We solve the two-channel Anderson impurity model using the Bethe-ansatz. We determine the ground state and derive the thermodynamics, obtaining the impurity entropy and specific heat over the full range of temperature. We show that the low-temperature physics is given by a line of fixed points describing a two-channel non-Fermi-liquid behavior in the integral valence regime associated with moment formation as well as in the mixed valence regime where no moment forms. We discuss the relevance…

The correspondence between an extended version of the two-channel Anderson model and a particular type of biresonant level model is established and it is shown how the model approaches a universal line of fixed points non-Fermi liquid in nature.
