Macroscopic parity violating effects and 3He-A -: art. no. 025014

We discuss parity violating effects in relativistic quantum theory and their analogues in the effective field theory of superfluid He-3-A. A mixed axial-gravitational Chern-Simons term in the relativistic effective action and its condensed matter analogue are responsible for the chiral fermion flux along the rotation axis of the heat bath in a relativistic system and for the unusual Omega-odd dependence of the zero-temperature density of the normal component on the rotation velocity in He-3-A.
