US-Netherlands Cooperative Research: String Theory and Cosmological Spacetimes

这个为期三年的奖项支持由荷兰阿姆斯特丹大学的Vijay Balasubramanian和J. de Boer参与的关于弦理论和宇宙学时空的美荷合作研究。该项目将发展三个相互关联的问题：a)宇宙常数的物理学和弦理论的宇宙学起源，b)引力热力学的量子力学起源和本质，以及宇宙学和黑洞设置中的奇点分辨率，以及c)弦理论如何描述与时间相关的宇宙。阿姆斯特丹大学的理论物理研究所目前是欧洲研究弦理论的主要机构之一。荷兰团队在开放弦速子的不稳定系统、弦理论中的宇宙奇点、德西特空间的物理学、AdS/CFT对应、闵可夫斯基空间的全息对偶描述的构建、高弯曲背景下的膜不稳定性、共形场论、非交换超空间和超对称规范理论等方面具有优势。这些优势补充了美国队的优势。

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.
