Electron pairing in the presence of incipient bands in iron-based superconductors


الملخص بالإنكليزية

Recent experiments on certain Fe-based superconductors have hinted at a role for paired electrons in incipient bands that are close to, but do not cross the Fermi level. Related theoretical works disagree on whether or not strong-coupling superconductivity is required to explain such effects, and whether a critical interaction strength exists. In this work, we consider vario
