This award is concerned with a broad range of research in gravitational physics. The specific research topics that will be investigated include the development of an axiomatic framework for quantum field theory in curved spacetime, the investigation of convergence issues in perturbative quantum field theory, the development of a gauge independent formulation of the effects of gravitational radiation reaction on point particles, the investigation of multiple lensing encounters and other issues in gravitational lensing, the investigation of fundamental issues related to inflation and dark energy, and the analysis of the viability of models with extra dimensions and theories that involve modifications to Einstein's equation. Although this research includes a wide range of topics in a number of different areas, there is a common theme to the main goals of the research: To obtain a deeper understanding of the mathematical and physical properties of classical general relativity and of quantum phenomena occurring in strong gravitational fields.Progress on the topics relating to quantum field theory in curved spacetime should have a significant impact on research in quantum gravity. The development of a gauge independent formulation of gravitational radiation reaction should signficantly aid the calculation of effects that may be observed by LIGO and LISA. Progress on gravitational lensing, issues related to inflation and dark energy, and models with extra dimensions should have a significant impact on research in cosmology. The general areas of research associated with this award are of considerable interest to the public. This award will heavily involve the direct participation of graduate students in all aspects of the research.

该奖项涉及引力物理学的广泛研究。具体的研究课题将包括弯曲时空中量子场论公理框架的发展，微扰量子场论收敛问题的研究，引力辐射反应对点粒子影响的规范独立公式的发展，多重引力透镜遭遇和引力透镜中其他问题的研究，调查与膨胀和暗能量有关的基本问题，分析具有额外维度的模型和涉及修改爱因斯坦方程的理论的可行性。虽然这项研究包括许多不同领域的广泛主题，但研究的主要目标有一个共同的主题：深入理解经典广义相对论的数学和物理性质以及强引力场中的量子现象。弯曲时空中量子场论的研究进展将对量子力学的研究产生重大影响。重力 引力辐射反应的规范无关公式的发展，应显着帮助计算可能被LIGO和丽莎观测到的影响。引力透镜、暴胀和暗能量相关问题以及额外维度模型的进展应该会对宇宙学研究产生重大影响。与该奖项相关的一般研究领域引起了公众的极大兴趣。该奖项将大量涉及研究生在研究的各个方面的直接参与。
