Fundamental Physics in Cosmology

弦理论和超引力对于我们理解物理宇宙的结构是不可或缺的。在这个项目中，学生将探索从这些想法衍生出来的模型的宇宙学结果。特别是，双场论的形式化允许人们以一种在t对偶下明显对称的方式来描述基本弦。由此产生的低能真空的宇宙学后果尚未得到充分探索。探索德西特空间如何从超重力和弦理论中获得能量也至关重要。这项研究需要高水平的数学专业知识和物理直觉，并有可能为世界一流的研究项目做出贡献。

String theory and supergravity are integral to our understanding the structure of thephysical universe. In this project, the student will explore cosmological consequences ofmodels that descend from these ideas. In particular, the double field theory formalismallows one to describe the fundamental string in a way that is manifestly symmetric underT duality. The cosmological consequences of the resulting low energy vacua have not yetbeen fully explored. The quest to understand how de Sitter space can energy from bothsupergravity and string theory are also of crucial importance. This research requires highlevels of mathematical expertise and physical intuition, and has the potential tocontribute to a world class research programme.
