A Kondo hole is the charge neutral substitution of a rare earth ion by a non-magnetic analog. We consider the interaction between two Kondo holes in a Kondo insulator described by the non-degenerate Anderson lattice with a nearest-neighbor tight-binding conduction band on a simple cubic lattice.

We have studied the one-dimensional Kondo chain at half-filling using a density matrix formulation of the numerical renormalization group. As the exchange coupling J --. 0, RKKY interactions become more important, and the correlation length and the staggered susceptibility x(q = 2kv) diverge.
