Multichannel Kondo resonance causes non-Fermi liquid behavior in many systems, as nanostructured metallic quantum dots and metallic alloys. The Kondo effect occurs at low temperatures and its indicating parameter is the Kondo temperature T K . This p

We compute the temperature dependent magnetic susceptibility of the single-impurity, two-channel Anderson model with an alternative multi-step numerical renormalization-group transformation, previously applied only to the two-impurity single-channel

Em algumas ligas metálicas existem átomos magnéticos cercados por vários outros não magnéticos. Os primeiros são tão poucos que não interagem entre si. Os segundos são maioria e formam uma banda de condução. Nestas ligas é comum a ocorr

A generalized two-channel Anderson Hamiltonian is diagonalized via the numerical renormalization group. The spectrum shows non-Fermi liquid fixed point for isotropic channel hybridization and normal Fermi liquid for the anisotropic case.
