  In this paper, we realize a topological superconductor (TSC) in correlated
topological insulator - the interacting spinful Haldane model. We consider the
electrons on the Haldane model with on-site negative-U interaction and then
study its properties by mean field theory and random-phase-approximation (RPA)
approach. We found that in the intermediate interaction region, the ground
state becomes a TSC with the Chern number 2. We also study its edge states and
the zero modes of the pi-flux.
