摘要：

We determine exactly the fixed point Hamiltonian of the one-dimensional multichannel Kondo-Heisenberg lattice model for any number of channels N greater than or equal to 2. It is found to belong to a new class of non-Fermi-liquid fixed points, different from the usual Luttinger or Luther-Emery liquids. The fixed point describes an anomalous singlet with nontrivial internal dynamics manifesting itself in unconventional order. We compute the correlation functions of the various conventional and composite order parameters of the system, and And that for N less than or equal to 4 the composite order parameters induce the dominant instabilities.
