Precision laser levitation for quantum metrology and gravitational sensing

用于量子计量和引力传感的精密激光悬浮：该奖学金项目旨在仅使用激光束悬浮宏观物体，为测试物理理论提供新工具。强激光束可以施加足够的力来抵消重力，使物体悬浮起来。与其他悬浮形式相比，激光悬浮是无散射的，并且可以保持系统的相干性。它具有上级光学和机械品质因数，并保留了系统动力学的完整信息。这使得激光悬浮成为一种高度可控和超灵敏的设备，能够检测微小的环境变化。本研究旨在探讨量子物理与重力物理之间的关系，并将激光悬浮技术发展成为一种精密的重力测量仪器。激光悬浮技术具有发展成为矿产勘探和环境传感技术的潜力。

Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has superior optical and mechanical quality factors and complete information of the system dynamics is retained. This allows laser levitation to be turned into a highly controllable and ultra-sensitive device capable of detecting minute environmental changes. This research aims to probe the relationship between quantum and gravitational physics and develop laser levitation into a precision instrument for the sensing of gravity. Laser levitation has the potential to be developed into technology for mineral exploration and environmental sensing.
