Webrenormalizable and unitary. If the classical symmetry of the Lagrangian cannot be main-tained in the process of quantization, the theory is said to have an anomaly. Anomaly originated from the research on the decay of the neutral pion which can be well understood by chiral anomaly (Adler-Bell-Jackiw anomaly [1, 2]). The chiral anomalies have ... WebIn summary, inversion symmetry alone gives us $\mathbb Z_2$ topology. Particle-hole symmetry. The last symmetry we consider is actually a combination of previous symmetries, particle-hole symmetry for this problem will be the anti-unitary symmetry made by combining time-reversal symmetry and chiral symmetry. In fact, for this problem
