Solution of the Two-Channel Anderson Impurity Model - Implications for the Heavy Fermion UBe -
C. J. Bolech, N. Andrei
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 he…

Optical Conductivity and Pseudo-Momentum Conservation in Anisotropic Fermi Liquids
A. Rosch, N. Andrei
Umklapp scattering determines the conductivity of clean metals. In typical quasi one-dimensional Fermi liquids with an open Fermi surface, certain pseudo-momenta do not decay by 2-…
