Topological Electronics and Materials
Our group studies fundamental properties of condensed matter topological phases and their possible application in quantum technologies. For example, topological materials are very promising for future opto/electronic circuits, since computing schemes can be envisaged where e.g. information-carrying surface or edge states are protected by topology. Such circuits are predicted to from a potential realization of fault-tolerant quantum computing schemes. In our research, we explore a wide range of material systems and corresponding topological quantum phenomena.
Topological Electronics and Materials
Our group is interested in two-dimensional van der Waals materials and their heterostructures as model systems to create topological properties by design. To this end, we make use of strong magnetic and spin-orbit proximity effects in atomically thin graphene-based heterostructures to engineer band structures with novel properties. This research is funded within DFG SPP 2244 Physics of vdW heterostructures.
We further apply top-down nanofabrication to imprint superlattices structures into topological materials, which are predicted to host emergent, artificial condensed matter phases with enhanced electronic correlations already at moderate temperatures. This research in funded through the European Union via ERC Starting Grant 2DTopS.
Our group utilizes light-matter coupling in such solid-state superlattices to interrogate the fundamental symmetries and non-equilibrium dynamics of the topologica states by optoelectronic experiments, such as light-driven currents and light-induced anomalous Hall effects.
