We investigate material properties with ab initio methods

We are a young and enthusiastic team based at the Physics Department of the University of Oldenburg, in Lower Saxony, Germany. We investigate the electronic structure of various materials, from organic molecules and crystals to inorganic semiconductors and hybrid interfaces. The main focus of our research is on light-matter interaction processes in the static and ultrafast dynamic regime. We study

excitations induced by electromagnetic radiation from the infrared to the hard x-ray spectral region. Our research is based on computational methods implementing first-principles quantum-mechanical approaches, based on (time-dependent) density-functional theory and many-body perturbation theory.

To achieve the atomistic control of two-dimensional materials for emerging technological applications, such as valleytronics, spintronics, and single-photon emission, it is of paramount importance to gain an in-depth understanding of their structure–property relationships. In this work, we present...

Finally out! Learn about "Excitons in organic materials: revisiting old concepts with new insights" via Abstract The development of advanced experimental and theoretical methods for the characterization of excitations in materials enables revisiting established concepts that are sometimes misleadingly transferred from one field to another without the necessary disclaimers. This is precisely the situation that occurs for excitons in organic materials: different states of matter and peculiarities related to their structural arrangements and their environment may substantially alter the nature of the photo-induced excited states compared to inorganic semiconductors for which the concept of an exciton was originally developed....
