Query: Odd Diffusivity of Chiral Random Motion   Diffusive transport is characterized by a diffusivity tensor which may, in
general, contain both a symmetric and an antisymmetric component. Although the
latter is often neglected, we derive Green-Kubo relations showing it to be a
general characteristic of random motion breaking time-reversal and parity
symmetries, as encountered in chiral active matter. In analogy with the odd
viscosity appearing in chiral active fluids, we term this component the odd
diffusivity. We show how odd diffusivity emerges in a chiral random walk model,
and demonstrate the applicability of the Green-Kubo relations through molecular
dynamics simulations of a passive tracer particle diffusing in a chiral active
bath.
