Holographic Carrollian conformal field theories pseudoentropy

Year: 2026

Type: article

Abstract: According to the flat/CCFT correspondence, Carrollian conformal field theories (CCFT) in d dimensions are dual to asymptotically flat spacetimes in d + 1 dimensions. In this paper, starting from the holographic interpretation of pseudoentropy in the (A) dS 3 / CFT 2 , we show that both extremal spacelike and timelike curves possess a well-defined flat-space limit. The length of these curves can be regarded as the real and imaginary parts of the pseudoentropy for the underlying field theory, where only the real part has been considered thus far. Our calculations can confirm that the entanglement entropy in the CCFTs is fundamentally pseudoentropy.
