Fundamental Physics and Cosmology

拟议的研究集中在与暴胀宇宙相关的三个中心主题上。首先，PI将专注于永恒膨胀的宇宙的大尺度结构，并考虑暗能量是随机参数的模型，该参数在各个地方都是不同的。将对这些模型的观测结果进行研究，并与数据进行比较。其次，PI将继续系统地研究各种拓扑缺陷的形成、演变和观测特征，包括那些在“膜世界”场景中假设的缺陷。第三，PI将调查与永恒暴胀相关的新宇宙学范式的结果，并就这一主题出版一本畅销书。

The proposed research focuses on three central topics related to the inflationary universe. First, the PI will focus on the large scale structure of the eternally inflating universe and consider models where the dark energy is a stochastic parameter which varies from one place to another. The observational consequences of such models will be investigated and compared to data. Secondly the PI will continue a systematic investigation of the formation, evolution and observational signatures of various topological defects including those postulated in "braneworld" scenarios.Thirdly the PI will investigate the consequences of the new cosmological paradigm connected with eternal inflation and publish a popular book on the subject.
