Topological superconductivity on the honeycomb lattice: Effect of normal state topology and disorder — •Stephan Rachel — School of Physics, University of Melbourne, Australia

The search for topological superconductors is one of the most pressing and challenging questions in condensed-matter and material research. Despite some early suggestions that doping a topological insulator might be a successful recipe to find topological superconductors, to date there is no general understanding of the relationship of the topology of the superconductor and the topology of its underlying normal state system. Here we present an analysis of doped insulators - topological and trivial. Our approach allows us to study and compare superconducting instabilities of different normal state systems and present rigorous results about the influence of the normal state system's topology. If time permits we will also discuss the influence of disorder on topological superconductivity on the honeycomb lattice.
