Probing de Sitter space using CFT states
Abstract In this paper we construct CFT states describing a putative holographic dual to local excitations in the three-dimensional de Sitter space (dS), called the bulk local states. We find that the conjugation operation in dS3/CFT2 is notably different from that in AdS3/CFT2. This requires us to...

| description | Abstract In this paper we construct CFT states describing a putative holographic dual to local excitations in the three-dimensional de Sitter space (dS), called the bulk local states. We find that the conjugation operation in dS3/CFT2 is notably different from that in AdS3/CFT2. This requires us to combine two bulk local states constructed out of different primary states in a CPT-invariant way. This analysis explains why Green’s functions in the dS Euclidean vacuum cannot simply be obtained from the Wick rotation of those in AdS. We also argue that this characteristic feature explains the emergence of a time coordinate from the dual Euclidean CFT. We show that the information metric for the quantum estimation of bulk coordinate values replicates the de Sitter space metric. |
