Type I superconductors (the ones people understand) happen because electrons pair up. The equal charges participate on the problem, but do not stop the electrons from pairing up. There is a lot of virtual particle exchange between them, but that's how forces happen. It's more correct to say that the crystal mechanically constrains the electrons into pairs than that the electrons pair with virtual particles. (IANAP, but this one topic I have studies a little.) |
