Theoretical Solid-State Physics

The TSSP group investigates light-matter interactions on a microscopic scale. We develop and use advanced theoretical and computational methods derived from quantum mechanical first principles to describe the dynamics of electronic and atomic excitations. This enables us to analyze and predict various optical properties, such as absorption, luminescence, and resonant Raman spectra. Recently, the group has focused on a quantitative description of the influence of the electron- and exciton-phonon interaction on these spectroscopic properties. We particularly apply our methods to 2D materials and semiconductors that are interesting for the development of novel opto-electronic devices, such as sensors and solar cells.
