A Half de Sitter Holography
Taishi Kawamoto, Shan-Ming Ruan, Yu-ki Suzuki +1
A long-standing and intriguing question is: does the holographic principle apply to cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein a ti…
SVD Entanglement Entropy
Arthur J. Parzygnat, Tadashi Takayanagi, Yusuke Taki +1
In this paper, we introduce a new quantity called SVD entanglement entropy. This is a generalization of entanglement entropy in that it depends on two different states, as in pre-…
Gluing AdS/CFT
Taishi Kawamoto, Shan-Ming Ruan, Tadashi Takayanagi
In this paper, we investigate gluing together two Anti-de Sitter (AdS) geometries along a timelike brane, which corresponds to coupling two brane field theories (BFTs) through grav…
Timelike entanglement entropy
Kazuki Doi, Jonathan Harper, Ali Mollabashi +2
We define a new complex-valued measure of information called the timelike entanglement entropy (EE) which in the boundary theory can be viewed as a Wick rotation that changes a spa…
AdS/BCFT with Brane-Localized Scalar Field
Hiroki Kanda, Masahide Sato, Yu-ki Suzuki +2
In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds with bo…
Pseudo Entropy in dS/CFT and Time-like Entanglement Entropy
Kazuki Doi, Jonathan Harper, Ali Mollabashi +2
We study holographic entanglement entropy in dS/CFT and introduce time-like entanglement entropy in CFTs. Both of them take complex values in general and are related with each othe…
