    Abstract

    摘要

    It has become increasingly clear that the key to understanding many fundamental questions in quantum field theories (QFTs) is encoded in the underlying structure of entanglement and causality. In this talk, I will discuss a particular direction along such a line: tracing the quantum information and causality origins of energy conditions in QFTs. In particular, I will discuss two approaches to prove the averaged null energy condition (ANEC), one from entanglement constraint and the other from causality constraint. Furthermore, I will discuss how, by combining both elements and consider causality probed by the entanglement data, one can prove the stronger quantum null energy condition (QNEC).
