Slater perturbation theorem
WebSep 7, 2024 · A linked-diagram theorem is introduced that proves the size-consistency of the finite-temperature many-body perturbation theory at any order. General-order algorithms implementing the recursions establish the convergence of the perturbation series toward the finite-temperature full-configuration-interaction limit unless the series diverges. WebJun 4, 1998 · ABSTRACT In this modification of Slater’s cavity perturbation theorem the perturbed magnetic field is expressed as a Fourier series based on the unperturbed cavity modes.

In mathematics and electronics, Cavity perturbation theory describes methods for derivation of perturbation formulae for performance changes of a cavity resonator. These performance changes are assumed to be caused by either introduction of a small foreign object into the cavity, or a small deformation of its boundary. Various mathematical methods can be used to study the characteristics of cavities, which are important in the field of microwave sy… WebThe following sections are included: * Introduction. * Slater's Perturbation Theorem. * Implication of Slater's Perturbation Theorem and Its Intuitive Derivation. * Field …
