量子隧穿中的de Sitter辐射

On de Sitter radiation via quantum tunneling

G. E. Volovik

摘要:

我们讨论了为什么隧道图像不一定导致霍金辐射从德西特视界。与事件视界的凝聚态类似物的经验表明,德西特真空对霍金辐射是稳定的。另一方面,浸没在德西特背景中的探测器将探测到看起来像热辐射的辐射,其有效温度是与宇宙视界相关的霍金温度的两倍。

英文摘要:

We discuss why the tunneling picture does not necessarily lead to Hawking radiation from the de Sitter horizon. The experience with the condensed matter analogs of event horizon suggests that the de Sitter vacuum is stable against the Hawking radiation. On the other hand the detector immersed into the de Sitter background will detect the radiation which looks as thermal with the effective temperature twice larger than the Hawking temperature associated with the cosmological horizon.
