Defect entanglement entropy for superconformal monodromy defects

Q: What does this research mean for the field?

For co-dimension two superconformal monodromy defects, the universal part of the defect entanglement entropy is explicitly related to field theory data and does not necessarily decrease along a renormalisation group flow, contrasting with the behavior of the bulk theories. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

Abstract

A bstract We compute the defect entanglement entropy for co-dimension two superconformal monodromy defects in well known maximally symmetric holographic theories of various dimension. In each case we explicitly relate the universal part of the defect entanglement entropy to field theory data characterising the defect conformal field theory. We provide evidence that, unlike in the bulk theories in which the defects reside, the universal part of the defect entanglement entropy does not necessarily decrease along a renormalisation group flow.
