Cavity Spintronics is a newly developing interdisciplinary field that started around 2014. It utilizes cavity techniques, which have transformed many other disciplines, to investigate the strong light--matter interaction between magnetic materials and electromagnetic waves. Via the quantum physics of spin--photon entanglement on the one hand, and via classical electrodynamic coupling on the other, the emergence of this field connects some of the most exciting modern physics, such as quantum information and quantum optics, with one of the oldest sciences on the earth, magnetism. Now is the right time to harness the new physics of cavity spintronics to expand the horizons for microwave, THz, magnetic, and quantum technologies. Also key to the timing of this proposal is our own research momentum built up in the past 4 years, during which my students and I have made original and unique contributions to reveal and utilize the physics of the cavity magnon polariton (CMP), a versatile quasi-particle that has both spin and photon characteristics.     Building on these opportunities, the goals of my research program are to use cavity spintronics approaches to address the fundamental questions of light--matter interaction in spin-photon coupled systems, and to create novel devices for innovating microwave, THz, magnetic, and quantum technologies. Our unique advantage stems from our world--leading ability to electrically detect CMP with high sensitivity, the ability to directly probe both the amplitude and phase of CMP, the proficiency of fabricating on--chip high--quality cavity circuits, and the capacity of the research infrastructure in my lab which was renovated in the past 5 years with a vast set of tools for performing cavity spintronics experiments at extreme conditions (such as in high magnetic fields, at ultra-low temperatures, and with ac modulations up to high frequencies). We will use these techniques to study ferromagnetic metals, ferromagnetic insulators, antiferromagnets, as well as hybrid devices with tailored functions made of the combination of these materials and high--quality cavities. Examples of key topics that we will work on include inventing the CMP--based solid-state maser, developing non-reciprocal control of microwave transmission, exploring THz cavity spintronics, and facilitating industrial applications of cavity--enhanced sensing. Existing industrial collaborations with researchers at BlackBerryr, Everspin, and OPI Systems will allow rapid translation of advances in my lab into either proof- of- concept or prototype devices for commercial use, and will therefore have a significant impact in the quickly advancing field of cavity spintronics. Funding for this program will be primarily used for supporting 4 graduate and 2 undergraduate students (every year), training them to gain unique skills highly desirable in the knowledge-intensive information and communication technology (ICT) sector of the Canadian economy.

腔体旋转技术是一个新开发的跨学科领域，始于2014年。它利用了腔技术，它改变了许多其他学科，研究了磁性材料与电磁波之间的强光 - 物质相互作用。通过旋转的量子物理 - 一方面，以及通过经典的电动力耦合，该领域的出现将一些最令人兴奋的现代物理（例如量子信息和量子光学器件）与地球上最古老的科学联系起来。现在是利用新的腔体旋转物理物理学扩展微波炉，THZ，磁性和量子技术的地平线的合适时机。该提案时机的关键也是我们自己的研究势头，在过去的四年中建立了自己的研究势头，在此期间，我和我的学生做出了原始和独特的贡献，以揭示和利用型号镁质北极星（CMP）的物理，这是一种多功能的准准晶石，它具有旋转和光子特性。在这些机会的基础上，我的研究计划的目标是使用腔体旋转方法来解决自旋光子耦合系统中光线相互作用的基本问题，并为创新的微波炉，THZ，磁性和量子技术创建新颖的设备。我们独特的优势产品从世界领先的能力（以高灵敏度来检测CMP），能够直接探测CMP的放大器和阶段的能力，在我的实验室中，在过去5年中，在我实验室中改革了高品质的型腔循环的芯片高 - 质量型腔循环的能力以及在我实验室中进行了5年改革的工具，该工具的经验量很高。在超低温度下以及AC调制时，磁场至高频率）。我们将使用这些技术来研究铁磁金属，铁磁绝缘子，抗铁磁磁体以及具有由这些材料组合和高质量腔的量身定制功能的混合设备。我们将致力于的关键主题的例子包括发明基于CMP的固态MASER，开发微波传输的非重新控制控制，探索Thz腔体旋转学以及支持空腔的工业应用 - 增强灵敏度。与BlackBerryR，Everspin和OPI Systems的研究人员进行的现有工业合作将使我的实验室进步快速转化为概念验证或原型设备，以供商业使用，因此将对快速前进的空腔旋转型领域产生重大影响。该计划的资金将主要用于支持4名研究生和2名本科生（每年），培训他们在加拿大经济的知识密集型信息和通信技术（ICT）领域获得高度期望的独特技能。
