Abstract

We investigate the duality in the Kondo model. Starting from the s-d model with the coupling constant JJ, the strong coupling model with the constant of 1/J is identified. The model shows the unitary limit of the conductance, G=2e2/hG=2 e^{2}/h at zero temperature. The perturbation theory of the model gives qualitative agreement with the results of numerical renormalization group and Bethe ansatz near T=TKT=T_{K}.
