Figure 4. Fermi surfaces and the single-particle spectral functions of the Hubbard model on an anisotropic triangular lattice at 30 K.

Figure 4

(a–c) Fermi surfaces in the first BZ of κ-Cl for 17% hole doping (a), half-filling (b) and 17% electron doping (c), determined by the largest spectral intensity at the Fermi energy. (d–f) Single-particle spectral functions for 17% hole doping (d), half-filling (e) and 17% electron doping (f). The Fermi energy is located at ω=0 and the parameter set of this model is t'/t=−0.8, U/t=7 and t=55 meV.
