Electron-phonon interactions and related physical properties of metals from linear-response theory

Abstract

Spectral distribution functions of electron-phonon interaction ${\alpha }^{2}F(\omega )$ obtained by ab initio linear--response calculations are used to describe various superconducting and transport properties in a number of elemental metals such as Al,Cu,Mo,Nb,Pb,Pd,Ta, and V. Their lattice dynamics and self-consistently screened electron-phonon coupling are evaluated within local density functional theory and using linear-muffin-tin -orbital basis set. We conclude that our method provides the description of electron-phonon interactions in tested materials with the accuracy 10%.
