Abstract

We investigate the thermodynamics of a Schwarzschild black hole, surrounded by the quintessence energy-matter in the linear and quadratic generalized uncertainty principle framework. Considering the variance in the position to be of the order of the event horizon radius and equating the variance in the momentum to the Hawking temperature of the black hole, we substitute these variances in the deformed algebra. From there we obtained the generalized uncertainty principle-modified black hole temperature and eventually the specific heat of the black hole. Then we calculate the critical as well as the remnant mass and obtain the entropy relation. We observe that the entropy relation includes the usual leading order ``\textit{area divided by four}" term, sub-leading logarithmic term, and higher order inverse of the area corrections. Finally, calculating the energy output as a function of time, we obtain the evaporation time of the black hole. The results show the dependence of the quintessence parameter on the thermodynamic quantities in the framework of linear and quadratic generalized uncertainty principle.
广义不确定性原理框架下被五芒星包围的施瓦兹柴尔德黑洞的热力学
我们在线性和二次广义不确定性原理框架内研究了被能量-物质精华包围的施瓦兹柴尔德黑洞的热力学。考虑到位置的方差是事件视界半径的数量级,并将动量的方差等同于黑洞的霍金温度,我们将这些方差代入变形代数中。由此,我们得到了广义不确定性原理修正后的黑洞温度,并最终得到了黑洞的具体热量。然后,我们计算临界质量和存在质量,并得到熵关系。我们观察到,熵关系包括通常的前导项、次前导对数项和高阶的反等校正。最后,通过计算能量输出与时间的函数关系,我们得到了黑洞的蒸发时间。结果表明,在线性和二次广义不确定性原理的框架下,五元参数与热力学量之间存在依赖关系。
