| 英文摘要 | Using the slave-boson approach, we show that the boundary terms of the t-J model change the symmetry of the system from an ordinary Lie group into a quantum group. The novel property of fermion condensation and boson saturation is demonstrated below the critical concentration point of doping using quantum symmetry. After taking into account the novel phenomena, we obtain an antiferromagnetic correlation and small Fermi pockets centered around (+/-1/2 pi, +/-1/2 pi) at low doping which evolve into a large Fermi surface at high doping concentrations. |
