论文摘要
纳米颗粒的悬浮在各个研究分支中至关重要。 Casimir部队是应对它的天然候选人,但缺乏宽带超材料排除了真空中的排斥力。我们仅基于宽带超材料完美磁导体表面的设计显示真空中的亚微米纳米颗粒悬浮液,其中大部分力是由(量子)零点的贡献给出的。在质量动力学中心的谐波方向上,特征频率线性地取决于普朗克的常数$ \ hbar $,而独立于纳米粒子的体积。
The levitation of nanoparticles is essential in various branches of research. Casimir forces are natural candidates to tackle it but the lack of broadband metamaterials precluded repulsive forces in vacuum. We show sub-micron nanoparticle levitation in vacuum only based on the design of a broadband metamaterial perfect magnetic conductor surface, where the force is mostly given by the (quantum) zero-point contribution. In the harmonic regime of the center of mass dynamics, the characteristic frequency depends linearly on Planck's constant $\hbar$ while independent of the nanoparticle's volume.
