Theoretical and Numerical investigations in classical and quantum gravity

该奖项支持经典和量子广义相对论的几条研究路线，并具有共同的数值技术。特别的重点将包括从数值演化的爱因斯坦方程的约束条件被违反时获得的解决方案的稳定性，适合于数值模拟的一个二元系统的中子星星和黑洞的初始条件的研究，并实施一致的离散化方法量子引力。其中一些研究和通过这些研究开发的技术将使正在运行或正在研究的地基和天基引力波探测器能够准确模拟引力辐射的天体物理源。此外，一个完整的、一致的量子引力方法仍然是基础物理学中最重要的未解决问题之一。

This award supports several lines of investigation in classical and quantum general relativity with a common thread of numerical techniques. The particular focus will include the stability of the solution obtained from the numerical evolution of the Einstein equations when the constraints are violated, the study of initial conditions appropriate for numerical simulation of a binary system consisting of a neutron star and a black hole, and the implementation of a consistent discretization approach to quantum gravity. Some of these studies and the techniques developed through themwill allow accurate simulation of astrophysical sources of gravitational radiation for ground-based and space-based gravitational wave detectors now operating or under study. In addition, a complete, consistent approach to quantum gravity remains one of the most important unsolved problems in fundamental physics.
