The effect of hybridization on Kondo temperature and resistivity of some heavy fermion systems

Representing the heavy fermion systems by the Periodic Anderson Model (PAM), we have used Zubarev technique to study the temperature dependence of resistivity. The resistivity calculated shows the general features experimentally observed in these materials. Further, we have shown how the strength of hybridization as well as the position of the f-level affects the electrical resistivity and Kondo temperature of these systems.
