In superconductivity, Meissner effect describes the expulsion of magnetic field.

Could this be described as a breaking of the electromagnetic force in the way that the higgs field breaks electro-weak force?

Yes. In a superconductor the photon gains a mass due to this effect, similar to the Higgs effect in the electroweak case.
 

Thread 'Stability of persistent currents in superconductors regardless of temperature'

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
