Abstract
In order to study the critical behavior of heavy fermions near an antiferro magnetic quantum critical point, we apply the mean-field renormalization gr oup to a simplified analog of the Kondo lattice, the Kondo necklace. We obt ain the quantum critical point for different dimensions as well as the corr esponding critical lines, (C) 2001 Elsevier Science B.V. All rights reserve d.
