Knolle Group : Theory of Quantum Matter

The focus of the group is on condensed matter systems in regimes in which the laws of quantum mechanics are important. In condensed matter physics complex behaviour arises from the interaction of a large number of basic degrees of freedom. It is fascinating to uncover the richness of this behaviour, and to understand the universal principles that organize the physical world. Our research has been centred around one of the great topics of modern physics — the search for unconventional quantum phases in correlated materials, e.g. Quantum Spin Liquids, Unconventional Superconductors or Topological Kondo Insulators. This search does not only lead to a deeper understanding of the fundamental principles driving these phases but has also practical relevance for future quantum technology. The underlying theme of our work is to bridge the gap between novel theories and actual experiments. Advances in the theory of topological phases of matter happen in parallel to developments in materials science. Our group combines both lines of research which is crucial for new discoveries. Our aim is to transfer abstract mathematics to experimentally relevant situations.
