted response of the material system. For this purpose, we develop multidisciplinary experimental techniques combining molecular and cluster beam spectroscopy with ultrafast laser technology from the visible to the extreme ultraviolet spectral domain. In particular, we apply interferometric and multidimensional femtosecond spectroscopy for high spectro-temporal resolution. We extended these techniques to gas-phase systems and the extreme ultraviolet spectral domain and incorporated highly selective photoelectron and ion-mass spectroscopy techniques. Our samples are prepared in ultrahigh vacuum environments where isolated molecules are studied in cold jets or deposed in rare-gas clusters. In these nanoconfined systems we study ultrafast light-induced conversion processes as well as system-bath interactions using two-dimensional electronic spectroscopy. Using related techniques, we investigate interactions in highly dilute many-body systems and study few-body correlations and cooperative dynamics with XUV interferometry.

This research is integrated in the following projects:

Phasenmodulierte nichtlineare kohärente Spektroskopie (PHANCY)

Kohärente nichtlineare Spektroskopie im XUV-Bereich (CHOISE)

Multidimensionale interferometrische Photoelektronenspektroskopie mit XUV-Photonen (MULTIPLEX) (MULTIPLEX)
