Fully compensated Kondo effect for a two-channel spin S = 1 impurity

摘要: We study the low-temperature properties of generalized Anderson impurity model in which two localized configurations, one with doublets and other a triplet, are mixed by degenerate conduction channels. By using numerical renormalization group noncrossing approximation, we analyze entropy, its spectral density, equilibrium conductance for several values parameters. Marked differences respect to conventional one-channel spin $s=1/2$ model, can be traced as hallmarks an $S=1$, found Kondo temperature, width position charge-transfer peak, temperature dependence conductance. Furthermore, rich effects single-ion magnetic anisotropy $D$ on behavior. In particular, shown before, large enough positive system behaves ``non-Landau'' Fermi liquid that cannot adiabatically connected noninteracting turning off interactions. For negative effect is strongly suppressed. While suitable description single Ni embedded O-doped Au chain, it generic $S=1$ channels might realized nanoscopic systems.
