We study radiation of a quantum deformed Schwarzschild black hole surrounded by a quintessence field, through a tunneling process. When the background spacetime of a black hole is covered by a scalar field, such as a quintessence field, metric of the black hole changes for a particular range of the mass. Then, the geometry of the Schwarzschild black hole with one black hole horizon converts to geometry with two horizons: a black hole horizon and a cosmological horizon. In the presence of the quintessence as a background field, we study the tunneling process for massless and massive particles and we obtain the temperature of the black hole. We calculate and compare particles' tunneling rate from both of the black hole horizon and the cosmological horizon. The obtained temperature is regular, radiation modes encompass correlations and there is the Planck scale remnant with the quintessence contents. As an important result, thermodynamics of the Schwarzschild black hole surrounded by the quintessence field has a significant difference in the range 23<wq<13 relative to the ordinary case. Also, the behavior of temperatures in our case becomes similar to the Schwarzschild de-Sitter black hole temperatures. Furthermore, we show that quantum correction of the black hole in an embrace of the quintessence field changes the location of horizons but the quintessence field is more effective in this change. Eventually, while the quantum correction prevents to reach the singularity at r=0 in the final stage of the evaporation of the quantum deformed Schwarzschild black hole surrounded by quintessence, there is a Planck scale remnant with quintessence content.

量子变形包围的量子变形Schwarzschild黑洞中无质量和大质量粒子的隧穿

我们通过隧穿过程研究了量子变形的Schwarzschild黑洞的辐射,该黑洞被一个典型场包围。当黑洞的背景时空被标量场(例如典型场)覆盖时,黑洞的度量会在特定质量范围内发生变化。然后,具有一个黑洞视界的Schwarzschild黑洞的几何将转换为具有两个视界的几何:黑洞视界和宇宙学视界。在典型现象作为背景场的情况下,我们研究了无质量和块状粒子的隧穿过程,并获得了黑洞的温度。我们从黑洞视界和宇宙学视界中计算并比较了粒子的隧穿速率。获得的温度是正常的,辐射模式包括相关性,并且有普朗克标度和典型成分含量。重要的结果是,被典型场包围的Schwarzschild黑洞的热力学在范围上有显着差异-23<wq<-1个3相对于普通情况。同样,在我们的案例中,温度的行为变得类似于Schwarzschild de-Sitter黑洞温度。此外,我们表明,对典型场的包围中的黑洞进行量子校正会改变视界的位置,但是典型场在这种变化中更有效。最终,尽管量子校正阻止了在[R=0 在量子变形的Schwarzschild黑洞被精粹包围的蒸发的最后阶段,存在一个具有精粹含量的普朗克标度残余物。
