Topological odd-parity superconductors
Topological odd-parity superconductors
We investigate topological phases of full-gapped odd-parity superconductors without or with time-reversal invariance. For odd-parity superconductors, a combination of the inversion and the $U(1)$ gauge symmetry is manifestly preserved, and the combined symmetry enables us to characterize the topological phases from the knowledge of the electron dispersion.
