Sr2CuO2Cl2. Represents an almost excellent scenario of the two-D antiferromagnetic CuO2-aircraft and therefore is of unique fascination inside the context of the origins of high TC superconductivity. We use The one-site impurity Anderson model with 5 Cu 3d orbitals and O 2p valence bands specified with the irreducible representations in https://okada4dsg.com/
