Black hole singularity and timelike entanglement

Blog Article

Abstract We study timelike and conventional entanglement entropy as potential Kitchen Utensils probes of black hole singularities via the AdS/CFT correspondence.Using an analytically tractable example, we find characteristic behavior of holographic timelike entanglement entropy when the geometry involves a curvature singularity.We also observe interesting phenomena that, in some particular setups, holographic timelike and conventional entanglement AV Cable entropy are determined from multiple complex saddle points, which fall outside the assumptions of the Lewkowycz-Maldacena type argument.
