Non-invertible topological defects in 4-dimensional ${\mathbb{Z}}_2$ pure lattice gauge theory

Masataka Koide, Yuta Nagoya, Satoshi Yamaguchi

We explore topological defects in the 4-dimensional pure ${\mathbb{Z}}_2$ lattice gauge theory. This theory has 1-form ${\mathbb{Z}}_2$ center symmetry as well as the Kramers-Wannier…
