The study focuses on the ground-state entanglement of gapped domain walls between topologically ordered systems in two spatial dimensions, deriving a universal correction to the ground-state entanglement entropy based on the total quantum dimension of superselection sectors localized on the domain wall. This expression is derived from the entanglement bootstrap method proposed recently.
We study the ground-state entanglement of gapped domain walls between topologically ordered systems in two spatial dimensions. We derive a universal correction to the ground-state entanglement entropy, which is equal to the logarithm of the total quantum dimension of a set of superselection sectors localized on the domain wall. This expression is derived from the recently proposed entanglement bootstrap method.
