Molecular Materials: Light/Matter Interface

Light-matter coupling of a point-like light source

Molecular materials are exciting for physics because they combine the almost unlimited design space of chemistry with the complexity of materials. Among others, questions in this area are: Why does light emerge when electrons tunnel? How can I excite and understand electronic processes in perowskites with light? How can I influence excitons in molecular solids?In these fields we collborate intensively with our colleagues from material science and chemistry.
