Decorated ${\mathbb{Z}}_2$ Symmetry Defects and Their Time-Reversal Anomalies

Clay Cordova, Kantaro Ohmori, Shu-Heng Shao +1

We discuss an isomorphism between the possible anomalies of $(d+1)$-dimensional quantum field theories with ${\mathbb{Z}}_2$ unitary global symmetry, and those of $d$-dimensional q…
