This award supports research on the following aspects of string theory: (1)The astrophysics of compact objects in string theory including thepossibility of compact objects in string theory rotating faster than allowed by black holes in general relativity; (2) Testing the principles of holography, microstates of gravity, and gauge-gravity correspondence in the Godel universe model and in string cosmology in general ; (3) Investigations of noncritical M-theory, if defined in terms of a double-scaled nonrelativistic Fermi liquid in 2 + 1 dimensions, in order to understand the landscape of all vacua in string/M-theory and time-dependend solutions; (4) Systematic research of the interface between string theory and nonrelativistic condensed matter theory; (5) Analyzing tachyons in string theories and their relationship to the description of the decay of the nonsupersymmetric spacetimes to nothing.Results from this research program could have profound implications forbetter understanding of the fundamental theory of Nature and its possible relations to and implications for other theoretical and experimental areas of physics, and can be fully expected to have a broader impact on the wide scientific community as well as the general public. The research will be conducted in full collaboration with other members of the string and particle theory group at UC Berkeley, and its students and postdocs, in the context of the Berkeley Center for Theoretical Physics, and the Particle Theory group at Lawrence Berkeley National Laboratory.

该奖项支持弦理论以下方面的研究：（1）弦理论中致密物体的天体物理学，包括弦理论中致密物体旋转速度超过广义相对论中黑洞所允许的速度的可能性;（2）测试哥德尔宇宙模型和弦宇宙学中的全息原理、引力微观态和规范-引力对应;（3）非临界M理论的研究，如果用2 + 1维的双标度非相对论费米液体来定义的话，以便理解弦/M理论和含时解中所有真空的景观：（4）系统研究弦理论和非相对论凝聚态理论之间的接口;（五）分析弦理论中的快子及其与非超对称时空衰变到虚无的描述的关系。这项研究计划的结果可能对更好地理解自然的基本理论及其与其他理论和实验领域的可能关系和影响产生深远的影响。物理学，并完全可以预期对广大科学界以及公众产生更广泛的影响。这项研究将与加州大学伯克利分校的弦和粒子理论小组的其他成员及其学生和博士后充分合作，在伯克利理论物理中心和劳伦斯伯克利国家实验室的粒子理论小组的背景下进行。
