| Chiral surface modes (highlighted by blue empty squares and red solid circles) with a hard-wall confinement along the x direction at k z = 0, in the (a) topo-BCS4 or (b) topo-BCS2 phases. The system may be viewed as a stack of many 2D topological superfluids along the y direction. Accordingly, the surface modes of the system may be understood as a collection of the edge modes of these 2D systems. |
