Chiral Cherenkov radiation in Quark Gluon Plasma and other chiral media

Chiral Cherenkov radiation is a particular type of radiation emitted by a charged fermion traversing chiral medium. Its most remarkable features—the resonant behavior at a certain emission angle and the circular polarization of the spectrum—depend on the parameters of the chiral anomaly in a particular material or matter. Chiral Cherenkov radiation can be used to investigate the chiral anomaly in such diverse media as the quark-gluon plasma, Weyl semimetals, and axionic dark matter. Unlike the Cherenkov radiation, the chiral Cherenkov radiation gives a major contribution to the particle collisional energy loss. I discuss both quantum and classical aspects of the chiral Cherenkov radiation and its phenomenological applications.
