This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Rydberg states are electronically excited orbitals in atoms or molecules whose energy structure approximately follow that observed in atomic hydrogen. Key to many breakthroughs in atomic, molecular and optical physics, research during the last decade has also shown that much of the physics governing Rydberg dynamics in cold atoms finds a natural extension in condensed matter, thus hinting at novel technologies that simultaneously benefit from Rydberg traits and a solid-state implementation. This proposal brings together experimentalists and theorists at the City College of New York (CCNY) and the Center for Ultracold Atoms at Harvard/MIT to advance the understanding of Rydberg physics in novel solid-state systems comprising two-dimensional materials and wide-bandgap semiconductors. This cross-disciplinary team is ideally positioned to advance the scientific knowledge of this field as it combines experts in atomic and condensed matter physics with a know-how encompassing optical spectroscopy, materials science, nanofabrication, and fundamental solid-state modeling. Adding to the scientific objectives, a key goal of this PREP project is to establish a formal partnership that simultaneously increases and enriches the participation of students and postdocs belonging to groups that are most underrepresented in physics. To this end, the group will capitalize on successful minority recruitment channels to reach the broadest student population.The work is organized around two distinct, though closely related material systems: The first set of activities zeroes in on the so-called “exciton-polaritons”, hybrid quasiparticles emerging from the strong coupling between excitons and photons in a cavity. The focus is on polaritons in transition metal dichalcogenides, whose Rydberg states will be investigated in the presence of magnetic field, strain, and dielectric engineering with special attention to polariton formation and non-linear interaction. Complementing this work, the group will investigate the formation of Rydberg states in neutral color centers in diamond, where hydrogenic orbitals — crudely associated to a hole revolving a negatively-charged core — emerge under resonant optical excitation. The group will experimentally explore and theoretically model Rydberg state dynamics in these systems, better understand the interplay between electronic spin polarization and Rydberg state creation, and investigate Rydberg blockade effects between adjacent color centers. The nature of the physical platforms investigated — at the center of broad ongoing efforts yet minimally explored in their connection with Rydberg physics — makes these activities of interest, particularly as a route to recreate in the solid state the features that make Rydberg states so attractive for applications in quantum information processing. In addition, an extensive set of initiatives is envisioned aimed at advancing the career paths of students and postdocs including a science communication bootcamp, an ethics training course, a professional development seminar series, and an annual research symposium. The group is committed to instilling a sense of community, which will be realized through a close interaction between participating students in the form of regular virtual meetings (either led by the PIs or taking place informally) and student exchange between groups.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.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。 Rydberg状态是原子或分子中的电子激发轨道，其能量结构大约遵循在原子氢中观察到的。在过去十年中的原子，分子和光学物理学的许多突破的关键也表明，控制冷原子中Rydberg动力学的许多物理学都发现了凝结物质的自然扩展，因此暗示了新型技术，这些技术简单受益于Rydberg Traits和Solid State的实施。该提议将纽约市学院（CCNY）和哈佛大学/麻省理工学院的Ultracold Atoms中心汇集了实验者和理论家，以促进新的固态系统中对Rydberg物理学的了解，该系统完成二维材料和宽带半导体。跨学科团队的理想位置可以推进该领域的科学知识，因为它将原子和凝结物理学专家与包括光谱，材料科学，纳米制作和基本固态建模的专家相结合。除科​​学目标外，该准备项目的一个关键目标是建立正式的伙伴关系，该伙伴关系简单地增加并丰富了属于物理学中人数最少的群体的学生和博士学位的参与。为此，该小组将利用成功的少数族裔招聘渠道，以达到最广泛的学生群体。这项工作是在两个不同的，但密切相关的材料系统的组织：第一组活动中的第一组活动零，即所谓的“激烈的 - 波利托人”，混合的准粒子，来自激进和照片之间的强大耦合而产生的混合式果皮。重点是过渡金属二分法中的极化子，在磁场，应变和饮食工程的存在下，将研究其rydberg状态，并特别注意北极星形成和非线性相互作用。对这项工作的补充，该小组将调查钻石中立色中心的Rydberg状态的形成，在钻石中，氢轨道与旋转负电荷的核心的孔相关 - 在谐振光学刺激下出现了。该小组将在这些系统中实验实验探索和理论模型Rydberg状态动力学，更好地了解电子自旋极化与Rydberg State创建之间的相互作用，并研究相邻颜色中心之间的Rydberg Blockade效应。所调查的物理平台的性质 - 在与Rydberg物理学有关的广泛努力中的中心，但最少探索了这些活动 - 尤其是作为在固态中重新创建的途径，使Rydberg Station使Rydberg Station对量子信息处理中的应用如此有吸引力。此外，还设想了一系列广泛的举措，旨在推进学生和博士后的职业道路，包括科学通信训练营，道德培训课程，专业发展开启的精确系列和年度研究研讨会。该小组致力于灌输一种社区意识，这将通过以定期虚拟会议的形式（由PI或非正式地进行）和学生交流之间的参与学生之间的紧密互动来实现。这一奖项反映了NSF的法定任务，并通过基金会的知识分子优点和广泛的影响来评估NSF的法定任务，并被认为是宝贵的支持。
