Possible Pairing Symmetry in the FeSe-Based Superconductors Determined by Quasiparticle Interference
Possible Pairing Symmetry in the FeSe-Based Superconductors Determined by Quasiparticle Interference
We study the momentum-integrated quasiparticle interference (QPI) in the FeSe-based superconductors. This method was recently proposed theoretically and has been applied to determine the pairing symmetry in these materials experimentally. Our findings suggest that, if the incipient bands and the superconducting (SC) pairing on them are taken into consideration, then …
