By considering the back-reaction of the spacetime through the spherically symmetric quantum fluctuations of the background metric, Kazakov and Solodukhin removed the singularity of the Schwarzschild black hole. This regular Schwarzschild black hole has a spherical central region with a radius of the order of the Planck length. On the other hand, due to the positively accelerating expansion of the Universe, it seems that there exists a universal repulsive force known as dark energy. In the framework of quantum field theories, the quintessence field is a candidate model for investigating and modeling dark energy. Accordingly, by taking into account the quintessential matter field in the background of the Schwarzschild black hole, Kiselev gained the metric of this black hole surrounded by quintessence. By combining these two above ideas, in this study, we consider the quantum-corrected Schwarzschild black hole surrounded by quintessence to investigate null and time-like geodesics structure. Generally, this study points out that black holes are quantum-gravitational objects. We will show that the accelerated expansion of the Universe, instead of dark energy, happens because of the presence of quantum effects in this setup. Also, due to the presence of the central Planck-size sphere, the regular black hole has been possessed a shifting over radial coordinate in its inner structure.

被精华包围的量子校正史瓦西黑洞的测地线结构

通过背景度量的球对称量子涨落考虑时空的反向反应,Kazakov 和 Solodukhin 消除了史瓦西黑洞的奇点。这个规则的史瓦西黑洞有一个球形中心区域,其半径约为普朗克长度。另一方面,由于宇宙的正加速膨胀,似乎存在着一种普遍排斥力,称为暗能量。在量子场论的框架中,精华场是研究和模拟暗能量的候选模型。因此,通过考虑史瓦西黑洞背景中的典型物质场,基塞列夫得到了这个被典型包围的黑洞的度量。通过结合以上两个想法,在这项研究中,我们考虑了被精髓包围的量子校正的史瓦西黑洞,以研究零和类时间的测地线结构。一般来说,这项研究指出黑洞是量子引力物体。我们将证明,宇宙的加速膨胀,而不是暗能量,是由于这种设置中存在量子效应而发生的。此外,由于中央普朗克大小球体的存在,常规黑洞在其内部结构中具有径向坐标偏移。由于这种设置中存在量子效应,而不是暗能量。此外,由于中央普朗克大小球体的存在,常规黑洞在其内部结构中具有径向坐标偏移。由于这种设置中存在量子效应,而不是暗能量。此外,由于中央普朗克大小球体的存在,常规黑洞在其内部结构中具有径向坐标偏移。
