Abstract

Chiral anomaly observed in the chiral superfluid 3He-A is the result of the combined effect of the real space and momentum space topologies. This effect incorporates several topological charges in the extended (k, r)- space, which is beyond the conventional chiral anomaly in the relativistic systems.
