In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. [1][2] In …

750 Anomalies in Quantum Field Theory keep the presentation to be physically transparent and as si mple as possible, even at the price of some degree of rigor. The prototype of a quantum …

Anomalies are due to the emergence of central charges in the algebra of conserved quantities. In this case one can have classical anomalies if it is in the algebra of Poisson brackets, or …

A conformal anomaly, scale anomaly, trace anomaly or Weyl anomaly is an anomaly, i.e. a quantum phenomenon that breaks the conformal symmetry of the classical theory.

2022年4月5日 · We give a pedagogical introduction to quantum anomalies, how they are calculated using various methods, and why they are important in condensed matter theory. We …

Finite group symmetry (both internal and spacetime) can have an anomaly. These will have nothing to do with chiral fermions, or ultra-violet divergences in quantum field theory. There is …

There are at least two things that are called quantum anomalies in the context of 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 …
