Description
We solve the Wigner equation for massless spin-1/2 charged fermions near global
equilibrium. The Wigner function can be obtained order by order in the power
expansion of the vorticity and electromagnetic field. The Wigner function has been
derived up to the second order from which the non-dissipative charge currents and
the stress tensor can be obtained. The charge and energy densities and the pressure
have contributions from the vorticity and electromagnetic field at the second order.
The vector and axial Hall currents can be induced along the direction orthogonal to
the vorticity and electromagnetic field at the second order. We also find that the
trace anomaly emerges natually in renormalizing the stress tensor by including the
quantum correction from the electromagnetic field.
