Chiral Dirac superconductors: Second-order and boundary-obstructed topology

We analyze the topological properties of a chiral p+ip superconductor for a two-dimensional metal and semimetal with four Dirac points. Such a system has been proposed to realize second-order topological superconductivity and host corner Majorana modes. We show that with an additional C_{4} rotation...
