Barriola-Vilenkin黑洞Dirac场的广义Stefan-Boltzmann定律

Generalized Stenfan-Boltzmann law of the Dirac field of Barriola-Vilenkin black hole

利用薄膜模型研究Barriola-Vilenkin黑洞的热辐射,得到了黑洞的热辐射满足广义Stefan-Boltzmann定律的结论,导出的广义Stefan-Boltzmann系数不再是一个恒量,当截断距离以及薄膜厚度取定后,它是一个与黑洞视界附近的时空度规以及辐射粒子的径向平均泻流速率有关的比例系数.得到的Barriola-Vilenkin黑洞视界附近Dirac场的辐射能通量与薄层膜内辐射粒子的径向平均泻流速率成正比,与黑洞的质量平方成反比。

Using the thin film model of black hole,the thermal radiation laws of the Barriola-Vilenkin black hole are studied.We obtained the result that the thermal radiation of the black hole always satisfies the generalized Stenfan-Boltzmann law.The derived generalized Stenfan-Boltzmann coefficient is no longer a constant.When the cut-off distance and the thin film thickness are both fixed,it is a proportional coefficient related to the space-time metric near the event horizon and the average radial effusion velocity of the radiation particles in the thin film.The radiation energy flux of the Dirac field of the Barriola-Vilenkin black hole is proportional to the average radial effusion velocity of the radiation particles in the thin film,and inversely proportional to the square of the black hole mass.
