Probing Fundamental Physics with Cosmology

该研究计划的主要重点是利用宇宙学作为理解基础物理学要素的工具，如量子引力和真空的本质。同时，该项目将与新的精确宇宙学观测紧密相连，特别是开发约束早期宇宙宇宙学的技术，这些技术将立即适用于未来的高精度宇宙学测量。要承担的两个主要任务是暴胀的现象学及其与令人兴奋的新观测数据的联系，以及如何以非真空能量为基础的机制/方案来解释观测到的宇宙膨胀率的加速。该研究计划的一个核心内容是扩展和更新先前有关早期宇宙物理学的宇宙学观测工作，特别是暴胀。这将包括对资助期间发布的新数据集的分析，以及对未来实验的误差预测。该提案的项目包括：更新和扩大利用观测结果约束暴胀物理学的努力；开发和分发用于搜索或表征膨胀参数空间的新数字代码；进一步研究移植效应；研究非暴胀的早期宇宙模型。

The primary focus of the proposed research project is to use cosmology as a tool for understanding elements of fundamental physics such as quantum gravity and the nature of the vacuum. At the same time, the proposed project will be firmly connected to new precision cosmological observations, in particular developing techniques for constraining early universe cosmology which will be immediately applicable to future high-precision cosmological measurements. The two major tasks to be undertaken are the phenomenology of inflation and its connection to the exciting new observational data and how non vacuum energy-based mechanisms/schemes could account for the observed acceleration of the expansion rate of the universe. A central element of the proposed research program is to extend and update previous work relating cosmological observations to the physics of the early universe, especially inflation. This will involve analysis of new data sets released during the period covered by the grant, and error forecasting for future experiments. The projects of this proposal include: updating and expanding efforts to constrain inflationary physics using observational results; developing and distributing new numerical codes for searching or characterizing inflation parameter space; investigating further transplanckian effects; and investigating alternate, non-inflationary early universe models.
