英文摘要: Within the t-J model, we study the electronic properties of a doped antiferromagnet on a kagome lattice based on the framework of the self-consistent mean-field theory. At the half-filling, the spin-liquid ground-state energy per site of the kagome antiferromagnet is E-g/N(s)J = - 0.859, which is in very good agreement with the numerical estimates. Away from the half-filling, the electron phatoemission spectroscopy and density of states are discussed, and the results indicate that there is a gap in the normal state of the system.
