Quintessence黑洞的量子隧穿效应以及黑洞遗迹

The Quantum Tunneling Effect and the Black Hole Remnant of Quintessence Black Hole

天文观测发现了暗能量的存在,因此可以讨论暗能量所包围的静态球对称黑洞。运用了Parikh的量子隧穿模型,研究了Quintessence黑洞的量子隧穿过程以及黑洞遗迹问题。结果表明,在能量守恒的条件下,黑洞外视界和宇宙视界处的粒子出射率与Bekenstein-Hawking熵有关,辐射谱不再是严格的纯热谱。在考虑一级修正后得到具有对数项的粒子隧穿几率,并讨论了黑洞遗迹的存在的可能性。

In this paper,we investigate the tunneling effect and remnant problem of Quintessence black hole.Since the dark energy in the universe makes it possible for us to discuss the static spherically symmetric black hole surrounded by dark energy.With the use of Parikh′s model of quantum radiation as tunneling,we show that both the emission of the particle on the event horizon and on the cosmic horizon are related to the change of Bekenstein-Hawking entropy and the spectrum is not pure thermal.We also obtain the logarithmic correction of the particle tunneling probability by considering the first-order correction.Finally,we study the possibility of black hole remnant.
