Derivation of the indirect interaction operator by the path integral method. Exact results in the $s-d$ exchange model
A. F. Izmailov, A. R. Kessel
Abstract:
A method of obtaining the effective Hamiltonian of indirect interaction is suggested which is based on the path integral method. The nonperturbative expression for the potential of two-particle indirect interaction of localized magnetic momenta is derived in the $s-d$ exchange model.
