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.

在一个特定的技术设置称为腔量子电动力学的工作，该项目追求的实验和理论研究计划，旨在阐明“介观”过渡制度之间的深刻的量子力学行为的单个原子和原子的大合奏的经典行为的基本物理。 我们的研究结果是基础物理和未来的工程应用在纳米技术，往往试图利用独特的方面介观物理的基本兴趣。 我们的方法是使用几十个原子进行新的实验，在这种实验中，我们以前已经描述了单个原子和数千个原子的集合的行为。 我们将在实验数据和基于基本理论模型的计算机模拟之间进行严格的定量比较。研究跨越了科学，工程和数学学科之间的传统界限。 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优秀的素材。 基于这项研究的出版物和研究报告可以接触到工程和应用数学领域的新受众，他们可能会共同研究我们正在研究的一些非线性动力学行为，并首次向他们介绍在介观，纳米级制度中出现的新量子力学方面。
