Quantum many-body theory of superconductivity and magnetism

The main focus of the research is on ordered states such as unconventional superconductivity and complex, sometimes topologically non-trivial, magnetic phases. Models are carefully chosen in order to complement the experimental work represented in the IMPRS, and to yield physical insight into iron pnictides, cuprates, topological insulators and superconductors, magnetism in doped semiconductors and magnetic critical phenomena.
