暗相互作用与宇宙学微调
Dark Interactions and Cosmological Fine-Tuning
摘要：
为了解决所谓的符合问题，人们提出了包含暗物质和暗能量相互作用的宇宙学模型。人们研究了不同形式的耦合，但有人声称，观测数据似乎将它们（其中一些）缩小到非常接近$Λ$ CDM模型的程度，从而大大降低了它们首先处理问题的能力。暗能量的初始能量密度的微小性问题也是近年来宇宙学模型研究的一个目标。利用适度的一般耦合方案，本文的目的是统一这些不同的方法，并阐明这类模型是否有任何真正的观点，在抑制上述问题，困扰我们目前对宇宙的理解，在定量和明确的方式。
英文摘要：
Cosmological models involving an interaction between dark matter and dark energy have been proposed in order to solve the so-called coincidence problem. Different forms of coupling have been studied, but there have been claims that observational data seem to narrow (some of) them down to something annoyingly close to the $Λ$CDM model, thus greatly reducing their ability to deal with the problem in the first place. The smallness problem of the initial energy density of dark energy has also been a target of cosmological models in recent years. Making use of a moderately general coupling scheme, this paper aims to unite these different approaches and shed some light as to whether this class of models has any true perspective in suppressing the aforementioned issues that plague our current understanding of the universe, in a quantitative and unambiguous way.
