Sr2CuO2Cl2. represents a nearly suitable circumstance of the 2-D antiferromagnetic CuO2-plane and thus is of certain desire during the context of the origins of large TC superconductivity. We use The one-website impurity Anderson model with 5 Cu 3d orbitals and O 2p valence bands specified by the irreducible representations of https://okada4dsg.com/
