Abstract

In single-trace TT¯ holography, for the negative sign of the deformation, the geometries dual to high energy states consist of a singular UV wall that separates black strings in the IR from an asymptotically linear dilaton spacetime. In the hologram, the black strings amount to states in a symmetric product of TT¯ deformed CFT2, whose energy and momentum are split equally among the different blocks. The properties of this holographic duality have intriguing similarities with the proposed principles of de Sitter holography. In this note, the analogy between the two is presented. In particular, as the horizon location approaches the UV wall, one obtains a state of maximum finite entropy and infinite temperature. On the other hand, the bulk temperature of the geometry obtained in the limit is small. These properties are identical to those proposed in empty de Sitter holography.
