Profile

I mainly work with models and effective theories, that provide accurate predictions for various phenomena in solid state physics. Problems involving interactions are notoriously difficult to handle in quantum mechanics - numerically as well as analytically - however, accurate results can often be obtained within mean field theory or perturbation theory. In particular, I am using density functional theory and its extensions, which are implementet in the software package  GPAW, to which I am an active developer

I am particularly interested in

  • New functionals for total energy calculations
  • Excitons and screening in two-dimensional materials
  • Spin-orbit coupling
  • Dzyaloshinskii-Moriya interactions and chiral magnetism
  • Chern-Simons coupling and topological insulators
