Research Focus

Our research focuses on the theory of light-matter interactions, both for quantum light, often in the form of (nanophotonic) cavity modes, and for classical light, often in the form of ultrashort (attosecond) pulses. Specific topics we study include: developing theoretical frameworks for molecules and materials strongly coupled to confined electromagnetic modes (polaritons); exploring cavity-mediated modifications of chemical reactions and energy transfer; studying quantum optical effects in nanophotonic systems; investigating many-body phenomena in open quantum systems; ultrafast electron dynamics and photoionization processes in atoms and molecules. This work combines approaches from quantum optics, atomic and molecular physics and quantum chemistry, condensed matter physics, and macroscopic quantum electrodynamics. Many of the projects involve advanced simulations and development of novel methods to treat complex systems, partially on high-performance computing clusters.

A useful tool to calculate light-matter interaction strengths can be found on the tools page. Some of the codes we have developed are available as open source software on GitHub.
