Non-invertible and higher-form symmetries in 2+1d lattice gauge theories

Yichul Choi, Yaman Sanghavi, Shu-Heng Shao +1

We explore exact generalized symmetries in the standard 2+1d lattice ${\mathbb{Z}}_2$ gauge theory coupled to the Ising model, and compare them with their continuum field theory coun…
