Area B - Quantum Magnetism

Research area B is focused on materials and models of strongly interacting electrons, in particular those with local moments and non-trivial magnetic phenomena, together with their interplay with itinerant charge carriers as well as orbital and lattice degrees of freedom. Area B will tackle the following main goals: the search for and synthesis of novel magnetic quantum materials, the study and control of intertwined electronic orders, in particular in complex oxides and calchogenides, the creation and manipulation of nanostructures of quantum magnets, the investigation of quantum criticality in interacting topological systems beyond the Landau-Ginzburg-Wilson paradigm as well as the detection and classification of interaction-driven topological phases.
