Some aspects of entropic gravity in the presence of a noncommutative Schwarzschild-deSitter black hole
摘要：
研究了非对易Schwarzschild-deSitter黑洞中熵力方法的一些特征.在这种设置中，小尺度和大尺度之间存在相似性。在很短和很长的距离上有两个有限的截止点，其中力和能量图在这些尺度上突然停止。我们发现，存在的deSitter核心周围的起源，引起的非交换性，除了在大规模的标准deSitter背景可能会导致违反等效原理。最后，为了直接观察非对易量子涨落引起的短尺度引力的有限截止，我们导出了一个有效的引力常量。
英文摘要：
We study some features of entropic force approach in the presence of a noncommutative Schwarzschild-deSitter black hole. In this setup, there exists a similarity between the small and large scales. There are two finite cut-off in very short and long distances wherein the force and energy graph stop abruptly at those scales. We find that the existence of a deSitter core around the origin, induced by noncommutativity, in addition to a standard deSitter background at large scale may lead to a violation of the equivalence principle. Finally in order to directly observe the finite cut-off at short-scale gravity, caused by noncommutativity quantum fluctuations, we derive an effective gravitational constant.
