Topological Interactions of Non-Abelian Vortices with Quasi-Particles in High Density QCD

Understand

Non-Abelian vortices are topologically stable objects in the color-flavor locked (CFL) phase of dense QCD.

• We derive a dual Lagrangian starting with the Ginzburg-Landau effective Lagrangian for the CFL phase, and obtain topological interactions of non-Abelian vortices with quasiparticles such as $U(1)_B$ Nambu-Goldstone bosons (phonons) and massive gluons.
• We find that the phonons couple to the translational zero modes of the vortices while the gluons couple to their orientational zero modes in the internal space.
