报告摘要:

Pseudo-entropyis an interesting quantity with a simple gravity dual, which generalizesentanglement entropy such that it depends on both an initial and a final state.

In this talk we start with an introduction of this new quantity explaining itsbasic properties. Next we will study its gravity dual. Finally, we will presentrecent numerical results of this quantity in a free scalar field theory and ina spin system, which imply that pseudo entropy can serve as a new quantum orderparameter.

This talk is based on arXiv:2005.13801 and arXiv:2011.09648.
