Transformation of the Hubbard Hamiltonian to the t-J Hamiltonian using the Raleigh- Schrodinger Perturbation Expansion

EO Aiyohuyin, FO Ezomo, A Oni-Ojo

Abstract


The t-J model is deduced from the Hubbard model using Rayleigh-Schrodinger perturbation theory. The exchange is antiferromagnetic as found by other workers.
