This CAREER award supports an experimental program to create and study exotic forms of matter by developing the enabling technology for the quantum manipulation of dipolar atoms. Ultracold gases of highly magnetic atoms, such as dysprosium, offer opportunities to explore strongly correlated matter in the presence of long-range interactions in a manner difficult to achieve in other experimental settings. Techniques will be developed to perform the first laser cooling and trapping---and subsequent confinement in optical lattices---of dysprosium. This achievement will lead to the investigation of exotic states of matter that, in several cases, underlie proposed descriptions of poorly understood, though technologically relevant, condensed matter materials that do not obey standard Fermi liquid theory. Specifically, investigation of the ground states of quantum liquid crystals using fermionic Dy, as well as explorations of the inhomogeneous phases predicted by the extended Bose-Hubbard (EBH) model, will be possible through the cooling of Dy to degeneracy. Looking beyond quantum liquid crystal and EBH physics, developing ultracold Dy technology will lead to the exploitation of both Dy's telecom qubit transition and Dy's colossal magnetic moment for the realization of telecom-band quantum information processing and the development of ultra-high sensitivity, high-resolution atom chip microscopy of exotic condensed matter systems.Complementing the research program is a plan to teach physics through everyday technology: Combining the theme of GPS technology with the technical expertise drawn from this research program, core physics principles will be taught to undergraduate physics majors and high school "teacher leaders" through the development of a laboratory module on atomic clocks. This module will serve three educational missions: contributing to the improvement of K-12 student achievement in science by training high school teacher leaders via the EnLiST NSF Math and Science Partnership (MSP) program at the University of Illinois at Urbana-Champaign; augmenting the PHYS 403 Modern Experimental Physics lab that introduces upper-level undergraduate physics majors to skills and topics required for cutting-edge careers in science and technology; and providing hands-on laboratory experience for participants in a Master's Science Teaching Program, an upcoming accreditation program for Illinois teachers provided by the Department of Physics.

这一职业奖支持一项实验计划，该计划通过开发偶极原子量子操纵的使能技术来创造和研究奇异形式的物质。具有高磁性原子的超冷气体，如镝，提供了在存在远程相互作用的情况下探索强关联物质的机会，这在其他实验环境中是难以实现的。将开发技术来执行第一次激光冷却和捕获-随后在光学晶格中-限制-镝。这一成果将导致对物质的奇异状态的研究，在一些情况下，这是对不符合标准费米液体理论的、尽管在技术上相关的、鲜为人知的凝聚态物质的拟议描述的基础。具体地说，利用费米子Dy研究量子液晶的基态，以及探索扩展的Bose-Hubbard(EBH)模型预测的非均匀相，将有可能通过Dy冷却到简并。展望量子液晶和EBH物理学，发展超冷Dy技术将导致利用Dy的电信量子比特跃迁和Dy的巨大磁矩来实现电信频段的量子信息处理，并开发超高灵敏度、高分辨率的奇异凝聚物质系统的原子芯片显微镜。完成研究计划的是一项通过日常技术教授物理的计划：将GPS技术的主题与该研究计划的技术专长相结合，通过开发原子钟实验模块，向大学物理专业的学生和高中“教师领袖”讲授核心物理原理。该模块将服务于三个教育任务：通过伊利诺伊大学香槟分校的Enlist NSF Math and Science Partnership(MSP)计划培训高中教师领袖，帮助提高K-12学生的科学成就；扩充PHYS 403现代实验物理实验室，向高水平的本科物理专业学生介绍在科学和技术领域从事尖端职业所需的技能和主题；以及为硕士科学教学计划的参与者提供实践实验室体验，该计划是即将由物理系为伊利诺伊州教师提供的认证计划。
