Anisotropic Optical Response of Dense Quark Matter under Rotation: Compact Stars as Cosmic Polarizers
Quantum vortices in the color-flavor locked (CFL) phase of QCD have bosonic
degrees of freedom, called the orientational zero modes, localized on them. 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.Comment: 8 pages, 1 figure; v2: published version in Phys. Rev. Let
Anomalous-hydrodynamic analysis of charge-dependent elliptic flow in heavy-ion collisions
Anomalous hydrodynamics is a low-energy effective theory that captures
effects of quantum anomalies. We develop a numerical code of anomalous
hydrodynamics and apply it to dynamics of heavy-ion collisions, where anomalous
transports are expected to occur. This is the first attempt to perform fully
non-linear numerical simulations of anomalous hydrodynamics. We discuss
implications of the simulations for possible experimental observations of
anomalous transport effects. From analyses of the charge-dependent elliptic
flow parameters () as a function of the net charge asymmetry ,
we find that the linear dependence of on
the net charge asymmetry cannot be regarded as a robust signal of
anomalous transports, contrary to previous studies. We, however, find that the
intercept is sensitive to anomalous transport
effects.Comment: 11 pages, 3 figures, v
