The focus of our group`s efforts is to uncover the ultrafast correlated and collective electron dynamics that unfold when complex materials are exposed to intense, ultrashort laser fields. In particular we are interested in the attosecond control and tracing of strongly coupled electron-nuclear dynamics in molecules, of collective electron dynamics in clusters and nanoparticles (such as plasmons), and of non-linear properties of nanostructured solids as a basis for the development of lightwave nanoelectronics. We use multi-dimensional imaging techniques to gain detailed insight into the electron and nuclear dynamics from the interaction of these materials with near-single cycle laser fields of attosecond to femtosecond duration. Together with our collaborators we take the challenges to not only explore the new field of attosecond nanophysics experimentally, but also to tackle the typically complex theoretical description of the phenomena. In doing so, we offer a stimulating environment for students and postdocs.
