George C. Schatz of Northwestern University is supported by an award from the Chemical Theory, Models and Computational Methods program in the Division of Chemistry to develop theory and models that describe the transfer of energy between molecules that is mediated by metal nanoparticles (typically silver, gold or aluminum) that show strong optical absorption properties known as plasmon excitation. The theory builds from the past history of research on energy transfer, but here is adapted to problems at the leading edge of science, in which energy transfer can extend over distances from 10s of nm to mm, involves strong coupling where traditional perturbation theory approaches can break down, and where quantum effects provide opportunities for making fundamental changes to the energy transfer process. Energy transfer involving metal nanoparticles is important in emerging optical technologies, including topics related to optical switching, in the development of new types of optical devices, in single photon emitters, and in secure communications. Schatz will also study energy transfer and other properties associated with quantum light including the emission, absorption and energy transfer involving two entangled photons. The students and postdocs who work on this project include a significant number of women and minorities, and they will acquire unique skills that they can use to launch their own careers. In addition, there will be outreach to K-12 groups, undergraduate training, numerous seminars and workshops, and interactions with the public.The proposed work on energy transfer mediated by metal nanoparticles is a relatively new field where analytical theory based on quantum mechanics is essential. In addition to analytical theory, the research will pursue computational algorithms for using the theory, and applications of the theory to describe experiments done by experimental collaborators. The theory includes the description of: (1) donor-acceptor energy transfer near arrays of plasmonic nanoparticles where energy transfer can be mediated by optical modes of the lattice, and where issues of coherence and strong light-matter interactions can be tuned by controlling array structural parameters and emitter/absorber concentrations; (2) energy transfer mediated by individual or a few nanoparticles where Schatz will develop a full quantum electrodynamics formalism that incorporates plasmonic, excitonic and electromagnetic states on equal footing and which will provide the capability of describing quantum effects under circumstances where perturbation-theory based energy transfer theory breaks down; (3) energy transfer associated with quantum light that is coupled to entangled plasmons, including donor-acceptor energy transfer in which interference between the entangled photons modulates the rate. In addition, (4) Schatz will collaborate with several experimentalists in the field who are studying problems related to plasmon-mediated donor-acceptor energy transfer involving structures where the donor, acceptor and nanoparticles are organized via DNA structures, or that involve arrays with unique optical cavity features.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.

乔治C.西北大学的Schatz得到了化学系化学理论，模型和计算方法项目的支持，以开发理论和模型，描述由金属纳米颗粒（通常是银，金或铝）介导的分子之间的能量转移，这些纳米颗粒显示出强的光学吸收特性，称为等离子体激发。 该理论建立在过去的能量转移研究历史的基础上，但这里适用于科学前沿的问题，其中能量转移可以延伸到10纳米到毫米的距离，涉及强耦合，传统的微扰理论方法可以打破，量子效应提供了对能量转移过程进行根本性改变的机会。涉及金属纳米颗粒的能量转移在新兴光学技术中是重要的，包括与光学开关相关的主题，在新型光学器件的开发中，在单光子发射器中，以及在安全通信中。 沙茨还将研究与量子光相关的能量转移和其他性质，包括涉及两个纠缠光子的发射、吸收和能量转移。从事该项目的学生和博士后包括大量的妇女和少数民族，他们将获得独特的技能，可以用来启动自己的职业生涯。此外，还将向K-12团体，本科生培训，众多研讨会和讲习班以及与公众的互动进行宣传。拟议的工作对能量转移介导的金属纳米粒子是一个相对较新的领域，分析理论的基础上量子力学是必不可少的。除了分析理论之外，该研究还将追求使用该理论的计算算法，以及该理论的应用，以描述实验合作者所做的实验。 该理论包括以下描述：（1）等离子体纳米颗粒阵列附近的供体-受体能量转移，其中能量转移可以由晶格的光学模式介导，并且其中相干性和强光-物质相互作用的问题可以通过控制阵列结构参数和发射体/吸收体浓度来调节;（2）由单个或几个纳米颗粒介导的能量转移，其中Schatz将开发一个完整的量子电动力学形式，激子态和电磁态处于同等地位，并将提供在基于微扰理论的能量转移理论崩溃的情况下描述量子效应的能力;（3）与耦合到纠缠等离子体激元的量子光相关联的能量转移，包括其中纠缠光子之间的干涉调制速率的供体-受体能量转移。 此外，（4）Schatz将与该领域的几位实验学家合作，他们正在研究与等离子体介导的供体-受体能量转移相关的问题，这些问题涉及供体、受体和纳米颗粒通过DNA结构组织的结构，该奖项反映了NSF的法定使命，并通过使用基金会的知识产权进行评估，被认为值得支持。优点和更广泛的影响审查标准。
