真空囚禁纳米粒子的非线性模式耦合与同步

Nonlinear mode-coupling and synchronization of a vacuum-trapped nanoparticle

Jan Gieseler, Marko Spasenovic, Lukas Novotny, Romain Quidant

摘要:

研究了高真空中激光捕获纳米粒子的动力学行为。使用与外部激发源的参数耦合,纳米颗粒振荡的线宽可以减少三个数量级。我们发现,纳米粒子的振荡和激发源是同步的,表现出明确的相位关系。此外,外部源可以用于可控地驱动纳米颗粒进入非线性区域,从而在纳米颗粒的不同平移模式之间产生强耦合。我们的工作有助于理解高真空中悬浮纳米粒子的非线性动力学,并为斑图形成,混沌和随机共振的研究铺平了道路。

英文摘要:

We study the dynamics of a laser-trapped nanoparticle in high vacuum. Using parametric coupling to an external excitation source, the linewidth of the nanoparticle's oscillation can be reduced by three orders of magnitude. We show that the oscillation of the nanoparticle and the excitation source are synchronized, exhibiting a well-defined phase relationship. Furthermore, the external source can be used to controllably drive the nanoparticle into the nonlinear regime, thereby generating strong coupling between the different translational modes of the nanoparticle. Our work contributes to the understanding of the nonlinear dynamics of levitated nanoparticles in high vacuum and paves the way for studies of pattern formation, chaos, and stochastic resonance.
