And Yes it is a big deal - lecture
There is magnetism lurking in the background despite the fact that they are not magnets
A superconductor breaks Muon symmetry but you don't see the phase, if I just have a piece of superconductor you don't see the phase. However if I take this two superconductors and put them together very close to create a Josephson Junction, then I will see the phase; because each one, there is going to be some phase difference between them, and that's what I'm going to see.
So it could be that if you take a gas and impose... except that now that this gas of electrons, now the superconductor, are in a particular solid, there is some other parameter that complies with the solid in which these electrons live. And therefore you can not have such a situation, there is a macroscopic other parameter for example....it has a direction... and this direction is a macroscopic direction associated with the whole phase. So you can not actually have one or the other mixing on a microscopic scale. You can have break down into microscopic domains, that's for sure.

Muon spin relaxation is a dynamic method to resolve the type of the pairing symmetry in superconductors.
