I need help with the forming of cooper pairs.
The Pauli Exclusion Principle states that two Indistinguishable electrons cannot occupy the same quantum level or state.
I know that if two electrons have different spins then they are distinguishable and as a consequence of the principle stated above they can occupy the same quantum level.
In the BCS theory they say they do have different spins so that it is possible for them to appear as if they are attracting, but my question is why do they have different spins?
I was thinking that energy from sound is quantitised as phonons and therefore as a metal ion vibrates in a crystal lattice, a phonon can change the spin of one electron, allowing two electrons to bond loosely together as they have the possibility of being in the same state.
Is this wrong???
I couldnt exactly understand what the textbook meant about electron-phonon-electron interactions that allow two electrons to form a cooper pair.
An electron emitting a phonon, where does that come from?
