Query: The Maxwell-Bloch Theory in Quantum Optics and the Kondo Model   In this letter, the problem of radiation in a fiber geometry interacting with
a two level atom is mapped onto the anisotropic Kondo model. Thermodynamical
and dynamical properties are then computed exploiting the integrability of this
latter system. We compute some correlation functions, decay rates and Lamb
shifts. In turn this leads to an analysis of the classical limit of the
anisotropic Kondo model.
