Webbanomaly appears on the DW worldvolume as a mixed Zd˜ 4-Z C 2 anomaly [4,5,13]. Owing to the 2d nature of Schwinger model, its axial version can be mapped to the charge-2 vector model studied in the rst part of the paper. The results there show that the DW inherits the bulk anomaly, which is saturated by the presence of two degenerate vacua ...

By reviewing the derivation of charge conservation with the semiclassical Boltzmann equation, we argue that chiral anomalies could emerge in (1+1) dimensions without Berry curvature corrections to the kinetic theory.
