This project aims to develop advanced technologies to optically levitate macroscopic (millimetre-sized) objects and nanoscopic (atomically thin) materials. Levitation platforms built by the investigatory team are based on the resonantly amplified radiation pressure of laser beams. This new type of optical levitation can provide ultimate isolation of the systems from external noise, making them extremely responsive to subtle environmental changes. These platforms could be turned into sharp instruments for measuring metrological variables of interest and probing new physics. Quantum optical techniques could be developed to optimise the sensitivity of levitated systems to levels that allow the exploration of quantum and gravitational physics.

该项目旨在开发光学悬浮宏观（毫米大小）物体和纳米（原子薄）材料的先进技术。课题组建立的悬浮平台是基于激光束共振放大的辐射压力。这种新型的光学悬浮可以提供系统与外部噪音的最终隔离，使它们对细微的环境变化非常敏感。这些平台可以变成测量感兴趣的计量变量和探索新物理的尖锐工具。量子光学技术可以优化悬浮系统的灵敏度，使其达到探索量子和引力物理的水平。
