WebDec 28, 2024 · Our findings suggest that, if the incipient bands and the superconducting (SC) pairing on them are taken into consideration, then the experimentally measured bound states and momentum-integrated QPI can be well fitted, even if the SC order parameter does not change sign on the Fermi surfaces. WebA band positioned in the vicinity of the Fermi level is often referred to as an "incipient band," which has attracted increased interest recently in the context of the iron-based …

Web(Band 2) is assumed to have a heavier mass than the lower band (Band 1). Since we are interested in the situation where Band 2 is incipient (see text), the chemical potential μ is tuned around the bottom of Band 2. on the intraband pairing in the case in which the chemical potential is set around the bottom of the incipient band. WebNov 29, 2016 · We studied the pairing mechanism of the heavily electron doped FeSe (HEDIS) systems, which commonly have one incipient hole band—a band top below the Fermi level by a finite energy distance ε b —at Γ point and ordinary electron bands at M points in Brillouin zone (BZ). We found that the system allows two degenerate … flashfire coatings
