This project will involve theoretical research on several topics related to quantum theory and gravitation. There will be special emphasis on phenomena related to quantum fluctuations including the operational meaning of spacetime geometry fluctuations, the probability distribution of quantumstress tensor fluctuations, the role of stress tensor fluctuations in inflation, and selected aspects of the Casimir force. This project seeks to integrate studies of the quantum nature of the gravitational field with studies of fluctuating electromagnetic forces. It is hoped that this type of investigation will lead to a deeper understanding of both types of phenomena. This project is expected to have a broader impact through possible benefits to other fields of science, to education, and to technology. It will entail international collaborations, and hence help to forge links with researchers in other countries. The insights and techniques of this work may be useful outside of the specific subfields of physics being investigated. The project will further education through the training of graduate students and by the involvement of faculty at primarily teaching institutions. It should also produce examples which can be used to explain some of the concepts of quantum theory and relativity to students on a variety of educational levels. The work on Casimir forces may eventually be useful in nanotechnology where a better knowledge of Casimir forces is likely to become important for the construction of small scale devices.

该项目将涉及与量子理论和引力有关的几个主题的理论研究。将特别强调与量子波动有关的现象，包括时空几何波动的作战含义，量子压量张量波动的概率分布，通货膨胀中应力张量波动的作用以及Casimir力的选定方面的作用。该项目旨在将重力场量子性质的研究与电磁力波动的研究相结合。希望这种类型的调查能够深入了解两种现象。预计该项目将通过对其他科学，教育和技术领域的可能利益产生更大的影响。它将带来国际合作，因此有助于与其他国家的研究人员建立联系。这项工作的见解和技术可能在研究的特定子场之外有用。该项目将通过培训研究生的培训以及教师参与主要教学机构的进一步教育。它还应该产生可以用来解释量子理论的某些概念和对学生在各种教育水平上的相对论的概念。关于Casimir部队的工作最终可能在纳米技术中有用，在纳米技术中，对Casimir部队的更好了解对于构建小型设备可能很重要。
