A POSSIBLE MODEL FOR THE ANOMALOUS ELECTRICAL RESISTIVITY IN THE PERIODIC DENSE KONDO SYSTEM

A model Hamiltonian resulting from an extended Schrieffer-wolff transformation on the Anderson lattice Hamiltonian with f-electron hopping has been used to calculate the anomalous temperature dependence of the electrical resistivity in the Kondo lattice compounds (e.g., CeAl₃ and CeCu₆). The Green's functions for the conduction electron have been calculated by the equation of motion approach. The numerical calculated results of the electrical resistivity of CeCu₆ is consistent with the experimental data.
