暗能量与暗物质:走向统一的标量场?

Dark Energy vs. Dark Matter: Towards a Unifying Scalar Field?

A. Arbey

摘要:

宇宙学的标准模型认为存在两种成分,“暗物质“和“暗能量“,它们决定了宇宙的命运。它们的性质仍在调查中,还没有直接证据证明它们的存在。存在着重新解释宇宙学观测结果的替代模型,例如通过用一种独特的暗成分--暗流体的存在来取代暗能量/暗物质假设,暗流体能够模拟这两种成分的行为。在快速回顾了对这种统一暗流体的宇宙学约束之后,我们将提出一个基于复标量场的暗流体模型,并讨论势的选择问题。

英文摘要:

The standard model of cosmology suggests the existence of two components, "dark matter" and "dark energy", which determine the fate of the Universe. Their nature is still under investigation, and no direct proof of their existences has emerged yet. There exist alternative models which reinterpret the cosmological observations, for example by replacing the dark energy/dark matter hypothesis by the existence of a unique dark component, the dark fluid, which is able to mimic the behaviour of both components. After a quick review of the cosmological constraints on this unifying dark fluid, we will present a model of dark fluid based on a complex scalar field and discuss the problem of the choice of the potential.
