SUMMARY

The discussion centers on Cooper pairs in superconductors, specifically addressing the cancellation of spins and its implications for spin polarization. It confirms that the spins in a Cooper pair, which consist of one spin-up and one spin-down, result in a scalar particle that behaves similarly to the Higgs boson. This phenomenon contributes to the Meissner effect, where the photon acquires mass, preventing the electromagnetic field from penetrating the superconductor. Additionally, the conversation touches on exotic superconductors that exhibit triplet pairing, leading to a more complex ground state.

Does the cooper pairs spins (up and down) cancelling out have anything to do with anything? Is the current spin polarized in a superconductor?
 
Physics news on Phys.org
The spins in a cooper pair add to zero so you have a scaler particle that behaves a little like the higgs'. It gives mass to the photon stopping the electromagnetic field from penetrating the material. This is known as the Meissener effect.
 
I think there are some exotic superconductors with a triplet (parallel spins) instead of singlet pairing.
The properties of the ground state are then richer.
