Question

What is the reason for chiral anomalies in condensed matter systems?

Answer 1

the reason of chiral anomalies in condensed matter systems as they are the part of solid they don't have to condensed with other matters.This is the main reason for chiral anomalies in condensed matter systems.

Answer 2

The reason is that things ("anomaly flow") happen "outside" the effective field theory. For example, in Weyl semimetal, the "anomalous" charge flow from one Weyl point to another is simply because these Weyl points are just corners of the same energy band and we decide to ignore that fact in the
