Non-Abelian Superconductivity

We establish a non-Abelian superconductivity and a non-Abelian Meissner effect by constructing an effective field theory of superconductivity in which a genuine SU(2) gauge symmetry governs the dynamics. We show that the magnetic flux is quantized in the unit of $4\pi \mathrm{/}g$, not $2\pi \mathrm{/}g$, in the non-Abelian superconductor.
