“…In this article we demonstrate that the parity anomaly, a purely QFT object, which, however, exhibits nontrivial connections with the heat kernel techniques, can be useful at this point. Dynamical breakings of symmetries have been considered in various physical contexts using various mechanisms [13][14][15][16][17][18]. The parity anomaly, see [19,20], was introduced as a dynamical breaking of parity due to quantum corrections in theories of three-dimensional fermions, which interact with external gauge fields and which are parity-invariant at the classical level.…”
