摘要：
An approach to the problem of single-occupancy constraint in the t-J model is presented. In order to project out the states of double occupied sites, the electronic self-energy is introduced in an effective Hamiltonian. The self-energy is derived by applying the self-consistent moment method to the Hubbard model with infinite on-site Coulomb repulsion.
