广义不确定原理与Friedmann方程

The Generalized Uncertainty Principle and the Friedmann equations

Barun Majumder

摘要:

广义不确定原理(GUP)影响普朗克尺度的动力学。因此,已知的物理方程预计将在非常高的能量范围内得到修改。最近的作者(Ali et al. 2009)提出了一个新的广义不确定原理(或GUP),其中包含普朗克长度的线性项。在这篇文章中,建议的GUP表示在一个更一般的形式和效果进行了研究的修改的弗里德曼方程的FRW宇宙。在中途,已知的熵-面积关系得到了一些新的修正项,其中的首阶项与面积的平方根成正比。

英文摘要:

The Generalized Uncertainty Principle (or GUP) affects the dynamics in Plank scale. So the known equations of physics are expected to get modified at that very high energy regime. Very recently authors in (Ali et al. 2009) proposed a new Generalized Uncertainty Principle (or GUP) with a linear term in Plank length. In this article, the proposed GUP is expressed in a more general form and the effect is studied for the modification of the Friedmann equations of the FRW universe. In the midway the known entropy-area relation get some new correction terms, the leading order term being proportional to square root of area.
