关于全息暗能量的一两点评论

A Comment or two on Holographic Dark Energy

A. J. M. Medved

摘要:

最近,研究某种受全息术启发的暗能量模型成为一种时尚。这些调查确实在解释经验数据方面取得了一些重大进展。然而,令人惊讶的是,很少有人考虑到概念问题,如所涉能源的组成和性质。在当前的话语中,我们试图通过一些思辨的但逻辑上自洽的论证来填补这一空白。我们的构造带着我们沿着一条从纠缠熵开始,到哈勃大小的奇异粒子气体结束的道路前进。此外,我们对暗能量的解释也暗示了宇宙巧合问题的自然解决方案。

英文摘要:

It has, quite recently, become fashionable to study a certain class of holographic-inspired models for the dark energy. These investigations have, indeed, managed to make some significant advances towards explaining the empirical data. Nonetheless, surprisingly little thought has been given to conceptual issues such as the composition and the very nature of the implicated energy source. In the current discourse, we attempt to fill this gap by the way of some speculative yet logically self-consistent arguments. Our construction takes us along a path that begins with an entanglement entropy and ends up at a Hubble-sized gas of exotic particles. Moreover, our interpretation of the dark energy turns out to be suggestive of a natural resolution to the cosmic-coincidence problem.
