Webinar on Quark Matter and Relativistic Hydrodynamics

Abstract: 

In this talk, we review the topological properties and possible astrophysical consequences of a spatially inhomogeneous phase of quark matter, known as the Magnetic Dual Chiral Density Wave (MDCDW) phase, which can exist at intermediate baryon density in the presence of a magnetic field. Going beyond mean-field approximation, we show how linearly polarized electromagnetic waves penetrating the MDCDW medium can mix with the phonon fluctuations to give rise to two hybridized modes of propagation: a rotated photon and a massive axion polarization. The formation of axion polarization in the MDCDW core of a neutron star can add mass to the star via the Primakoff effect, eventually triggering the star collapse. This mechanism provides a possible solution to the missing pulsar problem in the galactic center.
