- Geometry from Entanglement in Double Trace States

Bulk coherent states produced by Euclidean CFT sources can be used to study how geometry arises from entanglement: when these states obey the Ryu-Takayanagi formula, the linearized Einstein equations hold in the bulk without assuming the complete AdS/CFT correspondence. However, the Faulkner-Lewkowycz-Maldacena bulk entanglement term that corrects the RT formula does not play a role in these previous studies, since to leading order coherent states have the same entanglement entropy as the vacuum. We study states CFT states created by Euclidean, bilocal, double trace sources, which produce bulk squeezed states. We consider possible modifications to RT and study divergences in the perturbative expansion that occur for certain choices of source. We work towards determining constraints on the bulk geometry and state that arise from requiring FLM, akin to the linearized Einstein equations that arose for coherent states.
