Research in Theoretical Cosmology, Gravity and Supergravity

该奖项支持在引力、基本粒子理论和宇宙学的界面上进行理论研究的计划。这些项目包括研究暗能量的伽利略模型，它似乎推动了宇宙的加速，使用宇宙学拓扑引力作为量子引力的理论实验室，发展了一个行为良好但只有两个空间维度的量子重力理论，可能会对更现实的理论产生影响，以及将贝尔-罗宾逊张量从广义相对论推广到其他引力理论。近年来，在测量从最大尺度到最小尺度的自然属性的能力方面取得了巨大进步，这给理论物理学带来了问题和挑战。两个主要的例子是理解暗物质和暗能量，它们似乎构成了当今宇宙的96%，并协调了爱因斯坦的广义相对论和量子力学的原理，前者似乎描述了宏观世界的引力，后者似乎统治着原子和基本粒子的微观世界。这项研究计划预计会对这两个问题产生影响。国际和平协会计划继续就这些主题撰写一系列教学文章。

This award supports a program of theoretical research at the interface of gravitation, elementary particle theory, and cosmology. Projects include the study of "Galileon" models of the dark energy that appears to drive the acceleration of the universe, the use of cosmological topological gravity as a theoretical laboratory for quantum gravity, the development of a well behaved theory of quantum gravity but with only two spatial dimensions that might have implications for more realistic theories, and generalization of the Bel-Robinson tensor from general relativity to other theories of gravity.The enormous improvements in recent years in the ability to measure the properties of nature from the largest to the smallest scales has raised questions and challenges for theoretical physics. Two major examples are to understand the dark matter and dark energy that appear to form 96% of today's universe and to reconcile Einstein's theory of general relativity that appears to describe gravity for the macroscopic world with the principles of quantum mechanics that appear to rule the microscopic world of atoms and elementary particles. This research program expects to have implications for both these questions. The PI plans to continue to write a series of pedagogical articles on these topics.
