Description
The experimental confirmation of the polarization of the Lambda hyperons observed in relativistic heavy ion collisions experiments [1] has renewed the interest in anomalous transport of fermions due to the spin-orbit coupling (e.g., through the chiral vortical effect [2]). Using a non-perturbative technique [3], exact expressions are derived for the thermal expectation values of the stress-energy tensor, charge current and (anomalous) axial current for the case of massless rigidly-rotating fermions at finite chemical potential [4]. Compared to the relativistic kinetic theory analogue, the quantum corrections are expressed as constitutive equations in terms of local kinematic quantities, such as the vorticity and acceleration.
