Our research is within the field of quantum theory of condensed matter systems and quantum information science in the broadest sense (see publications). This includes the study of topological quantum matter, hybrid super-semiconducting systems with exotic quantum states (Majoranas, parafermions, etc.), Luttinger liquids and coupled-wire constructions, strongly interacting electron systems beyond Fermi liquid, topological magnonics and skyrmionics, fractional charge and fractional spin phases, light-matter interaction, (non-linear) transport in nanostructures, atoms on surfaces and Shiba states, spin qubits in semiconducting quantum dots (electron and hole systems), quantum computing, etc.
