论文摘要
光的虚拟动量（IPM）被吸引了对偶极磁电颗粒的光学机械作用的异常起源，但在实验中却观察到。在这里，我们首次报告了整个高阶IPM力的家族，不仅用于磁电磁性，而且还用于通用的MIE颗粒，并在其内部激发了更高的多物。这种光力学现象源自IPM对光学力的非线性贡献，即使IPM小时，也可能是显着的。我们观察到具有涡旋状IPM流线的结构化光束中的高阶光学机制，这使低阶偶极贡献被抑制。我们的结果提供了第一个明确的证据，证明了IPM的洪代性质，扩展了光学力的分类，并为光学力和微观计量开放了新的可能性。
The imaginary Poynting momentum (IPM) of light has been captivated an unusual origin of optomechanical effects on dipolar magnetoelectric particles, but yet observed in experiments. Here, we report, for the very first time, a whole family of high-order IPM forces for not only magnetoelectric but also generic Mie particles, assisted with their excited higher multipoles within. Such optomechanical phenomena derive from a nonlinear contribution of the IPM to the optical force, and can be remarkable even when the incident IPM is small. We observe the high-order optomechanics in a structured light beam with vortex-like IPM streamlines, which allows the low-order dipolar contribution to be suppressed. Our results provide the first unambiguous evidence of the ponderomotive nature of the IPM, expand the classification of optical forces and open new possibilities for optical forces and micromanipulations.
