Cooper Pairs Spin: Questions Answered

AI Thread Summary
Cooper pairs in superconductors exhibit spins that cancel each other out, resulting in a scalar particle behavior similar to the Higgs boson. This cancellation leads to the phenomenon where the photon acquires mass, preventing the electromagnetic field from penetrating the material, known as the Meissner effect. Spin polarization in superconductors is a key aspect of their behavior, with some exotic superconductors featuring triplet pairing with parallel spins. The ground state properties in these cases are more complex and varied. Understanding these spin dynamics is crucial for advancing superconductivity research.

Does the cooper pairs spins (up and down) cancelling out have anything to do with anything? Is the current spin polarized in a superconductor?

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.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
