Stokes Phenomena between AdS/CFT and dS/CFT

Masazumi Honda, Kotaro Shinmyo

As parameters are varied, the set of saddle points contributing to a (path) integral may change discontinuously, leading to a corresponding change in the asymptotic expansion of th…

de Sitter holography from a Lorentzian torus

Kosei Fujiki, Michitaka Kohara, Javier Moreno +2

We show that the quantum entanglement between the conformal field theories (CFTs) living on the future and past boundaries in the de Sitter/conformal field theory (dS/CFT) correspo…

More on Bulk Local State Reconstruction in Flat/Carr CFT

Peng-Xiang Hao, Kotaro Shinmyo, Yu-ki Suzuki +1

We revisit and extend the construction of bulk local states in flat holography, focusing on the induced representation obtained from the flat limit of the AdS highest-weight condit…

Entropic Interpretation of Einstein Equation in dS/CFT

Kosei Fujiki, Michitaka Kohara, Kotaro Shinmyo +2

In this paper, we demonstrate that the first law of holographic pseudo-entropy, which is a non-Hermitian generalization of entanglement entropy in a two-dimensional conformal field…

Bulk Reconstruction of Scalar Excitations in Flat/CCFT and the Flat Limit from (A)dS/CFT

Peng-Xiang Hao, Kotaro Shinmyo, Yu-ki Suzuki +2

We explore the reconstruction of bulk local states in three-dimensional flat spacetime (Flat) using states from two-dimensional Carrollian conformal field theories (CCFT),…

Probing de Sitter Space Using CFT States

Kazuki Doi, Naoki Ogawa, Kotaro Shinmyo +2

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 fi…
