Vaidya-Bonner-de Sitter时空中标量粒子的热辐射

Thermal Radiation of Scalar Particles in Vaidya-Bonner-de Sitter Space-time

在Vaidya-Bonner-de Sitter时空中，研究了黑洞的标量粒子的量子热辐射。采用共形平直方法，确定了黑洞内外视界和宇宙视界的准确位置，得到了黑洞外视界和宇宙视界的温度。通过解弯曲时空中的Klein-Gordon方程，获得标量粒子的热辐射谱，粒子在视界上的电势能起化学势的作用。当该黑洞电荷为零时，以上结果就是Vaidya-Schwarzschild-de Sitter的情况。

The quantum thermal radiation of scalar particles is studied in the Vaidya-Bonner-de Sitter space-time.The exact locations of the cosmological,outer and inner horizons of the black hole and the radiation temperatures of the first two horizons are determined by using conformal flat method.Near the two horizons,the thermal radiation spectra of scalar particles are obtained by solving the Klein-Gordon equation in curved space-time .It is shown that the electric potential energy of the particles in the horizons plays the role of the chemical potential.When the charge of the black hole is zero,the above results reduce to that of the Vaidya-Schwarzschild-de Sitter black hole.
