Duality of Ryu-Takayanagi surfaces inside and outside the horizon
Wu-zhong Guo, Jin Xu
We study the Ryu-Takayanagi (RT) surfaces associated with timelike subregions in static spacetimes with a horizon. It is possible to find the analytical continuation of the RT surf…

Entanglement measures for causally connected subregions and holography
XiangKun Gong, Wu-zhong Guo, Jin Xu
In this paper, we investigate entanglement for causally connected subregions and in quantum field theory and holography. Recent developments have established that a transit…

Imaginary part of timelike entanglement entropy
Wu-zhong Guo, Jin Xu
In this paper, we explore the imaginary part of the timelike entanglement entropy. In the context of field theory, it is more appropriate to obtain the timelike entanglement entrop…
