Theory of Photoemission from the Copper Oxide Material
arXiv:cond-mat/9708177 · doi:10.1103/PhysRevB.55.642
Abstract
A mean-field theory which satisfying the electron on-site local constraint in the relevant regime of density for the high temperature superconductors is developed. Within this approach, the electron spectral function, the electron dispersion, and the electron density of states of copper oxide materials are discussed, and the results are qualitative consistent with the numerical simulations.
