Abstract
Higher-order topological phases are gapped phases of matter that host gapless corner or hinge modes. For the case of superconductors, corner or hinge modes are gapless Majorana modes or Majorana zero modes. To construct three-dimensional higher-order topological superconductors, we consider a topological-insulator/superconductor multilayer under in-plane Zeeman coupling. We found three different types of higher-order topological superconductor phases, a second-order topological superconductor phase with Majorana hinge flat bands, a second-order Dirac superconductor phase with surface Majorana cones and Majorana hinge arcs, and nodal-line superconductor phases with drumhead surface states and Majorana hinge arcs.
