Research in the Flick research group is focused on light-matter interactions on a microscopic level in
particular in the strong-coupling regime. We are interested in both the development of new
computational methods to describe these regimes, e.g. quantum-electrodynamical density-functional
theory, or polaritonic coupled-cluster methods, as well as their applications in catalysis, spectroscopy,
quantum-information simulators.
We are also interested in computational studies of quantum emitters for solid-state applications, such as
NV centers in diamond or defects in 2D materials.
