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.

该项目旨在开发先进技术来光学悬浮宏观（毫米级）物体和纳米级（原子薄）材料。研究小组建造的悬浮平台是基于激光束的共振放大辐射压力。这种新型光学悬浮可以将系统与外部噪声完全隔离，从而使它们能够对微妙的环境变化做出极快的响应。这些平台可以变成锋利的仪器，用于测量感兴趣的计量变量和探索新的物理现象。可以开发量子光学技术来优化悬浮系统的灵敏度，使其达到允许探索量子和引力物理的水平。
