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). |
