宇宙学霍金辐射(英文)

Cosmological Hawking radiation

黑洞的霍金辐射是一种重要的量子现象,是霍金在1974年首先发现的.研究用到了由Parikh和Wilczek首先提出的隧穿方法的变形-Hamilton-Jacobi隧穿方法,发现Friedmann-Robertson-Walker（FRW）时空的捕获面也存在温度,称之为宇宙学霍金辐射.另外讨论了霍金温度的意义;最后精确计算了标准宇宙学模型的霍金温度.

The radiation of black holes,first discovered by Hawking in 1974,is an important quantum phenomenon.In this paper,we make use of the tunneling method,which was first put forward by Parikh and Wilczek,however,we make a variation,the Hamilton-Jacobi tunneling method.We find that,similarly to the case of black holes,there is a temperature corresponding to the trapping horizon of the Friedmann-Robertson-Walker（FRW）space-time,which we dubbed as cosmological Hawking radiation.Furthermore,we discuss the meaning of the Hawking temperature.Finally,we consider the concordance model ΛCDM,and calculate the value of the Hawking temperature exactly.
