Schwarzschild-de Sitter时空中的标量场涨落
Scalar field fluctuations in Schwarzschild-de Sitter space-time
摘要：
采用与暴胀宇宙中黑洞存在有关的平面坐标，计算了Schwarzschild-de Sitter时空中自由标量场的量子涨落。在微扰方法中，将小黑洞事件视界相对于de Sitter宇宙视界作幂次展开，得到了量子涨落的时间演化，进而导出了标量功率谱.
英文摘要：
We calculate quantum fluctuations of a free scalar field in the Schwarzschild-de Sitter space-time, adopting the planar coordinates that is pertinent to the presence of a black hole in an inflationary universe. In a perturbation approach, doing expansion in powers of a small black hole event horizon compared to the de Sitter cosmological horizon, we obtain time evolution of the quantum fluctuations and then derive the scalar power spectrum.
