Superconductivity and the Cuprates,copic theory of Bardeen, Cooper, and Schrieffer (BCS) was put forth in 1957. Despite the enormous success of this theory and its subsequent generalizations to cases where phonon dynamics could no longer be ignored, superconductivity in the more recently discovered cuprate superconductors seems to el

It is therefore desirable to probe observables like single-particle energies as functions of good quantum numbers like (crystal) momentum. This is precisely the kind of measurement afforded by Angle-Resolved Photoemission Spectroscopy (ARPES), one of the most i

Conclusions,oximately account for the experimentally observed critical temperatures and the energy and momentum dependence of the pairing interaction in the cuprates. Therefore, magnetic excitations are a plausible explanation for Cooper pairing in these materials.

We use data from angle-resolved photoemission spectroscopy (ARPES) to construct the required Green’s functions and spin susceptibilities. We find that spin fluctuations can yield superconducting critical temperatures of the order of 60–90 K, in agreement with experiments.
