Abstract

We construct microscopic Hamiltonians for symmetry-preserving topologically ordered states on the surface of topological crystalline superconductors, protected by a Z2 reflection symmetry. Starting from ν Majorana cones on the surface, we show that the semion-fermion topological order emerges for ν=2, and more generally, SO(ν)ν topological order for all ν2 and Sp(n)n for ν=2n when n2.
