Entanglement wedge cross section inequalities from replicated geometries

We generalize the constructions for the multipartite reflected entropy in order to construct spacetimes capable of representing multipartite entanglement wedge cross sections of differing party number as Ryu-Takayanagi surfaces on a single replicated geometry. We devise a general algorithm for such constructions for arbitrary party number and demonstrate how such methods can be used to derive novel inequalities constraining mulipartite entanglement wedge cross sections.

Automated summary

This study generalizes constructions for multipartite reflected entropy and devises a general algorithm for constructing multipartite entanglement wedge cross sections with varying party numbers. It shows how these methods can be used to derive novel inequalities constraining multipartite entanglement wedge cross sections.
