Four atom states Cu3d x 2 -y 2 , Cu4s, O a 2 p x are involved in a tight-binding model for the superconducting CuO 2 plane. The orthorhombic distortion is taken into account by the differences of Cu-O hopping amplitudes and single-site oxygen energies Ξ΅ a and Ξ΅ b of two oxygen positions in the eleme
