The T-J model and superconductivity

MI Umo

Abstract


The t-J model written in terms of Hubbard operators is studied with a view to contributing to the search for the mechanism of high temperature superconductivity in the cuprates. The method of irreducible Green function is used to obtain the spectrum of quasiparticles excitation and d-wave pairing gap function.
