In this paper we study an s-wave topological superconductor (SC) with a square vortex lattice. We proposed a topological Majorana lattice model to describe this topological state which was supported by the numerical calculations. We found that the Majorana lattice model is really a “topological SC” on the parent topological SC. Such hierarchy structure becomes a new holographic feature of the topological state.
