更多来自虫洞的量子噪音

More quantum noise from wormholes

Douglas Stanford

摘要:

为了使黑洞蒸发是幺正的,霍金辐射的朴素密度矩阵需要用一些伪随机噪声来修正。利用虫洞,半经典引力似乎描述了这种噪音的平均“真随机”理论。本文讨论了有物质引力理论中的虫洞。它们是依赖于物质场的少量反作用的经典解,它们与给出佩奇曲线的虫洞密切相关。

英文摘要:

For black hole evaporation to be unitary, the naive density matrix of Hawking radiation needs to be corrected with a sprinkling of pseudorandom "noise." Using wormholes, semiclassical gravity appears to describe an averaged "true random" theory of this noise. We discuss the wormholes in dilaton gravity theories with matter. They are classical solutions that depend on a small amount of backreaction from matter fields, and they are closely related to the wormholes that give the Page curve.
