Chapter 4 of Lectures on Generalized Global Symmetries discusses applications to various familiar systems: free electrodynamics, electrodynamics with charged matter, non-Abelian and discrete gauge theory in the continuum and on the lattice, and the Ising model in statistical physics. It describes how the phase structure of such models can be understood in terms of the realization of higher-form symmetries. It also proves a Goldstone theorem for higher-form symmetries.
