The subject of quantum optics involves interaction of optical radiation and matter withthe ultimate goal of observing and controlling non-trivial quantum dynamics. This iscommonly achieved in systems of, e.g., dilute atomic ensembles. The fundamentalquestion we are investigating is to what extent strongly interacting systems can becontrolled, both, in principle and in practice. The proposed project involves relatedaspects of three separate topics. The PI will investigate the build-up of cooperativebehavior such as superradiance and effects arising from it, specifically in the presenceof coherent fields and multiple levels. Secondly, she will study nonlinear coherentinteractions of light propagating in the presence of strongly interacting dipoles. She will,in particular, explore if such nonlinearities, mediated by molecular interactions, can beused to create coupling between single photons of the kind required for quantuminformation processing. A third part connects dipolar interactions with the properties ofquantum coherence based negative- refraction materials. For all three projects the PIwill concentrate on dipole-mediated interactions and nonlinearities.

量子光学涉及光辐射与物质的相互作用，其最终目的是观察和控制非平凡的量子动力学。这通常在系统中实现，例如，稀释的原子系综我们正在研究的基本问题是，在理论上和实践中，强相互作用系统能被控制到什么程度。拟议的项目涉及三个不同主题的相关方面。PI将研究合作行为的建立，如超辐射和由此产生的效应，特别是在相干场和多能级的存在下。其次，她将研究在强相互作用偶极子存在下光传播的非线性相干相互作用。特别是，她将探索这种由分子相互作用介导的非线性是否可以用来在量子信息处理所需的单光子之间产生耦合。第三部分将偶极相互作用与基于量子相干的负折射材料的性质联系起来.对于所有三个项目，PI将集中在偶极介导的相互作用和非线性。
