| 英文摘要 | We consider the symmetric single-impurity Anderson model in the presence of pairing fluctuations. In the isotropic limit, the degrees of freedom of the local impurity are separated into hybridizing and nonhybridizing modes. The self-energy for the hybridizing modes can be obtained exactly, leading to two subbands centered at +/- U/2. For the nonhybridizing modes, the second order perturbation yields a singular resonance of the marginal Fermi liquid form. By multiplicative renormalization, the self-energy is derived exactly, showing that the resonance is pinned at the Fermi level, while its strength is weakened by renormalization. |
