This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Atomic, Molecular, and Optical (AMO) physics studies fundamental building blocks of functional matter, including atoms and their constituents, molecules, and light at the quantum level. AMO physics has been a cornerstone for modern science and technologies, particularly the emerging field of quantum information science and technology. This project aims to form a strategic partnership between the Department of Physics at Florida International University (FIU) and the JILA Physics Frontier Center (JILA PFC) in the JILA institute to promote and advance diversity and research excellence in AMO physics at both institutions. The research goals will be achieved through two major research thrusts (ultra-cold atomic physics and single-molecule biophysics) that are designed to leverage the world-class experts at JILA PFC as well as the existing research capabilities at FIU. The project will improve the recruitment, retainment, and degree attainment of graduate students from underrepresented groups in both institutions by implementing PREP pathway improvement strategies. This partnership will advance research in AMO physics and improve the diversity of graduate students in both institutions. The proposed FIU-JILA partnership will conduct research in two major thrusts to advance AMO physics, particularly in understanding (1) many-body physics in ultra-cold atom arrays and (2) single-molecule biophysics. In thrust 1, the investigators will use femtosecond laser-based ultrafast spectroscopy to study many-body effects including interactions, correlations, and collective effects in atom arrays for applications in fundamental many-body physics and quantum technologies. They will also use femtosecond pulses to realize ultrafast manipulation of quantum states in atom arrays. In thrust 2, state-of-the-art single-molecule imaging and measurement techniques including confocal and total internal reflection microscopy, the integration of nanopipette-based electrochemical techniques with the single-molecule fluorescence techniques, the atomic force microscopy-based high-precision single-molecule force techniques, and molecular dynamics simulations will be developed and used to study folding kinetics and dynamics of biomolecules and intracellular single-molecule delivery and detection. The partnership will also improve the diversity of physics graduate students in both FIU and JILA by implementing PREP pathway improvement strategies including faculty/student exchange visits, engaging undergraduate students in summer research at JILA PFC, engaging undergraduate and graduate students in proposed research activities at FIU, student mentoring, and public lectures at the Phillip and Patricia Frost Museum of Science in Miami.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.

该奖项的全部或部分资金根据《2021 年美国救援计划法案》（公法 117-2）提供。原子、分子和光学 (AMO) 物理学研究功能物质的基本组成部分，包括量子水平上的原子及其成分、分子和光。 AMO物理一直是现代科学技术，特别是量子信息科学技术这一新兴领域的基石。该项目旨在在佛罗里达国际大学 (FIU) 物理系和 JILA 研究所的 JILA 物理前沿中心 (JILA PFC) 之间建立战略合作伙伴关系，以促进和推进两个机构 AMO 物理学的多样性和卓越研究。研究目标将通过两个主要研究方向（超冷原子物理学和单分子生物物理学）来实现，这两个方向旨在利用 JILA PFC 的世界级专家以及 FIU 的现有研究能力。该项目将通过实施 PREP 途径改进策略，改善两个机构中代表性不足群体的研究生的招募、保留和学位获得。此次合作将推进 AMO 物理学研究并提高两个机构研究生的多样性。 拟议的 FIU-JILA 合作伙伴关系将在两个主要领域进行研究，以推进 AMO 物理学，特别是在理解 (1) 超冷原子阵列中的多体物理学和 (2) 单分子生物物理学方面。在主旨 1 中，研究人员将使用基于飞秒激光的超快光谱学来研究多体效应，包括原子阵列中的相互作用、相关性和集体效应，以应用于基础多体物理和量子技术。他们还将使用飞秒脉冲来实现原子阵列中量子态的超快操纵。在主旨 2 中，最先进的单分子成像和测量技术，包括共焦和全内反射显微镜、基于纳米移液器的电化学技术与单分子荧光技术的集成、基于原子力显微镜的高将开发精密单分子力技术和分子动力学模拟，用于研究生物分子的折叠动力学和动力学以及细胞内单分子的传递和检测。该合作伙伴关系还将通过实施 PREP 路径改进策略（包括教师/学生互访、让本科生参与 JILA PFC 的夏季研究、让本科生和研究生参与 FIU 拟议的研究活动）来提高 FIU 和 JILA 物理研究生的多样性、学生指导以及在迈阿密菲利普和帕特里夏·弗罗斯特科学博物馆举办的公开讲座。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
