Research Interests
Quantum many-fermion systems give rise to fascinating collective phenomena such as superconductivity and magnetism that might form the basis for future quantum materials or devices. Our research explores the fundamental mechanisms for these phenomena and the question under which conditions what phases occur in specific model systems on various lattices. The correlated many-fermion systems studied in our group range from unconventional and high-temperature superconductors over non-trivial or topological insulators and graphene nanostructures to many-color ultracold fermion systems. Besides standard many-body-theoretical approach we mainly work with functional renormalization group (fRG) methods that provide effective low-energy actions from which the predominant collective effects can be inferred. Improving these methods is another substantial aspect of our work.
