Abstract

Electrons near the Fermi surface in a superconductor, that is in a system which conducts with zero resistivity, interact to form correlated pairs. This idea was first suggested by Cooper [196] and since then the pairs are often called “Cooper pairs”. They are constructed from states in which the two electrons have zero total spin and equal and opposite linear momentum k and −k. As discussed in the previous chapter, the effective interaction between electrons is a result of the virtual emission of a phonon by one electron and its absorption by another. This interaction causes scattering of an electron pair from states (k, −k) to states (k′, −k′) with an amplitude V k′k which depends on the electron-phonon coupling and on the phonon spectrum.
