Prospects to attain room temperature superconductivity
X. H. Zheng, J. X. Zheng, D. G. Walmsley
With a generic model for the electron-phonon spectral density, two simple expressions are derived to estimate the transition temperature and gap-to-temperature ratio in conventiona…

Umklapp scattering of pairs in BCS superconductivity theory
X. H. Zheng, D. G. Walmsley
The BCS theory of superconductivity is extended to recognize pairing of electrons by both normal and umklapp scattering. Application of the variational approach shows that coexiste…

Umklapp scattering and electron pairing cutoff in BCS superconductors
X. H. Zheng, D. G. Walmsley
In a superconductor electrons form pairs for which the end states of normal and umklapp scattering may overlap. This cuts electron pairing off at a phonon frequency, , low com…
