We are studying ultrafast processes at solid surfaces by laser-based photoelectron spectroscopy and microscopy. Our goal is to gain insights into the interaction between electrons in solids as well as between the electrons and their surroundings. The general impact of our research is to deepen fundamental understanding of many-body interaction at the surfaces and nanostructures of metals, semiconductors, as well as superconductors.
Specifically we will apply time-resolved pump-probe photoelectron spectroscopy, microscopy, and double photoemission spectroscopy to study correlated electrons in solids. The light source will be based on a high repetition rate femtosecond laser system and the associated nonlinear optical setups.
