The Role of Phonon Mechanism in Electron Coupling

TL;DR

This paper investigates the phonon-mediated electron coupling within a generalized Frolich model, exploring its relation to experimental isotope effects in high-temperature superconductors and its connection to BCS theory.

Contribution

It introduces a parameter for electron-spin-phonon interaction and analyzes its relation to experimental data and theoretical limits.

Findings

Identified a specific parameter for electron-spin-phonon interaction.

Linked the interaction parameter to isotope-effect experiments.

Showed the asymptotic transition to BCS theory.

Abstract

In this article in the framework of generalized Frolich model we consider electron-spin-phonon system. A parameter of electron-spin-phonon interaction is found. It is shown its interrelation with experiments on isotope-effect on high temperature superconductors and asymptotic transformation to BCS theory.
