Topological transitions that induce a chirality imbalance in a deconfined quark-gluon plasma (QGP) generate an electromagnetic current in the direction of an external magnetic field. This remarkable phenomenon, the Chiral Magnetic Effect, has been observed in condensed matter systems. In heavy-ion collisions, an interesting question of phenomenological relevance is how the chiral imbalance generated persists through a fluctuating background of sphalerons in addition to other ``non-anomalous” interactions with the QGP. To address this question, we construct a relativistic chiral kinetic theory using a world-line formulation of quantum field theory. This permits an intuitive and elegant interpretation of chiral kinetic dynamics in terms of a supersymmetric world-line action for spinning, colored, Grassmanian point particles in external backgrounds. We outline how Berry’s phase arises in this framework, and how its effects can be clearly distinguished from those arising from the chiral anomaly. Finally, we discuss the applications of our framework to discuss the transport of chiral fermions in other many-body contexts.
