Incipient band
WebRefs. 27 and 29 suggest that the incipient bands are SC and the sign of the order parameter on them is opposite to that on the Fermi surfaces, while Ref. 28 states that the sign of the order parameter on the incipient bands is the same as that on the Fermi surfaces. In addition, Ref. 43 claims no SC pairing on the incipient bands. Further- WebJan 13, 2024 · The upper band (Band 2) is assumed to have a heavier mass than the lower band (Band 1).
