论文摘要
我们回顾了量子标量场的纠缠熵的表述，从其时空的两点相关函数来看。我们讨论了这种公式在因果集理论中在各种环境中研究纠缠熵的应用。这些设置包括在平坦时空，安静的时空，无质量和大规模理论的各个维度中的因果钻石的洒水，多个不相交的区域以及非局部量子场理论。
We review a formulation of the entanglement entropy of a quantum scalar field in terms of its spacetime two-point correlation functions. We discuss applications of this formulation to studying entanglement entropy in various settings in causal set theory. These settings include sprinklings of causal diamonds in various dimensions in flat spacetime, de Sitter spacetime, massless and massive theories, multiple disjoint regions, and nonlocal quantum field theories.
