摘要

在反传播双光束光阱中，粒子的半径和折射率几乎不受约束。基于真空双光束的特性，设计了一种微纳弱重力机械传感器。该传感器提高了对粒子重力的响应范围aN~pN和精度。此外，我们的工作可能有助于表征其他短程物理，如卡西米尔力。

Sensing of Gravity with Micro-Nano Particles using Counter-Propagating Dual-Beam Optical Trap

The radius and refractive index of particles is almost unconstrained in counter-propagating dual-beam optical trap. We demonstrate a micro-nano mechanical sensor for weak gravity based on the characteristics of dual-beam in vacuum. The sensor improves the response range aN~pN and accuracy of gravity for particles. Furthermore, our work may be useful for characterizing other short-range physics such as Casimir forces.
