Description
We derive an exact expression of the spin entanglement of electrons in Cooper pairs in the momentum space based on the BCS model. By using the average concurrence as a parameter describing the entanglement, we show a close relationship between the phase transition of superconductivity and the spin entanglement of the Cooper pairs
