Abstract
We discuss the behavior of the two-channel Kondo model with channel an isotropic exchange couplings by using our recent solution of the model . This solution provides an analytic description of the interesting cr oss-over from a high-temperature regime, dominated by the non-Fermi-li quid behavior of the isotropic two-channel Kondo model, to a low-tempe rature regime characterized by the standard Fermi-liquid behavior of t he single-channel Kondo model.
