Umklapp frustration and field-theoretic approach to superconductivity
XH Zheng, DG Walmsley
The formula of Gell-Mann and Low can be applied to both the Stark effect and superconductivity. The standard version of the field-theoretic approach fits the Stark effect, because…

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…
