Non-Hermitian chiral anomalies

Abstract
The quantum conservation laws of chiral currents of non-Hermitian systems are not related to those in Hermitianized and anti-Hermitianized systems, as would be expected classically, due to novel anomalous terms that are shown in this paper. In addition, some physical consequences of the non-Hermitian anomaly using a Chern-Simons description of non-Hermitian Weyl semimetals are presented.
