【Abstract】 The antiferromagnetic and superconducting phase of Large U Hubbard modelhas been discussed by using the Zou-Anderson spinor-holon effective Hamiltonian. The RPA calculation shows that in Fermi liquid area (δt≥J) and at lowtemperature the Neel temperature decreases as dopping δ increases. The gapequations of antiferromgnetism and of supercond uctor are also given by solvingthe Gorkov equation.更多还原
