Abstract

We present thought experiments to measure the Arnowitt–Deser–Misner EADM and Bondi–Sachs energy EBS of isolated systems in general relativity. The expression of EBS used in the protocol is likely to have other applications. In particular, it is well-suited to be promoted to an operator in non-perturbative loop quantum gravity.

广义相对论中孤立系统总能量的操作意义

我们介绍了测量广义相对论中孤立系统的阿诺维特-德瑟-米斯纳能量 EADM 和邦迪-萨克斯能量 EBS 的思想实验。协议中使用的 EBS 表达式可能还有其他应用。特别是，它非常适合提升为非微扰环量子引力中的算子。
