Аннотация: An effective temperature-dependent scattering matrix for a localized subsystem is obtained in the periodic Anderson model by summing itinerant variables in the diagrammatic series of perturbation theory. The effective interaction that occurs in this case can lead to an antiferromagnetic phase, a superconducting phase, and the phase of coexisting superconductivity and antiferromagnetism observed in heavy-fermion intermetallic compounds. © 2015, Allerton Press, Inc.
