Hydrodynamic manifestations of gravitational chiral anomaly

TL;DR

This paper explores how gravitational chiral anomalies lead to universal hydrodynamic effects, specifically the Kinematical Vortical Effect, independent of temperature and density, confirmed for massless spin-1/2 fermions.

Contribution

It provides a theoretical analysis linking gravitational chiral anomalies to universal hydrodynamic transport phenomena, verified for massless fermions.

Findings

Confirmation of the Kinematical Vortical Effect's independence from temperature and density

Derivation of the effect from gravitational chiral anomaly considerations

Application to massless fermions with spin 1/2

Abstract

The conservation of an axial current modified by the gravitational chiral anomaly implies the universal transport phenomenon (Kinematical Vortical Effect) dependent solely on medium vorticity and acceleration but not dependent explicitly on its temperature and density. This general analysis is verified for the case of massless fermions with spin 1/2.
