Previously, it was shown that a superconducting state dominated by singlet dx 2− y 2
intraband pairs emerges from the fluctuation exchange approximation (FLEX) applied to a …

Using principles of the Fadeev-Lovelace-Watson multiple scattering expansion, a T-matrix
approximation is derived which coincides with the Galitskii-Feynman T matrix in the normal …

Stability of supercurrents and condensates in type I superconductors

P Lipavský, K Morawetz, B Šopík, M Männel - The European Physical …, 2014 - Springer
Excitations of Cooper pairs into non-condensed bound pairs are similar to excitations of true
bosons out of the Bose-Einstein condensate. Using the Landau criterion of superfluidity we …
