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…
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…
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…
Pseudoentropy sum rule by analytical continuation of the superposition parameter
Wu-zhong Guo, Yao-zong Jiang, Jin Xu
In this paper, we establish a sum rule that connects the pseudoentropy and entanglement entropy of a superposition state. Through analytical continuation of the superposition param…
Parameter dependence of entanglement spectra in quantum field theories
Wu-zhong Guo, Jin Xu
In this paper, we explore the characteristics of reduced density matrix spectra in quantum field theories. Previous studies mainly focus on the function $\mathcal{P}(λ):=\sum_i δ(λ…
