Chair of Theoretical Physics IV
University of Bayreuth | KeyLab coordinator
We try to unravel the electronic structure and dynamics of condensed matter systems. Developing and using (time-dependent) density functional theory plays a major role in our group’s research.
We presently work in the following areas:
- Organic semiconductors:
Studying charge transfer processes, optical absorption, and low-gap donor-acceptor systems - Metal nanoparticles:
Structure and electronic properties of nanoalloys, especially from noble metals, catalytic properties - Photoemission:
Calculating photoemission intensities from first principles, angle resolved, also non-perturbatively and strong field effects - Density functional development:
Orbitalfunctionals, Self-interaction corrections, „Tuned-range-separated“ hybrids, taking into account the particle number discontinuity
