The Effect of Nonmagnetic Doping on the d-Wave Heavy Fermion Superconductivity

In the present article, the use of slave-boson mean-field theory of the extended Anderson lattice model has been generalized to the Nambu space. The Green's functions of heavy fermion superconductors (HFS) have been obtained. The high sensitivity of the d-wave pairing HFS to the nonmagnetic impurities has been studied. The obtained results are in good agreement with the recent experiments on HFS.
