# Spatial Structure of the Cooper Pair

@article{Kadin2005SpatialSO, title={Spatial Structure of the Cooper Pair}, author={Alan M. Kadin}, journal={Journal of Superconductivity and Novel Magnetism}, year={2005}, volume={20}, pages={285-292} }

The Cooper pair is generally analyzed in momentum space, but its real-space structure also follows directly from the Bardeen–Cooper–Schrieffer (BCS) theory. It is shown here that this leads to a spherically symmetrical quasi-atomic wavefunction, with an identical “onion-like" layered structure for each of the electrons constituting the Cooper pair, with charge layers ∼0.1 nm and radius ∼100 nm for a classic BCS superconductor. This charge modulation induces a corresponding charge modulation in…
