Kondo effect in a tomonaga-luttinger liquid

Summary form only given. Kondo effect of the magnetic impurity in a interacting one-dimensional (ID) electron system, i.e., Toinonaga-Luttinger liquid, is studied. This problem is relevant to the /spl pi/ - d system, where the /spl pi/ band constitutes the 1D electron system. By using the poor rnan's scaling method, it is found that the Kondo coupling flows to strong coupling regime not only for antiferromagnetic but also for ferromagnetic case. The impurity spin is completely screened in the ground state, and the fixed-point Hamiltonian is that of two disconnected semi-infinite Tomonaga-Luttinger liquids and a spin singlet. Low temperature properties are also discussed by analyzing the leading irrelevant operators.
