Abstract

In the presence of rotation, gravity induces, even at zero temperature, a chiral vortical current. This current is interpreted as emerging from the gravitational Chern–Simons current. We argue that this gravitational Chern–Simons chiral vortical current may provide a novel universal microscopic mechanism behind the generation of collimated jets from rotating astrophysical compact sources.
