广义不确定原理与Hoenava-Lifshitz引力

Generalized uncertainty principle and Hořava-Lifshitz gravity

Yun Soo Myung

摘要:

本文探讨了广义不确定原理(GUP)与修正的Hohava-Lifshitz(HL)引力之间的联系。GUP密度函数可以用修正的Hokava-Lifshitz引力的重整化群的截断函数来代替。我们找到了GUP校正的引力子传播子,并将其与HL引力中的张量传播子进行比较。两者在性质上是相似的,但是在GUP修正的引力子传播子中,由Cotton张量引起的$p^5$项被忽略了。

英文摘要:

We explore a connection between generalized uncertainty principle (GUP) and modified Hořava-Lifshitz (HL) gravity. The GUP density function may be replaced by the cutoff function for the renormalization group of modified Hořava-Lifshitz gravity. We find the GUP-corrected graviton propagators and compare these with tensor propagators in the HL gravity. Two are qualitatively similar, but the $p^5$-term arisen from Cotton tensor is missed in the GUP-corrected graviton propagator.
