We are a very active group of theorists working on a broad range of topics using many complementary approaches.
Some overarching themes of our research are:
- relativistic quantum-mechanical effects (e.g. spin-orbit coupling) in rare earths and superconductors;
- topological aspects of condensed matter physics;
- light-matter interactions;
- ferroic complex oxides and their interfaces;
- and new quantum phases of matter
The methods range from first-principles simulations, which can describe the electronic structure of particular materials in great detail, to work carried out on more simplified models to which one can apply advanced techniques of quantum many-body theory (from exact solutions via field theory to more computational approaches such as diagrammatic Monte Carlo and tensor networks). We often work very closely with experimentalists, where a model-independent approach based on general considerations, such as symmetry analyses, often fits best.
