项目摘要

This award funds the research activities of Professor Ali Chamseddine at the American University of Beirut.Theoretical elementary-particle physics research aims to develop a better understanding of the building blocks of nature and their fundamental interactions. This is done by searching for and building theoretical models which go beyond what is presently known and which could be tested by experiments or which satisfy stringent mathematical requirements. This forces researchers in this field to explore the frontiers of knowledge and invent new methods for their analysis of such theories. Thus, research in this area advances the national interest by promoting the progress of science in one of the most challenging directions requiring human ingenuity: finding the physical laws that govern the universe and its matter constituents ranging from cosmic to subatomic scales. As part of this project, Professor Chamseddine will invent new mathematics to reach this scientific goal. In particular, the research of Professor Chamseddine will continue to develop new geometry that describes the hidden structure of spacetime and helps to explain why nature behaves in the way in which it is observed. Professor Chamseddine will also study a modified model of Einstein's General Relativity which explains the origin of dark matter and helps to solve some long-standing problems such as removing singularities in cosmological models at the birth of the universe and for black holes. This work will also have an important broader impact. The American University of Beirut plays a very important role in promoting the American educational system in the Middle East. This grant will therefore help to sustain a world-class scientific research program within that part of the world.At the technical level, the research of Professor Chamseddine is aimed at developing consistent noncommutative geometric models at the quantum level. One important step is to identify quanta of geometry that could be used as building blocks of matter to construct four-dimensional manifolds and their noncommutative extension. In addition, the work of Professor Chamseddine on the newly developed mimetic gravity will be applied to solve some outstanding problems in cosmology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项资助贝鲁特美国大学的Ali Chamseddine教授的研究活动。理论基本粒子物理学研究旨在更好地了解自然的组成部分及其基本相互作用。这是通过寻找和建立理论模型，超越目前已知的，可以通过实验测试或满足严格的数学要求。这迫使该领域的研究人员探索知识的前沿，并发明新的方法来分析这些理论。因此，这一领域的研究通过促进科学在需要人类智慧的最具挑战性的方向之一的进步来促进国家利益：找到支配宇宙及其从宇宙到亚原子尺度的物质组成的物理定律。作为该项目的一部分，Chamseddine教授将发明新的数学来实现这一科学目标。特别是，Chamseddine教授的研究将继续发展新的几何学，描述时空的隐藏结构，并有助于解释为什么自然界以观察到的方式表现。 Chamseddine教授亦会研究爱因斯坦广义相对论的修正模型，解释暗物质的起源，并有助解决一些长期存在的问题，例如在宇宙诞生时消除宇宙模型中的奇点，以及黑洞。这项工作还将产生重要的广泛影响。贝鲁特美国大学在中东地区推广美国教育体系方面发挥着非常重要的作用。因此，这笔赠款将有助于维持世界上这一地区的世界级科学研究计划。在技术层面上，Chamseddine教授的研究旨在开发量子层面上的一致非对易几何模型。重要的一步是确定几何量子，它们可以作为物质的构建块来构建四维流形及其非对易扩展。此外，Chamseddine教授在新开发的模拟引力方面的工作将被应用于解决宇宙学中一些悬而未决的问题。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
