Sr2CuO2Cl2. Signifies a virtually ideal circumstance of a two-D antiferromagnetic CuO2-aircraft and thus is of particular curiosity inside the context from the origins of high TC superconductivity. We use the single-website impurity Anderson product with 5 Cu 3d orbitals and O 2p valence bands specified because of the irreducible representations https://okada4dsg.com/
