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…
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…
Comment on: "Comment on "Nonperturbative calculation of Born-Infeld effects on the Schrödinger spectrum of the hydrogen atom"" by M. N. Smolyakov
H. K. Carley, M. K. -H. Kiessling
This reply to Dr. Smolyakov's comment [2] on our PRL paper [1] was solicited by PRL on Nov. 17, 2021 and submitted to PRL on Nov. 30, 2021. Regretfully, the editors of PRL decided…
