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…
CFT derivation of entanglement phase transition in pseudo entropy
Hiroki Kanda, Tadashi Takayanagi, Zixia Wei
In this paper, we discuss the entanglement phase transition of pseudo entropy in CFTs. We focus on the case where the in-state and the out-state are different boundary states relat…
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…
Multi-entropy and the Dihedral Measures at Quantum Critical Points
Jonathan Harper, Ali Mollabashi, Tadashi Takayanagi +1
The multi-entropy and dihedral measures are a class of tractable measures for multi-partite entanglement, which are labeled by the Rényi index (or replica number) as in the RÅ
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…
Brane Cosmology from AdS/BCFT
Kosei Fujiki, Hiroki Kanda, Michitaka Kohara +1
In this paper, we study the time-dependent dynamics of an end-of-the-world (EOW) brane in AdS with a scalar field localized on the brane. We mainly studied several aspects of holog…
