Abstract
We show how to resolve coherent low-energy features embedded in a broad hig h-energy background by use of a fully self-consistent calculation for compo site particle operators. The method generalizes the formulation of Roth, wh ich linearizes the dynamics of composite operators at any energy scale. Sel f-consistent equations are derived and analyzed in the case of the single-i mpurity SU(N) Kondo model.
