Magnon-mediated pairing and isotope effect in iron-based superconductors
Within a minimal model for the iron-based superconductors in which itinerant electrons interact with a band of local moments, we derive a general conclusion for multiband superconductivity. In a multiband superconductor, due to the Adler theorem, the interband scattering dominates the intraband scattering at the long wavelength limit as long …
