Abstract: We investigate the interplay of particle-hole symmetry and sub-Brillouin zone (sBZ) topology by coupling a so-called Chern dartboard insulator (CDI) to a superconductor (SC) via the proximity effect. We dub the hybrid system, and equivalent intrinsically superconducting phases, a Chern dartboard superconductor (CDSC). I will review the well-studied case of a Chern insulator coupled to a superconductor, focusing on how to construct the phase diagram and understand the evolution of the edge states. I will then use this framework to explore the sBZ topology of CDSCs.
