Linking Entanglement and Discrete Anomaly
Ling-Yan Hung, Yong-Shi Wu, Yang Zhou
In Chern-Simons theory, there is a discrete one-form symmetry, whose symmetry group is isomorphic to the center of the gauge group. We study the 't Hooft anomaly associated to…

Some recent studies of the AdS/CFT correspondence for condensed matter systems involve the Fermi liquid theory as a boundary field theory. Adding B-flux to the boundary D-branes le…
