Atomic limit and inversion-symmetry indicators for topological superconductors
Anastasiia Skurativska, Titus Neupert, Mark H. Fischer
Abstract
The authors adapt the method of symmetry-indicators to identify nontrivial topological phases in superconductors with inversion symmetry. In particular, they introduce the notion of a trivial, or---in analogy to topological insulators---'atomic' limit for Bogoliubov-de Gennes Hamiltonians as a reference state for the topologically-trivial superconducting phase.
