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…

Toward a Consistent Definition of Holographic Entanglement Entropy in de Sitter Space
Shan-Ming Ruan, Yu-ki Suzuki
We investigate a new definition of holographic entanglement entropy in the framework of static patch holography for de Sitter space. Using the replica trick and twist operator form…

Holographic Entanglement Entropy in the FLRW Universe
Toshifumi Noumi, Fumiya Sano, Yu-ki Suzuki
We compute a holographic entanglement entropy via Ryu--Takayanagi prescription in the three-dimensional Friedmann--Lemaître--Robertson--Walker universe. We consider two types of ho…
