0443607BalasubramanianThis three-year award supports US-Dutch cooperative research on string theory and cosmological spacetimes involving Vijay Balasubramanian and J. de Boer at the University of Amsterdam, The Netherlands. The project will develop three inter-related issues: a) the physics of the cosmological constant and the origin of cosmology from string theory, b) the quantum mechanical origin and nature of gravitational thermodynamics and singularity resolution in cosmological and black hole settings, and c) how time-dependent universes are described in string theory. The Institute for Theoretical Physics at the University of Amsterdam is currently one of the premier institutions in Europe doing string theory. The Dutch team has strengths on aspects of unstable systems with open string tachyons, cosmological singularities in string theory, the physics of de Sitter space, AdS/CFT correspondence, the construction of a holographic dual description of Minkowski space, brane destabilization in highly curved backgrounds, and on conformal field theory, non-commutative superspace, and supersymmetric gauge theories. These strengths complement those of the US team.

这个为期三年的奖项支持荷兰阿姆斯特丹大学的Vijay Balasubramanian和J.de Boer在弦理论和宇宙时空方面的美国-荷兰合作研究。该项目将开发三个相互关联的问题：a)宇宙常数的物理学和来自弦理论的宇宙学的起源，b)在宇宙学和黑洞环境中引力热力学和奇点分辨的量子力学起源和性质，以及c)如何用弦理论描述依赖时间的宇宙。阿姆斯特丹大学理论物理研究所目前是欧洲从事弦理论研究的主要机构之一。荷兰团队在具有开弦快子的不稳定系统、弦理论中的宇宙学奇点、德西特空间的物理学、ADS/CFT对应、Minkowski空间的全息对偶描述的构造、高度弯曲背景中的膜失稳、保形场理论、非对易超空间和超对称规范理论等方面具有优势。这些优势与美国队的优势相辅相成。
