Description
Chiral matter exhibits a variety of intriguing anomalous transport phenomena that originate from the chiral anomaly. Prominent examples of such phenomena include the chiral magnetic effect and the chiral vortical effect. In the hydrodynamic regime, we demonstrate that in a chiral plasma subject to an external magnetic field, the chiral vortical effect can induce a new type of magnetohydrodynamic instability called the chiral magnetovortical instability [1]. Furthermore, a background rotation will significantly catalyze the chiral magnetovortical instability and make it occur more easily [2]. In particular, this gives rise to a rapid growth of low-frequency wave modes. These results reveal the helicity transport between chiral fermions and macroscopic helicities. Our findings suggest a variety of possible implications for chiral matters, like the quark-gluon plasma in heavy-ion collisions.
