Personal profile
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
