| 英文摘要 | The quasiparticle spectra of the Hubbard model on the anisotropic triangle lattice at half filling is studied using the cluster perturbation theory and applied to the organic superconductor kappa-(BEDT-TTF)(2)X. We find that a d(x2-y2)-wave-like pseudogap phase emerges in the intermediate-coupling regime. Near the critical line of the Mott insulating transition, the Fermi surface becomes segmented with a Fermi arc, due to the partial opening of the Mott gap along the Fermi surface. The pseudogap with the Fermi arc is shown to be a precursor to the Mott insulator. |
