Holographic entanglement negativity for disjoint subsystems in AdSd+1d+1/CFTd
Abstract
In this paper, we propose a construction to compute the holographic entanglement negativity (HEN) for bipartite mixed state configurations of two disjoint subsystems in higher-dimensional conformal field theories (CFTds) dual to bulk AdSd+1d+1 geometries. Our proposal follows from the corresponding AdS3/CFT2 scenario and involves an algebraic sum of the areas of bulk RT surfaces for certain combinations of subsystems. By utilizing our construction, we compute the HEN at the leading order through a perturbative expansion, for such bipartite mixed states of two disjoint subsystems with long rectangular strip geometries in CFTds dual to bulk pure AdSd+1d+1 geometries and AdSd+1d+1-Schwarzschild black holes.
