Query: Symmetry indicators for topological superconductors   The systematic diagnosis of band topology enabled by the method of "symmetry
indicators" underlies the recent advances in the search for new materials
realizing topological crystalline insulators. Such an efficient method has been
missing for superconductors because the band structure in the superconducting
phase is not usually available. In this work, we establish symmetry indicators
for weak-coupling superconductors that detect nontrivial topology based on the
representations of the metallic band structure in the normal phase, assuming a
symmetry property of the gap function. We demonstrate the applications of our
formulas using examples of tight-binding models and density-functional-theory
band structures of realistic materials.
