Instability of metals with respect to strong electron-phonon interaction
Emil A. Yuzbashyan, Boris L. Altshuler, Aniket Patra
We show that thermal equilibrium between conduction electrons and phonons becomes kinetically unstable when the renormalized electron-phonon coupling exceeds a certain threshold. W…
Bounds on in the Eliashberg theory of Superconductivity. III: Einstein phonons
Michael K. -H. Kiessling, Boris L. Altshuler, Emil A. Yuzbashyan
The dispersionless limit of the standard Eliashberg theory of superconductivity is studied. The effective electron-electron interactions are mediated by Einstein phonons of frequen…
Bounds on in the Eliashberg theory of Superconductivity. I: The -model
Michael K. -H. Kiessling, Boris L. Altshuler, Emil A. Yuzbashyan
Using the recent reformulation for the Eliashberg theory of superconductivity in terms of a classical interacting Bloch spin chain model, rigorous upper and lower bounds on the cri…
Bounds on in the Eliashberg theory of Superconductivity. II: Dispersive phonons
Michael K. -H. Kiessling, Boris L. Altshuler, Emil A. Yuzbashyan
The standard Eliashberg theory of superconductivity is studied, in which the effective electron-electron interactions are mediated by generally dispersive phonons, with Eliashberg…
