Reflected Entropy is a bipartite correlation measure with a simple geometric
holographic dual, the minimal entanglement wedge cross section. This duality
further motivates the idea that spacetime emerges from entanglement. Further, it
illustrates the richness of the multipartite entanglement structure of
holographic systems. A particularly interesting feature that we focus on in this
talk is the phase transition between a connected and disconnected entanglement
wedge where the reflected entropy jumps discontinuously. We explain how this
phase transition is resolved in random tensor networks which serve as toy models
for holography. This argument based on the replica trick motivates a general
ansatz for the mechanism of the phase transition in AdS/CFT.
