涨落黑洞的霍金辐射

Hawking Radiation from Fluctuating Black Holes

Tomohiro Takahashi, Jiro Soda

摘要:

经典上,黑洞具有刚性的事件视界。但是,量子力学上,黑洞的事件视界由于量子涨落而变得模糊。研究了涨落黑洞中实标量场的霍金辐射。对于度规扰动,我们导出了黑洞背景下的二次作用量。然后,我们计算了标量场作用量中的立方相互作用项。利用这些结果,我们得到了在标量场与度规相互作用下的霍金辐射的谱。事实证明,由于度规的量子涨落,光谱偏离了普朗克光谱。

英文摘要:

Classically, black Holes have the rigid event horizon. However, quantum mechanically, the event horizon of black holes becomes fuzzy due to quantum fluctuations. We study Hawking radiation of a real scalar field from a fluctuating black hole. To quantize metric perturbations, we derive the quadratic action for those in the black hole background. Then, we calculate the cubic interaction terms in the action for the scalar field. Using these results, we obtain the spectrum of Hawking radiation in the presence of interaction between the scalar field and the metric. It turns out that the spectrum deviates from the Planck spectrum due to quantum fluctuations of the metric.
