Abstract given by the source: Quantum materials is a loosely used label for materials where strong correlations, relativistic effects or pronounced quantum mechanical effects give rise to properties beyond a non-relativistic single particle picture. The present project focuses on such materials in general and in particular on three subclasses of materials. The first subtopic is the class of topological insulators where strong spin-orbit coupling gives rise to helical Dirac states at the surface/interface. The work in this field will focus on doping control, spin current frustration, field effect doping and topological phase transitions among other things. As a central enigma of condensed matter physics remains the issue of the microscopic origin of the pairing mechanism in cuprate superconductors. In this case, attention will be focused on understanding the evolution from the Fermi liquid state at high doping into the possible marginal Fermi liquid, pseudogap and strange metal states close to the optimum doping range. A final example is given by the iridates that are receiving increasing attention. In this case the correlation effects have been considered to be minor but recent results suggest that the interplay between correlation and strong spin-orbit coupling can lead to entirely new phases. Here the efforts will focus on the interplay between correlations and spin-orbit coupling as well as on the very interesting prospects of finding Weyl-semimetals and axion insulators in this class of materials.
