Description:
Author(s): Akira Oguri and A. C. Hewson We study the low-energy behavior of the vertex function of a single Anderson impurity away from half filling for finite magnetic fields, using the Ward identities with careful consideration of the antisymmetry and analytic properties. The asymptotic form of the vertex function Γ σ σ ′ ; σ ′ σ ( i ω , i ω ′ ; i ω ′ , i ω ... [Phys. Rev. B 97, 045406] Published Thu Jan 04, 2018
