Working within a specific technical setting known as cavity quantum electrodynamics, this project pursues a program of experimental and theoretical research aimed at elucidating the essential physics of the 'mesoscopic' transition regime that lies between the deeply quantum-mechanical behavior of individual atoms and the classical behavior of large ensembles of atoms. Our findings are of basic interest both for fundamental physics and for future engineering applications in nanotechnology, which often seeks to exploit unique aspects of mesoscopic physics. Our approach is to conduct new experiments using several tens of atoms in a setting in which we have previously characterized the behavior of individual atoms and of ensembles of thousands of atoms. We will pursue rigorous quantitative comparisons between experimental data and computer simulations based on fundamental theoretical models.The research crosses traditional boundaries between academic disciplines in science, engineering and mathematics. The graduate student working on the project receives unique interdisciplinary training and our research provides excellent source material for classroom teaching. The publications and research presentations based on this research can reach new audiences in engineering and applied mathematics who may commonly study some of the kinds of nonlinear dynamical behaviors that we are investigating, introducing them for the first time to novel quantum mechanical aspects that emerge in the mesoscopic, nanoscale regime.

该项目在称为腔量子电动力学的特定技术环境中工作，旨在通过实验和理论研究计划，旨在阐明“介绍”过渡方案的基本物理学，该物理是个人原子的深度量子力学行为与大型原子的经典经典行为之间的深度量子力学行为。 我们的发现对于基本物理和纳米技术中的未来工程应用都具有基本兴趣，这些技术通常试图利用中学物理的独特方面。 我们的方法是在我们以前已经表征单个原子和数千原子集合的行为的环境中使用几十原子进行新实验。 我们将基于基本理论模型进行实验数据和计算机模拟之间的严格定量比较。该研究跨越了科学，工程和数学学科之间的传统界限。 从事该项目的研究生接受了独特的跨学科培训，我们的研究为课堂教学提供了出色的原始材料。 基于这项研究的出版物和研究演讲可以吸引工程和应用数学的新受众，他们通常可以研究我们正在研究的某些非线性动力学行为，并首次将其引入新的量子机械方面，这些量子机械方面在中学，纳米级制度中会产生。
