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
