Natural sciences, Physical sciences, Physics A pair of electrons (or other fermions), of opposite spin, whose theorised behaviour is the basis of the BCS theory of superconductivity.
- The fundamental requirement for superconductivity is the existence of Cooper pairs.1991, Werner Buckel, Superconductivity: Fundamentals and Applications, Wiley, page 42:
- This is because a superconducting state is composed of extended Cooper pairs. A coherence length, #92;xi, describes the extension length of a Cooper pair over which the two quasiparticles remain bound as a pair.2000, Lynne Marie Merchant, Variation of the Superconductor Order Parameter in Quench-condensed Granular Films, University of California, page 8:

- This is a direct macroscopic manifestation of the presence of a condensate of Cooper pairs in a superconductor.2004, Ludovic Pricoupenko, Hélène Perrin, Maxim Olshanii, Quantum Gases in Low Dimensions, EDP Sciences, page 173:
