Electronic and magnetic spectroscopy system for spin-optomechanics

光机械装置利用光作为标尺来测量机械物体位置的微小波动。这些设备可以在从大质量（例如LIGO）到微观（例如激光捕获原子的振动）的尺度上实现，并且是机械物体的基础研究以及检测力和存储信息的实用仪器的基础。本研究工具和仪器请求中描述的设备迫切需要使用光机械设备进行世界领先的实验，以控制和测量材料的纳米级电子和磁性-自旋-这是未来量子信息处理和传感技术的基本要素。所需的设备资金补充了2016年授予巴克莱实验室的NSERC发现，加速器和战略合作伙伴关系资金，以支持HQP研究自旋光力学，并且对于这些HQP成功完成其项目至关重要。

Optomechanical devices use light as a ruler to measure miniscule fluctuations in the position of mechanical objects. These devices can be implemented over size scales ranging from massive (e.g., LIGO) to microscopic (e.g. vibrations of laser trapped atoms), and underlie fundamental studies of mechanical objects as well as practical instruments for detecting forces and storing information. The equipment described in this request for Research Tools and Instruments is urgently needed to perform world leading experiments using optomechanical devices to control and measure nanoscale electronic and magnetic properties of materials - spins - that are essential elements for future quantum information processing and sensing technologies. The requested funding for equipment complements NSERC Discovery, Accelerator and Strategic Partnership funding awarded to the Barclay lab in 2016 to support HQP researching spin-optomechanics, and is critically needed for these HQP to successfully complete their projects. During the past two years HQP in the Barclay lab have developed nanoscale optomechanical devices that are breakthroughs on two fronts: they have demonstrated one of the first applications of a nanoscale cavity optomechanical sensor, and have created the world’s first single crystal diamond optomechanical devices. In addition to displaying properties such as record low mechanical dissipation and high sensitivity to external forces, these devices are among the first to connect cavity optomechanics with electronic and magnetic spins. If they can be operated at low temperature and in precisely controlled magnetic and RF fields, and if their spins can be precisely addressed, they offer an unrivaled platform for optomechanically probing and controlling spin systems and will be of intense interest for quantum information processing applications. However, the apparatus needed to achieve these requirements is not currently available in the Barclay lab. This request for research tools and instruments addresses this deficiency, and will enable the exceptional performance and spin hosting ability of devices in the Barclay lab to be harnessed by HQP for demonstrations of never before observed coupling between light, mechanical vibrations, and spins. Achieving such photon-phonon-spin coupling is a major goal of several international research groups, and with the requested equipment HQP in the Barclay lab will be in a leading position to achieve this goal first. This apparatus will also enable optomechanical detection of the properties of magnetic nanostructures with world record sensitivity. Such studies will make major impacts and further strengthen Canada’s position as a leader in the emerging field of spin-optomechanics. Without the requested equipment, this advantage will be lost as competing researchers catch up, and the impact of the work will be severely diminished.
