ABSTRACT
Electronic properties of materials are encoded in the symmetry of their atomic or molecular lattice. Examples are ferroelectrics that break space inversion symmetry or ferromagnets that break time reversal symmetry. In recent years it became evident that novel properties can emerge at the nanoscale. In addition to symmetry, also topology, such as vorticity, determines the properties of these materials on the nanoscale. This talk will highlight two demonstrations of such textured materials: 1. polar magnets exhibiting magnetic skyrmions as nanoscale textures and 2. superconductors at high-magnetic field showing finite momentum pairing resulting in the spatial modulation of the superconducting order parameter. Topology thus offers new electronic device opportunities.
