论文摘要
早期的黑暗能量已成为解决哈勃张力的更有希望的方法之一 - 使用来自宇宙历史上不同时期的数据制成的哈勃常数测量之间的统计学意义差异。但是，从数据，诸如大规模结构张力以及理论上的问题（例如技术自然性和引入宇宙学中新的巧合问题）中产生的影响，并非没有其自身的挑战，无论是从数据而已。在此简短说明中，我在{\ IT第15届基本物理会议的第15个前沿进行了邀请的全体演讲}，我讨论了如何通过使用与宇宙学中已经存在的其他领域的耦合来改善一些早期黑暗能源的微调问题，而对于那些属于物质评估平等的上层已经是一个专业的，这是一个专业的界面。由此产生的模型 - 中微子协助了早期的暗能量和变色龙的早期黑暗能量 - 提供了可测试的，理论上可靠的实现这一总体想法。我将讨论这种方法的表述和宇宙学，包括观察和理论考虑所产生的一些限制。
Early dark energy has emerged as one of the more promising approaches to address the Hubble tension - the statistically significant disparity between measurements of the Hubble constant made using data from different epochs in cosmic history. However, the idea is not without its own set of challenges, both from the data, in the effects it has on other measurements, such as the large-scale structure tension, and from theoretical concerns such as technical naturalness and the introduction of a new coincidence problem in cosmology. In this brief note, delivered as an invited plenary lecture at the {\it 15th Frontiers of Fundamental Physics conference}, I discuss how some of the fine-tuning problems of early dark energy can be ameliorated by using couplings to other fields already present in cosmology, and for which the epoch of matter-radiation equality is already a special one. The resulting models - neutrino assisted early dark energy, and chameleon early dark energy - provide testable, theoretically robust implementations of this general idea. I will discuss the formulation and the cosmology of such approaches, including some constraints arising from both observational and theoretical considerations.
