Resumen:
We consider a system of Kondo impurities with an RKKY interaction J between them. Using the exact solution of the impurity and approximating the effect of J, we calculate the critical temperature Tc as a function of the Kondo exchange JK. The function Tc(JK) is quadratic for low JK but then decreases and vanishes at a quantum critical point (QCP). The approach is useful to calculate thermodynamic properties of Kondo systems out of the QCP.
