The central topic of my research group is the quantum theory of condensed matter systems.
On the one hand, we are concerned with solid-state systems in which strong correlations prevail, so that metals become Mott insulators. Their magnetic properties and elementary excitations, as measured by inelastic scattering methods, interest us. Recently, we have also focused on the topological properties of magnetic excitations that lead to edge modes and are important for magnonics.
On the other hand, physics far from normal equilibrium is fascinating: can open quantum systems be brought into special quantum states when driven by laser pulses on the one hand and relax in contact with large reservoirs on the other hand?
A particularly exciting subfield of this is quantum information processing, with the questions of whether spins can be used as quantum bits or how to optimize quantum gates for switching quantum bits as much as possible so that they are robust against external perturbations. The latter has close links to nuclear magnetic resonance (NMR) and electron spin resonance (ESR).
