| dc.description | The physical origin of cuprate high-temperature superconductor pseudogaps remains debatable. We point out that the indication of such excitation is hidden in the usual expression for the quasiparticle energy. It can be realized on a suitable multiband spectrum with an interband pairing channel. The band components bearing the chemical potential manifest superconducting gaps. A band with the Fermi energy outside creates a pseudogap type excitation. The latter does not characterize the pairing strength. On a doping-driven spectral arrangement the nature of low-energy excitations changes with doping. The pseudogap appears as a precursor of the corresponding superconducting gap on the doping scale. The corresponding critical points on the phase diagram are determined by the doping-driven overlap dynamics of the bare gapped electron spectrum. | |
