Cooper Pairing Revisited
V. C. Aguilera-Navarro, M. Fortes, M. de Llano +1
We recall the fundamental fact that Cooper pairs defined without ignoring two- hole pairs along with two-particle ones leads to a purely imaginary pair energy when the problem is b…

Generalized Cooper pairing and Bose-Einstein condensation
V. C. Aguilera-Navarro, M. Fortes, M. de Llano
A Bethe-Salpeter treatment of Cooper pairs (CPs) based on an ideal Fermi gas (IFG) "sea"' yields the familiar negative-energy, two-particle bound-state if two-hole CPs are ignored,…
