项目摘要

This award to Tulane University from the Major Research Instrumentation program and the Office of Multidisciplinary Activities of the Directorate for Mathematical and Physical Sciences supports the design and building of an advanced scientific tool for studying how matter and materials behave when they are placed in very strong magnetic field. This instrument will consist of two main parts: a very strong superconducting magnet and a set of lasers. Laser light will be used to probe how materials react to the strong magnetic field and to very low temperatures. Upon completion of the instrument development, the instrument will be available to outside user. The major science drivers of this instrument is in quantum matter, the advancement of our understanding of how electrons behave inside a wide variety of materials and imbue them with their properties, such as magnetism or superconductivity. Such basic scientific understanding underpins many technological marvels such as in medical diagnostic devices, computing chips in our phones and tablets, magnetic data storage technology, cell phone cameras, new energy-efficient LED light bulbs, and more. Through basic physics research, the proposed instrument will promote the progress of physics and advance national prosperity. This instrument will also contribute to advanced education of graduate and undergraduate students, thus building an educated national workforce for the new century. As a priority, the team of researchers promotes the participation in science and engineering fields of women and underrepresented minorities from Xavier University of Louisiana, a local Historically Black College or University.This award supports the development of a multi-user instrument for ultrafast terahertz (THz) spectroscopy in high magnetic fields of up to 17 T. The magnet cryostat provides the sample temperature control in the 2.5-300 K range and is cryogen-free. Four high-field experimental modalities will be available in both Faraday and Voigt optical configurations: i) THz time-domain spectroscopy based on photoconductive antennas with 0.2 - 3 THz spectral range; ii) time-resolved THz spectroscopy based on air-plasma THz generation and air-breakdown detection with 0.3 - 10 THz spectral range; iii) second harmonic generation with sample rotation about the surface normal; iv) optical pump-probe spectroscopy. The instrument will enable innovative research in magneto-electric excitations and optical nonreciprocity in multiferroics; search for the optical signatures of the chiral anomaly and the non-trivial band topology in Weyl semimetals; second harmonic generation and optical pump-probe studies of topological and magnetic materials; time-resolved THz spectroscopy of high-temperature superconducting pnictides. The instrument will become a part of the nationwide advanced research infrastructure. The instrument is unique, as it far outperforms in its specifications and capabilities other similar university-based research tools in the United States. In addition to eleven identified outside groups who have expressed a strong interest in the instrument capabilities in the nearest term.The instrument attracts potential local users and from across the Nation. The project contributes to the training of next the generation instrument developers. In the long run it will contribute to the education of dozens of graduate and undergraduate students. The project explicitly promotes the participation of women and underrepresented minorities in sciences and engineering.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.

该奖项由杜兰大学主要研究仪器项目和数学与物理科学理事会多学科活动办公室授予，支持设计和构建先进的科学工具，用于研究物质和材料在强磁场中的行为场地。该仪器将由两个主要部分组成：一个非常强的超导磁体和一组激光器。激光将用于探测材料对强磁场和极低温度的反应。仪器开发完成后，仪器将可供外部用户使用。该仪器的主要科学驱动力是量子物质，它促进了我们对电子在各种材料中如何表现的理解，并赋予它们诸如磁性或超导性等特性。这种基本的科学理解支撑着许多技术奇迹，例如医疗诊断设备、手机和平板电脑中的计算芯片、磁性数据存储技术、手机摄像头、新型节能 LED 灯泡等。通过基础物理研究，所提出的仪器将促进物理学的进步并促进国家的繁荣。该工具还将有助于研究生和本科生的高等教育，从而为新世纪建设一支受过教育的国家劳动力队伍。作为一个优先事项，研究人员团队促进路易斯安那州泽维尔大学（当地历史悠久的黑人学院或大学）的女性和代表性不足的少数族裔参与科学和工程领域。该奖项支持开发超快太赫兹多用户仪器（ THz）光谱可在高达 17 T 的高磁场中进行。磁体低温恒温器可将样品温度控制在 2.5-300 K 范围内，并且无需制冷剂。法拉第和 Voigt 光学配置将提供四种高场实验模式： i) 基于光电导天线的太赫兹时域光谱，光谱范围为 0.2 - 3 太赫兹； ii) 基于空气等离子体太赫兹产生和空气击穿检测的时间分辨太赫兹光谱，光谱范围为 0.3 - 10 太赫兹； iii) 样品绕表面法线旋转产生二次谐波； iv) 光泵浦探针光谱。该仪器将使多铁性磁电激发和光学非互易性的创新研究成为可能；寻找外尔半金属中手性异常和非平凡能带拓扑的光学特征；拓扑和磁性材料的二次谐波产生和光泵浦探针研究；高温超导磷族元素的时间分辨太赫兹光谱。该仪器将成为全国先进研究基础设施的一部分。该仪器是独一无二的，因为它的规格和功能远远优于美国其他类似的大学研究工具。除了十一个已确定的外部团体在最近的期限内对仪器功能表示强烈兴趣之外。该仪器吸引了潜在的本地用户和来自全国各地的用户。该项目有助于培训下一代仪器开发人员。从长远来看，它将为数十名研究生和本科生的教育做出贡献。该项目明确促进妇女和代表性不足的少数群体参与科学和工程。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，认为值得支持。
