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…
