Theoretical condensed matter physics

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 inMagnetism in 2D materials and magnetic anisotropySpin spiral orderMultiferroic properties and magnetoelectric couplingFirst principles Heisenberg models from the magnetic force theoremMagnons and spectral functions from time-dependent density functional theory
