Pseudogap and Fermi arc in kappa-type organic superconductors

AbstractThe 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.
