Abstract

We study the Page curve for asymptotically flat eternal Schwarzschild black holes in four and higher spacetime dimensions. Before the Page time, the entanglement entropy grows linearly in time. After the Page time, the entanglement entropy of a given region outside the black hole is largely modified by the emergence of an island, which extends to the outer vicinity of the event horizon. As a result, it remains a constant value which reproduces the Bekenstein-Hawking entropy, consistent with the finiteness of the von Neumann entropy for an eternal black hole.

    • Thanks for the link. I find it very frustrating when pop science magazines refuse to link to the actual paper. I don't want to read their attempt to put what the paper says into layman's language; their attempts are usually way off. I want to read the actual paper. Edit: I was…
