EAGER: Enabling Quantum Leap: Organic Magnonics for room temperature Quantum Logic

非技术性描述：随着电路极限的逼近，需要新的范例用于需要更少能量的未来几代更快的微型信息处理设备。目前，几乎所有现有的电子学都依赖于电子形式的电荷运动。电子还具有一种称为自旋的性质，这使它们具有磁性。这些磁性的周期性波动导致了被称为磁振子的波。Magnonics是一种新的范式，它使用Magnon来处理和存储信息，尽管与传统电子产品相比，它具有更低的能量损失和更高的速度。该项目的重点是研究在有机（即碳基）磁性材料中实现磁振子的物理机制。特别是，在有机磁性薄膜中的磁振子的控制，操纵，运输和非常灵敏的检测进行了研究。基于这样的磁体的磁装置使用电、磁和光学测量来设计、制造和测试。此外，实验工作的大型军火库的整合有助于有效地教育研究生和本科生谁是参与这个高度跨学科的研究项目在物理和化学之间的接口。此外，通过在该项目过程中开展的外联活动，高中和初中学生了解了物理、化学和自然科学的就业机会和技术潜力。技术说明：磁振子是S = 1的准粒子，它们服从玻色-爱因斯坦统计并且缺乏粒子的运动，但是它们与电子自旋的耦合可以用于信息传输，加工和储存。由此产生的技术，即Magnonics，预计将形成未来几代更快（GHz - THz频率）和减少能量耗散的微型信息处理设备的新范例。本计画的目标是增进对有机分子材料中磁振子的了解。后者被假设为上级传统的磁性材料，由于其长的磁振子平均自由程，使磁振子在室温和接近磁有序温度下在技术上是可行的。室温V（TCNE）x（TCNE =四氰基乙烯）磁体用作研究微谐振器中回音壁磁振子模式的磁振子增益介质，以进一步实现为高度相干的量子系统。该团队专注于薄膜生长和室温量子逻辑微腔的制造，使用宇称时间对称性。该项目利用了犹他州大学的大型实验能力，包括化学合成，聚合物和小分子沉积，磁传输，电检测铁磁共振，磁振子相关的自旋泵，逆自旋霍尔效应光谱，以及设备制造，加工和测试。此外，一个全新的电子类的广泛影响，使教育一批研究生和本科生谁是参与执行这个项目，以及推广到当地高中和中学社区。这个奖项反映了NSF的法定使命，并已被认为是值得通过评估使用基金会的智力价值和更广泛的影响审查标准的支持。

Nontechnical description: As the limits of electrical circuitry are approached, new paradigms are needed for future generations of faster miniature information processing devices that require less energy. Presently, nearly all existing electronics rely on the movement of electric charges in the form of electrons. Electrons also possess a property known as spin, that gives them their magnetic properties. Periodic undulations of these magnetic properties result in waves known as magnons. Magnonics is a new paradigm which uses magnons for processing and storing information, albeit with reduced energy losses and greater speeds compared to traditional electronics. This project focuses on the study of physical mechanisms that enable magnonics in organic (i.e. carbon-based) magnetic materials. In particular, the control, manipulation, transport and the very sensitive detection of magnons in organic magnetic thin films is investigated. Magnonic devices based on such magnets are engineered, fabricated and tested using electrical, magnetic and optical measurements. In addition, the integration of the large arsenal of experimental efforts serves to efficiently educate graduate and undergraduate students who are involved in this highly interdisciplinary research project at the interface between Physics and Chemistry. Furthermore, through outreach conducted in the course of this project, high school and middle school students learn about the career opportunities and technological potential of Physics, Chemistry and the Natural Sciences in general.Technical description: Magnons are S = 1 quasi-particles that obey Bose-Einstein statistics and lack movement of a particle, yet their coupling to electron spins can be utilized for information transport, processing and storage. The technologies resulting from this, namely Magnonics, are anticipated to form a new paradigm for future generations of faster (GHz - THz frequencies) and reduced energy dissipation of miniature information processing devices. The goal of this project is to enhance the understanding of magnons in organic-based molecular materials. The latter are hypothesized to be superior to traditional magnetic materials due to their long magnon mean free paths that enable magnonics to be technologically viable at room temperature and close to the magnetic ordering temperature. The room temperature V(TCNE)x (TCNE = tetracyano-ethylene) magnet serves as a magnonic gain medium for studying whispering gallery magnon modes in micro-resonators, for further implementation as highly coherent quantum systems. The team focuses on film growth and fabrication of microcavities for room-temperature quantum logic, using parity-time symmetry. This project utilizes the University of Utah's large arsenal of experimental capabilities, including chemical synthesis, polymer and small molecule deposition, magneto-transport, electrically-detected ferromagnetic resonance, magnon-related spin-pumping, inverse spin-Hall effect spectroscopy, as well as device fabrication, processing and testing. Furthermore, the broad impact of an entirely new class of electronics enables educating a cohort of graduate and undergraduate students who are involved in the execution of this project, as well as outreach to local high school and middle school communities.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.
