Anisotropic optical response of dense quark matter under rotation -- compact stars as cosmic polarizers --    [PDF]

Yuji Hirono, Muneto Nitta

Quantum vortices in the color-flavor locked (CFL) phase of QCD have bosonic degrees of freedom localized on them, called the orientational zero modes. We show that the orientational zero modes are electromagnetically charged. As a result, a vortex in the CFL phase nontrivially interacts with photons. We show that a lattice of vortices acts as a polarizer of photons with wavelengths larger than some critical length.
