Title: Noninvertible Gauss Law and Axions
 
Abstract: In the past years, the notion of global symmetry in quantum field theory has gone through a rapid evolution to include generalized symmetries generated by topological defects of higher codimensions and/or with noninvertible fusion algebras. A prototypical example of a generalized global symmetry is the electric 1-form symmetry in free Maxwell theory. An electric 1-form symmetry is a modern, symmetry-based way to describe the Gauss law. In this talk, we will consider axion-Maxwell theory, where the presence of the axion-photon coupling explicitly breaks the naïve electric 1-form symmetry, hence making the Gauss law anomalous. We will see that, however, the electric 1-form symmetry can be resurrected if we give up invertibility. The noninvertible electric 1-form symmetry leads to a modified version of the Gauss law, which we call the noninvertible Gauss law.
