Chiral-Transport-Induced Collective Modes in Strong Magnetic Fields and Their Implications for Neutron Star Phenomenology

In this thesis, we study the collective modes induced by the chirality of elementary particles in magnetized media and their implications for neutron star phenomenology. We theoretically predict that the chiral magnetic wave can arise in quark matter inside neutron stars, resulting in the emergence of novel types of seismic oscillations and associated gravitational waves in the context of asteroseismology. We also investigate the response to dynamical electromagnetic fields and find that a dynamical screening, distinct from the conventional Landau damping, occurs due to the chiral anomaly.
