AI 中文摘要
高折射率粒子近来在光悬浮实验中受到越来越多的关注，其能通过电磁米氏共振进一步调控光力。与主要在偶极区被捕获、捕获频率主要由材料密度决定的标准二氧化硅粒子不同，由高折射率粒子构成的共振超原子能展现出全新的捕获行为。本研究实验探究了光学驻波中共振硅粒子的捕获情况，通过直接对比硅与二氧化硅粒子，揭示了二者在光力标度和捕获动力学上的根本差异。除了在强度极大值处的常规捕获，我们还实现了硅纳米粒子在光学强度极小值中的确定性稳定三维捕获，而二氧化硅粒子无法进入该区域。通过与蓝失谐原子捕获进行介观类比，我们的结果表明超原子是拓展光操控工具箱、进入新型捕获区域（例如近表面区域）的通用方法。
英文摘要
High-refractive-index particles have recently attracted a growing interest in optical levitation experiments, offering the ability to further engineer optical forces through electromagnetic Mie resonances. Unlike standard silica particles, which are predominantly trapped in the dipole regime and exhibit trap frequencies mainly determined by material density, resonant meta-atoms formed by high-index particles enable qualitatively new trapping behaviors. In this work, we experimentally investigate the trapping of resonant silicon particles in an optical standing wave. A direct comparison of silicon and silica highlights the fundamental differences in their optical force scaling and trapping dynamics. Beyond conventional trapping at intensity-maxima, we demonstrate deterministic and stable three-dimensional trapping of silicon nanoparticles in optical intensity minima, a regime that remains inaccessible for silica particles. Drawing a mesoscopic analogy with blue-detuned atom trapping, our results establish meta-atoms as a versatile approach to further extend the optical manipulation tool box towards accessing novel trapping regimes e.g. in close proximity to a surface.
