Abstract

Using an Anderson impurity description of the high-Tc superconductors, we study the character of the states closest to the Fermi level. In a kind of phase diagram involving the Cu d−d Coulomb interaction (U), the charge-transfer energy (Δ), and the hybridization (T), we show under which conditions the singlet, triplet, or delocalized ligand hole states are closest to the Fermi level. For reasonable values of T the lowest-energy hole states are local singles (1A1g) of primarily d9L character for U>Δ and local triples (3B1g) of primarily d8 character for U<Δ.
