论文摘要
渐近安全重力是量子重力的一种有效方法。重要的是要区分受渐近安全重力启发的修饰重力。在本文中，我们检查了Schwarzschild黑洞的改进版本附近的物质粒子动力学。我们假设，在渐近安全的重力方案的背景下，黑洞周围的环境物质本质上是等温的，并通过在临界点得出溶液来研究物质的球形积聚。对等温测试流体的状态参数的各种值的分析，即$ k = 1，〜1/2，〜1/3，〜1/4 $，显示了在渐近安全的黑洞上积聚的可能性。我们将吸积问题作为哈密顿动力学系统，并详细解释其相流，从而揭示了渐近安全的重力理论的有趣结果。
Asymptotically safe gravity is one effective approach to quantum gravity. It is important to differentiate the modified gravity inspired by asymptotically safe gravity. In this paper, we examine the matter particles dynamics near the improved version of Schwarzschild black hole. We assume that in the context of asymptotically safe gravity scenario the ambient matter surrounding the black hole is of isothermal in nature and investigate the spherical accretion of matter by deriving solutions at critical points. The analysis for the various values of the state parameter for isothermal test fluids, viz., $k=1,~1/2,~1/3,~1/4$ show the possibility of accretion onto asymptotically safe black hole. We formulate the accretion problem as Hamiltonian dynamical system and explain its phase flow in detail which reveals interesting results in asymptotically safe gravity theory.
