The unique molecular water structure at charged interfaces governs various important interfacial processes in electrochemistry, environmental chemistry, and biology. Despite its great relevance, very little is known about the interfacial water structures, particularly their evolution with depth, which is mainly due to the lack of appropriate experimental techniques.
In their latest work the Nonlinear Interfacial Spectroscopy group presents a novel experimental approach which combines structural sensitivity [more...]

Laurenz Rettig formerly headed the research group “Dynamics of Correlated Materials” in our deopartment and has now been appointed as a professor at the Rheinland-Pfälzische Technische Universität (RPTU) in Kaiserslautern on January 1st, 2026. The aim of his group is to understand complex interaction phenomena in solids, for instance between electrons and lattice or spin excitations combining various complementary ultrafast investigation methods, in particular, time- and angle-resolved [more...]
