Generating Functional for Electron-Phonon Systems from Functional Integrals with One-Sided Boundary Conditions.
Abstract
The generating functional of thermal Green funcitons are generated for an interacting electron-phonon system through the use of functional integrals in holomorphic representations (c numbers for phonons and Grassman numbers for electrons). These integrals are over paths obeying one sided boundary conditions at either 0 or beta=1/kT, and do not require normalization factors unlike previous derivations. The Matsubara perturbation formalism is recovered without using any results from the standard operator method.
