Abstract: Eternal asymptotically AdS black holes are dual to thermofield double states in the boundary CFT. It has long been known that black hole singularities have certain signatures in boundary thermal two-point functions related to null… read more here.

Abstract: We study timelike and conventional entanglement entropy as potential 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… read more here.

Abstract: In this paper, we examine quantum mechanical operators whose classical counterparts, that define the interior geometry, diverge at the black hole singularity. We, therefore, analyze the integrals determining the expectation values of those operators with… read more here.
