项目摘要

This project will study quantum fluctuations of energy density and of gravity and related physical effects. Recent work has shown that the probability of very large energy density fluctuations is much larger than had previously been thought. These energy density fluctuations can also lead to large fluctuations of the gravitational field, which are a type of quantum gravity effect. This project will seek a deeper understanding of these large fluctuations. It will also study similar effects in condensed matter and atomic systems which may be possible to observe in the laboratory. The results of this investigation may have broader impacts on other areas of science, mathematics, and possibly technology. The basic principles and techniques to be explored are expected to have application beyond the specific set of topics to be studied. The project will contribute to education, and to human resource development through the involvement of students. Both graduate and undergraduate students can participate in various aspects of the project, and to improve their skills in scientific analysis and communication. The project will also create examples that will be useful to explain subtle concepts in quantum theory and gravity to students at various educational levels and to the general public.A better understanding of large energy density fluctuations and related effects are expected to lead to a deeper understanding both of quantum physics and of gravity. The effects on the gravitational field are quantum gravity effects, and their study can be one of the paths to a more complete quantum theory of gravity. This project will explore quantum fluctuations of nonlinear operators such as the quantum stress energy tensor. Of particular interest is the possibility of producing primordial black holes in the early universe this way.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.

该项目将研究能量密度和重力和相关物理效应的量子波动。最近的工作表明，非常大的能量密度波动的可能性比以前认为的要大得多。这些能量密度波动也可能导致重力场的大波动，这是一种量子重力效应。该项目将寻求对这些大波动的更深入的了解。它还将研究在凝结物质和原子系统中的类似效果，这些影响可能在实验室中观察到。这项调查的结果可能会对其他科学，数学和可能的技术产生更大的影响。预计要探索的基本原理和技术将超出要研究的特定主题之外的应用。该项目将通过学生的参与来为教育和人力资源开发做出贡献。研究生和本科生都可以参与项目的各个方面，并提高他们在科学分析和沟通方面的技能。该项目还将创建示例，这些示例将有助于解释量子理论中的微妙概念和对各种教育水平和公众的重力的微妙概念。对大型能量密度波动和相关效果的更好理解有望使您深入了解量子物理和重力。对重力场的影响是量子重力效应，它们的研究可能是通往更完整的重力理论的途径之一。该项目将探索非线性算子（例如量子应力能量张量）的量子波动。特别令人感兴趣的是，这种方式可能在早期的宇宙中生产原始的黑洞。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
