Paths Towards Chiral d-wave Superconductivity — •Ronny Thomale — Universität Würzburg, Am Hubland, 97074 Würzburg

Starting by the discovery of integer quantum Hall effect in 1980, chiral topological states of matter have been in the focus of contemporary experimental and theoretical research. Astonishingly, despite significant effort and promising progress e.g. regarding the analysis of strontium ruthenate, unambiguous evidence for a chiral superconducting state of matter has remained an open problem until today. In this talk, we wish to sketch latest efforts to accomplish such an objective, and argue that hexagonal unconventional superconductors appear as one most interesting direction to realise chiral superconductivity which, from a mean field perspective, amounts to realising a Chern insulator of Bogoliubov quasiparticles.
