The energy of scalar particles in a generalized spherical symmetric evaporating charged black hole

利用弯曲时空中标量粒子运动的Hamilton-Jacobin方程,研究广义球对称带电蒸发黑洞周围时空中标量粒子的能量,得到了粒子的能量不仅与粒子的质量有关,还与黑洞的时空结构及视界的变化率有关.给出了发生自发辐射的能量条件.

Using Hamilton-Jacobin equation of scalar particles in curve space-time ,the energy of scalar particles in a generalized spherical symmetric evaporating charged black hole spacetime is studied. We find that the energy of scalar particles is not only depends on the mass and angular momentum of which, but also is related to the structure of space-time and the variations of event horizon of black hole. The energy condition for the occurrence of the spontaneous radiation is obtained.
