WebSeveral experimental and theoretical arguments have been made in favor of a d-wave symmetry for the superconducting state in some Fe-based materials. It is a common belief that a d-wave gap in the Fe-based superconductors must have nodes on the Fermi surfaces centered at the Γ point of the Brillouin zone. Here we show that, while this is the ... Web1.1. d-wave vs s-wave There are two kinds of nodes where a superconducting gap goes to zero: those that are imposed by the symmetry of the pairing state, and those that are accidental, not imposed by any symmetry but the result of an anisotropic pairing interaction. In a d-wave state, of B 1g symmetry in a tetragonal structure, the gap goes to ... greedy translate spanish
