摘要：

We amend ab initio strongly correlated band structures by taking into account the band-tailing phenomenon in doped charge-transfer Mott-Hubbard insulators. We show that the photoemission from band tails accounts for sharp "quasiparticle" peaks, rapid loss of their intensities in some directions of the Brillouin zone ("Fermi arcs"), and high-energy "waterfall" anomalies as a consequence of matrix-element effects of disorder-localized states in the charge-transfer gap of doped cuprates.
