论文摘要
拓扑顺序（远程纠缠）在现代冷凝物理物理学中起重要作用。在本文中，我们将证明四维黑洞也可以具有拓扑顺序，这表明拓扑纠缠熵是非零的。拓扑顺序的特性表明，大的差异性将充当对称性（而不是规格）在物理状态上的转化。更重要的是，远程纠缠将使霍金辐射变得纯净。
Topological order (long-range entanglement) play important role in modern condensed matter physics. In this paper, we will show that the four dimensional black hole can also have topological order, by showing that the topological entanglement entropy is non-zero. The properties of the topological order show that the large diffeomorphisms will act as symmetry (not gauge) transformation on the physical states. More importantly, the long-range entanglement will make the Hawking radiation pure.
