What two theory 's were united by the quantum field theory ?
Anomaly ( physics ) , a failure of a symmetry of a theory 's classical action Conformal anomaly , a quantum phenomenon that breaks the conformal symmetry of the classical theory Chiral anomaly , an anomalous nonconservation of a chiral current Gauge anomaly , the effect of quantum mechanics that invalidates the gauge symmetry of a quantum field theory Global anomaly , an anomaly in quantum physics Gravitational anomaly , an effect in quantum mechanics that invalidates the general covariance of some theories of general relativity Mixed anomaly , an effect in quantum mechanics Parity anomaly , an anomaly that is associated with parity Konishi anomaly , the violation of the conservation of the Noether current associated with certain transformations Anomalons , some odd particle interactions that are seen in some high - energy physics Anomalous skin effect , when electromagnetic fields penetrate into a metal by an amount comparable to , or much less than , the mean free path .
