Quanta of Geometry

该奖项资助了黎巴嫩贝鲁特美国大学教授Ali Chamseddine的研究活动。近40年来，对基本物理相互作用的统一的追求一直是密集研究的主题。在这个程序中的绊脚石是将引力包括在其他三种力中，这些力协调着强相互作用、电磁相互作用和弱相互作用。后一种力在量子场论的框架内得到了很好的理解。相反，由于万有引力非常弱，只有宏观物体才有相当大的引力，因此人们主要只在经典水平上理解它。钱塞丁教授的研究重点是发展量子引力理论。因此，这一领域的研究推动了科学在其最基本的方向之一的进步：发现和理解新的物理定律。由于它的跨学科性质，这项工作也将有助于高能物理、引力物理、天体物理和宇宙学知识的发展。此外，预计该项目将产生更广泛的重大影响。贝鲁特美国大学(AUB)在推动美国在中东的教育体系方面发挥着非常重要的作用。最近启动的理论物理博士项目是促进中东高水平研究的一步，正在吸引高素质的学生。更严格地说，钱塞丁教授将在超重力、大统一模型、量子引力、弦理论和非对易几何方面进行研究。他将继续在非对易几何中构建谱流形，该几何复制了与重力耦合的标准拉格朗日模型。此外，他还将研究这种量子化方案的物理应用和动力学实现。

This award funds the research activities of Professor Ali Chamseddine at the American University of Beirut, Lebanon.The quest for unification of fundamental physical interactions has been the subject of intensive research for nearly forty years. The stumbling block in this program is the inclusion of the gravitational force among the other three forces mediating the strong, electromagnetic and weak interactions. These latter forces are very well understood in the framework of quantum field theory. In contrast, the gravitational force, because of its extreme weakness, is sizable only for macroscopic objects and is therefore mainly understood only at the classical level. Professor Chamseddine's research focuses on the development of a quantum theory of gravity. As such, research in this area promotes the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. Due to its interdisciplinary nature, this work will also contribute to the advancement of knowledge in high-energy physics, gravitational physics, astrophysics, and cosmology. Moreover, this project is envisioned to have significant broader impacts. The American University of Beirut (AUB) plays a very important role in promoting the American educational system in the Middle East. The recent launching of the Ph.D. program in theoretical physics is a step towards the promotion of high-level research in the Middle East, and is attracting students of high caliber.More technically, Professor Chamseddine will conduct research investigations in supergravity, grand unified models, quantum gravity, string theory and noncommutative geometry. He will pursue the construction of spectral manifolds in noncommutative geometry which reproduce the Standard Model Lagrangian coupled to gravity. In addition, he will study physical applications and dynamical realizations of this quantization scheme.
