  Chiral active fluids are known to have anomalous transport properties such as
the so-called odd viscosity. In this paper, we provide a microscopic mechanism
for how such anomalous transport coefficients can emerge. We construct an
Irving-Kirkwood-type stress tensor for chiral liquids and express the transport
coefficients in terms of orientation-averaged intermolecular forces and
distortions of the pair correlation function induced by a flow field. We then
show how anomalous transport properties can be expected naturally due to the
presence of a transverse component in the orientation-averaged intermolecular
forces and anomalous distortion modes of the pair correlation function between
chiral active particles. We anticipate that our work can provide a microscopic
framework to explain the transport properties of non-equilibrium chiral
systems.
