ExpandQISE: Track 1: Light-controlled magnetism in Floquet-Bloch systems

摘要：材料合成和纳米技术的最新进展导致了量子约束和电子相互作用产生的具有优异性能的新材料的发现，为量子材料领域开辟了道路，并为未来高性能电子学建立了新的平台。在所有情况下，量子系统的实际应用都带来了培训广泛而多样化的劳动力的挑战，这是将所有这些潜力转化为现实所必需的。该项目侧重于劳动力培训，同时探索在高强度光场照射下量子材料中的光-物质相互作用，在这种情况下，光可以改变材料特性并根据需要创建新的量子态。在乔治城大学的指导下，该项目将变革性研究与新墨西哥理工学院量子材料和技术新教育计划的发展相结合，并有可能吸引其他新墨西哥学院和大学的学生参与。研究活动、课程开发和机构之间的合作为西班牙裔和其他未被充分代表的少数民族学生提供不同层次的量子材料教育和培训。技术摘要：该项目的科学目标是通过实验（新墨西哥理工大学，乔治城大学）和理论（智利大学圣地亚哥分校）的协同作用来研究Floquet-Bloch系统中的光致磁性。具体来说，本项目提出了二维材料（石墨烯、MoS2、WS2）和三维材料（石墨）中Floquet-Bloch态的磁强观测实验。磁强计是一种新颖而有前途的Floquet Bloch态检测方法。本项目提出的Floquet- bloch态的磁强学研究的具体实验重点是开发一种用于Floquet研究的灵敏磁强学测量技术，实现二维材料中Floquet边缘态相关电流的磁检测：1)Floquet边缘态相关电流；2)预测石墨烯中自发非平衡磁性的发生；3)过渡金属二硫族化合物中磁谷电子现象的观察；4)三维材料中Floquet-Bloch态的磁检测。该项目由多学科活动办公室（MPS/OMA）、促进竞争研究的既定计划（EPSCoR）和技术前沿计划（TIP/TF）共同资助。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Non-technical Abstract: Recent advancements in material synthesis and nanotechnology have led to the discovery of new materials with superior properties that arise from quantum confinement and electronic interactions, opening the way to the field of quantum materials and attractive prospects to establish new platforms for future high-performance electronics. In all cases, the practical use of quantum systems brings the challenge of training the broad and diverse workforce that is necessary to transform all this potential into a reality. This project focuses on workforce training while exploring light-matter interaction in quantum materials under irradiation with high-intensity optical fields, in a regime where light can change the material properties and create new quantum states on demand. This project combines transformative research with the development of a new education program in quantum materials and technologies at New Mexico Tech, under the Georgetown University mentorship, with the possibility of involvement of students from other New Mexico colleges and universities. The research activity, curriculum development, and collaboration between institutions provide education and training in quantum materials to Hispanic and other underrepresented minority students at different levels. Technical Abstract: The project's scientific goal is to investigate light-induced magnetism in Floquet-Bloch systems with a synergy of experiment (New Mexico Tech, Georgetown University) and theory (University of Chile-Santiago). Specifically, this project proposes experiments for the magnetometric observation of Floquet-Bloch states in 2D materials (graphene, MoS2, WS2) and 3D materials, e.g., graphite. Magnetometry is a novel and promising approach for detecting Floquet Bloch states. The specific experiments on magnetometry studies of Floquet-Bloch states proposed in this project focus on the development of a sensitive magnetometric measurement technique for Floquet research towards magnetic detection of: 1) Floquet edge-states-related currents in 2D materials; 2) the predicted occurrence of spontaneous non-equilibrium magnetism in graphene; 3) the observation of magneto- valleytronic phenomena in transition metal dichalcogenides and 4) magnetic detection of Floquet-Bloch states in 3D materials.This project is jointly funded by The Office of Multidisciplinary Activities (MPS/OMA), the Established Program to Stimulate Competitive Research (EPSCoR), and Technology Frontiers Program (TIP/TF).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.
