Abstract

Strongly Correlated Electrons Condensed Matter Physics
We determine exactly the fixed point Hamiltonian of the one dimensional multichannel Kondo-Heisenberg lattice model for any number of channels N>=2. An anomalous singlet with non trivial internal dynamics is generated. We compute the correlation functions of the various conventional and unconventional order parameters of the system and find that for N<=4 the composite order parameter induce the dominant instabilities.
