We investigate the propagation of electromagnetic radiation in the magnetic
dual chiral density wave (MDCDW) phase of dense quark matter. Considering the
theory of low-energy fluctuations in this phase, we show how linearly polarized
photons reaching the MDCDW medium couple to the fluctuation field to produce
two hybridized modes of propagation that we call in analogy with similar
phenomenon in condensed matter physics axion polaritons, one of them being
gapless and the other gapped. The gapped mode’s gap is proportional to the
background magnetic field and inversely proportional to the amplitude of the
inhomogeneous condensate. The generation of axion polaritons can be traced back
to the presence of the chiral anomaly in the low-energy theory of the
fluctuations. Considering the Primakoff effect in the MDCDW medium, we argued
that axion polaritons can be generated inside quark stars bombarded by
energetic photons coming from gamma-ray bursts and point out that this
mechanism could serve to explain the missing pulsar paradox in the galaxy
center.
