Inner Product of Closed Universe from Gravitational Path-integral
Masamichi Miyaji, Sunil Sake, Kotaro Shinmyo
We construct the Hilbert space of a closed universe of fixed topology in anti-de Sitter (AdS) and de Sitter (dS) Jackiw-Teitelboim (JT) gravity from the gravitational path integral…
Spin-1 Bulk Local States in AdS/CFT and Carrollian Holography
Peng-Xiang Hao, Kotaro Shinmyo, Kenta Suzuki +2
We construct the bulk local states of a massive spin-1 field in AdS/CFT and three-dimensional Carrollian holography. In AdS, covariance under the isometries that leave a bu…
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…
Pseudo entropy under joining local quenches
Kotaro Shinmyo, Tadashi Takayanagi, Kenya Tasuki
We compute the pseudo entropy in two-dimensional holographic and free Dirac fermion CFTs for excited states under joining local quenches. Our analysis reveals two of its characteri…
