RT Journal Article T1 Entanglement entropy in cubic gravitational theories A1 Cáceres, Elena A1 Castillo Vásquez, Rodrigo A1 Vilar López, Alejandro K1 AdS-CFT Correspondence K1 Gauge-gravity correspondence AB We derive the holographic entanglement entropy functional for a generic gravitational theory whose action contains terms up to cubic order in the Riemann tensor, and in any dimension. This is the simplest case for which the so-called splitting problem manifests itself, and we explicitly show that the two common splittings present in the literature — minimal and non-minimal — produce different functionals. We apply our results to the particular examples of a boundary disk and a boundary strip in a state dual to 4- dimensional Poincaré AdS in Einsteinian Cubic Gravity, obtaining the bulk entanglement surface for both functionals and finding that causal wedge inclusion is respected for both splittings and a wide range of values of the cubic coupling PB Springer YR 2021 FD 2021 LK http://hdl.handle.net/10347/26757 UL http://hdl.handle.net/10347/26757 LA eng NO J.
