报告简介

　　The concept of pseudo entropy serves as a generalization of entanglement entropy, involving two distinct quantum states. In this talk, I will provide a brief overview of the definition of pseudo (Renyi) entropy and its computation in the context of quantum field theory. I will also introduce the constructible reality condition associated with pseudo entropy through the concept of pseudo-hermiticity. This condition can be associated with the structure of correlation function in QFTs. Additionally, the pseudo Renyi entropy can be linked to the Renyi entropy of the superposition of the two different states, giving rise to the sum rule for pseudo Renyi entropy. During the talk, I will present the proof of the operator sum rule and provide examples from both finite-dimensional systems and quantum field theory. The possible application and extension of the sum rule will be briefly mentioned. This talk is based on the works arXiv:2209.07308, 2206.11818, 2308.05261.
