Self-Consistent Modifications to the Electron Density of States due to the Electron-Phonon Interaction in Metals Several assumptions made in the standard theory of the electron-phonon interaction in metals, the Migdal theory, are questioned. The assumption of constant... F Dogan,F Marsiglio - APS...

For low energies, this is a direct measurement of the energy dependence of the electron-phonon interaction strength of electrons in a specific orbit on the Fermi surface. Also for higher energies effects of the anisotropy of the electron-phonon interaction are observed....
If the SO interaction is removed, the gap closes again in lead nanowires. The preservation of metallicity is very important in the GPT[3]. It is related to the presence of a mirror symmetry perpendicular to the wire axis, conserved by ...
Electron‐Phonon Interaction and Superconductivity in Metals A first principle derivation, in terms of electron‐ion pseudopotential and the phonon spectrum, is presented for the electron‐phonon coupling constant λ... SC Jain,CM Kachhava - 《Physica Status Solidi》 被引量: 0发表: 1980年 Electro...
For some time there has been considerable interest in the phonon anomalies in transition metals. A major stimulus for much of the present activity was the work of Varma and co-authors [1,2]. By a judicious separation of the total crystal energy, they isolated the long and short ranged ...
Optical sum rule in metals with strong electron-phonon interaction72.10.Bg74.25.Gz74.25.Kc74.72.-hThe properties of a superconductor featuring strong electron-phonon and electron-impurity interactions have been studied in a single-band approximation. It is shown that the elastic scattering of electrons...
Effects of interaction between metallic electrons and local phonons on physical properties are investigated. Distribution function of the local oscillator is calculated by the Monte Carlo method. The adiabatic potential becomes a double well when the interaction is sufficiently strong. It is shown that ...
