Abstract
We have studied the one-dimensional Kondo chain at half-filling using a density matrix formulation of the numerical renormalization group. A s the exchange coupling J --> 0, RKKY interactions become more importa nt, and the correlation length and the staggered susceptibility chi(q = 2k(F)) diverge.
