The antiferromagnetic (AFM) state in the three-band Hubbard model on a CuO 2 plane is studied by using both the variational Monte Carlo (VMC) method based on the Gutzwiller wave function and the Rice-Ueda type Gutzwiller approximation (GA). Near half-filling, the VMC energy is significantly improved
We investigate the three-band extended Hubbard model for the CuO 2 planes of high-temperature superconductors. We consider the limit of U = I on Cu atoms and we include the nearest-neighbor Coulomb repulsion between holes on 2p x,y orbitals of oxygen and holes on 3d x 2 Γy 2 or 3d 3z 2 Γr 2 orbitals
