Constraints on the possible pairing symmetry of iron arsenide superconductors in a two-orbital model
Constraints on the possible pairing symmetry of iron arsenide superconductors in a two-orbital model
In this work, we establish a few exact identities through commutation of intraorbital and interorbital on-site pairings with a two-orbital model describing the FeAs-based superconductors. Applying the conclusion drawn from rigorous relation and physical interpretation, we give constraints on the possible symmetries of the superconducting pairing of the model. Hence …
