Stability Analysis of Superconductivity in -LaScH and its Experimental Reproducibility from La-Sc Alloys
Dmitrii V. Semenok, Ivan A. Troyan, Di Zhou +4
In this work, we analyze the feasibility of room-temperature superconductivity in the lanthanum-scandium hydride -LaScH. We demonstrate that the electro…
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…
