We are interested in the optical, electronic and quantum optical properties of different material systems, which we analyse by microscopic theory and numerical simulations. For example, we investigate situations in which matter is excited by very short laser pulses. This allows us to study in detail ultrafast dynamical processes that occur on time scales of a few femtoseconds (1 fs = 10-15 s) or even in the range of attoseconds (1 as = 10-18 s). Nonlinearities resulting from the interaction with very intense light pulses can drastically change the optical properties. Besides purely optical processes, optically induced transport phenomena are also of great interest. Furthermore, a strong focus is on investigating interactions with quantum light, which sheds new light on the fundamentals of the interaction between light and matter and is very promising for various applications in quantum technology.


We are a diverse international team working on the different topics and projects.
