广义不确定原理对渐近安全大气层吸积过程的影响

Impact of generalized uncertainty principle on the accretion process within the asymptotically safe ambiance

摘要:

在广义不确定原理(GUP)的框架下,研究了量子引力对变形Schwarzschild黑洞吸积的影响。与GUP相连的最小可测量长度修正了史瓦西黑洞,使其有能力适应量子引力的修正。我们着眼于潜在的临界点位置,并计算物质吸积的临界速度。利用GUP提出的最小可测长度猜想,确定了多变物质在事件视界的温度和总积分通量修正。我们注意到量子引力对吸积过程有重要的影响。另外,量子引力区域也维持着一个渐近安全的环境。

英文摘要:

We investigate the impact of quantum gravity on accretion onto a modified Schwarzschild black hole within the context of the generalized uncertainty principle (GUP). The minimal measurable length connected to GUP modifies the Schwarzschild black hole, giving it the capacity to accommodate the correction due to quantum gravity. We look at potential critical point locations and calculate the critical speed of the matter accreting. We determine the temperature and total integrated flux correction at the event horizon for the polytropic matter using the least measurable length conjecture offered by the GUP. We note that quantum gravity has a significant impact on the accretion process Additionally, the quantum gravity regime also maintains an asymptotically safe ambiance.
