Spontaneous Magnetization through Non-Abelian Vortex Formation in Rotating Dense Quark Matter

Understand

When a color superconductor of high density QCD is rotating, superfluid vortices are inevitably created along the rotation axis.

• In the color-flavor locked phase realized at the asymptotically large chemical potential, there appear non-Abelian vortices carrying both circulations of superfluid and color magnetic fluxes.
• A family of solutions has a degeneracy characterized by the Nambu-Goldtone modes CP2, associated with the color-flavor locked symmetry spontaneously broken in the vicinity of the vortex.
• In this paper, we study electromagnetic coupling of the non-Abelian vortices and find that the degeneracy is removed with the induced effective potential.
