摘要: We report finite-cluster diagonalizations which clarify the role of apical oxygen orbitals and copper in ground-state electronic properties high-temperature superconductors. The hole density distribution spin - correlation functions are analysed as interoxygen hopping other parameters. main conclusion is that for universally accepted parameters planes, small levels doping no phonons, three-band Hamiltonian suffices to describe ground state inverse photoemission.
