大额外维与全息术

Large Extra Dimensions and Holography

Chao Cao, Yi-Xin Chen

摘要:

全息原理断言,系统的熵不能超过其普朗克单位的边界面积。然而,传统的量子场论无法描述这样的系统。在这封信中,我们假设存在大的$n$额外的维度,并提出了在这种情况下,紫外和红外截止之间的关系。我们发现,如果$n=2$,这种有效场论可以很好地描述全息系统。如果这些额外维度在未来的实验中被发现,将有助于证明全息原理的有效性。我们还讨论了宇宙学常数问题的影响。

英文摘要:

The holographic principle asserts that the entropy of a system cannot exceed its boundary area in Planck units. However, conventional quantum field theory fails to describe such systems. In this Letter, we assume the existence of large $n$ extra dimensions and propose a relationship between UV and IR cutoffs in this case. We find that if $n=2$, this effective field theory could be a good description of holographic systems. If these extra dimensions are detected in future experiments, it will help to prove the validity of the holographic principle. We also discuss implications for the cosmological constant problem.
