具有整体单极子的Barriola-Vilenkin黑洞的量子隧穿辐射

The radiation of global monopole Barriola-Vilenkin black hole as tunneling

  • 摘要: 利用量子隧穿辐射理论计算出具有整体单极子的Barriola-Vilenkin黑洞的热辐射谱,发现量子隧穿辐射谱与Bekenstein-Hawking熵有关,不再是严格的纯热谱,在忽略二次项时与已知的Hawking辐射结果完全一致,并用数值方法比较了两者差异.

     

    Abstract: Radiation spectrum of global monopole Barriola-Vilenkin black hole is studied,based on quantum tunneling method.The result shows that the tunneling rate of particles at the event horizon of the black hole is relevant to Bekenstein-Hawking entropy and the radiation spectrum is not strictly pure thermal.It’s the same to Hawking spectrum when the quadratic term is neglected.The difference between two methods is compared by numerical calculation.
