Green's-function method for canonical ensembles. II. Response-function calculations
Abstract
The calculation of response functions in the Green's-function method for canonical ensembles is illustrated. The example given is the evaluation of the susceptibility of a lattice of magnetic ions in the mean-field approximation. © 1971 The American Physical Society.
