dc.descriptionThere are strong recent indications that the Kondo phenomena play important role in the electronic transport and dephasing mechanism for some of the experimentally investigated metallic samples. The spin and the orbital Kondo problem with two-level systems provide very similar behavior above the Kondo temperature. Below the Kondo temperature the behavior is drastically different as in the latter case the entropy remains non zero. In the following several results derived earlier by different methods are simply reproduced by the time-ordered diagram technique in the leading logarithmic approximation valid above the Kondo temperature.
