Topological Superconductivity in an Extended s-Wave Superconductor and Its Implication to Iron-Based Superconductors
In the presence of both space and time reversal symmetries, an s-wave A_{1g} superconducting state is usually topologically trivial. Here, we demonstrate that an exception can take place in a type of nonsymmorphic lattice structure. We specify the demonstration in a time reversal invariant system wi...
