Response Theory of the Electron-Phonon Coupling

Small book cover: Response Theory of the Electron-Phonon Coupling

Response Theory of the Electron-Phonon Coupling
by

Publisher: arXiv
Number of pages: 169

Description:
This article presents a systematic theoretical enquiry concerning the conceptual foundations and the nature of phonon-mediated electron-electron interactions. Starting from the fundamental many-body Hamiltonian, we propose a simple scheme to decouple the electrons and nuclei of a crystalline solid via effective interactions.

In this text we give a self-contained introduction to symmetric spaces and their main characteristics. We take an algebraic approach; therefore it is not necessary to know almost anything about differential geometry to be able to follow the outline.
