What do you mean by electrons pairing in superconductors

Question

The cooper effect why doesn't this affect pauli`s

exclusion Principle

Answer 1

The electrons in a Cooper pair are not sitting on top of each other, but are highly correlated - they are treated as one unit as if they were bound together as they tunnel through the superconducting lattice.. Both electrons have opposite spin, so no QM principles are violated.

Answer 2

Electrons pair up with one another to form bosons. These pairs then collapse into a single quantum state via a process called Bose-Einstein condensation and this allows electric current to flow without resistance. It's believed thet the Phonons (minute vibrations of a crystal latice) allow electrons with opposite spins to pair up. It's been postulated that this is what occurs in conventional low-temperature superconductors. Hope this helps...I realize the answer is more on-point if you have some background in superconductivity, but it is valid across platforms as well.
