Query: Anomalous current from covariant Wigner functions   We consider accelerated and rotating media of weakly interacting fermions in
local thermodynamic equilibrium. Kinetic properties of this media are described
by covariant Wigner function calculated on the basis of relativistic
distribution function of particles with spin. We obtain the formulae for axial
current beyond the approximation of smallness of thermal vorticity tensor and
chemical potential and calculate its divergence. In the massless limit higher
order terms in vorticity and chemical potential compensate each other with only
the low-order contributions surviving. It is shown, that axial current gets a
topological component along the 4-acceleration vector. The similarity between
different approaches to baryon polarisation is established.
