    • M. Ogata and H. Shiba: Phys. Rev. B 41 (1990) 2326. They discussed the momentum distribution function n(k) and spin correlation function S(k) of the Hubbard chain model by the perturbation calculation. They showed that these functions do not have a power-law singularity but instead have a logarithmic singularity.

    • note
    • If the convergence radius of the perturbation expansion is not zero, the electronic state of the system should be not "Luttinger-liguid" but "Fermi-liquid" in the weak coupling limit.
