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-…
Complex saddles of Chern-Simons gravity and dS/CFT correspondence
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We examine the black hole solutions of dS gravity by applying the explicit dS/CFT correspondence. The gravity theory is described by Chern-Simons theory with complex ga…
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…
Complex saddles of three-dimensional de Sitter gravity via holography
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We determine complex saddles of three-dimensional gravity with a positive cosmological constant by applying the recently proposed holography. It is sometimes useful to consider a c…
