Non-Hermitian physics basically due to the interplay between gain and loss has attracted considerable attention in the context of understanding various brand-new and counterintuitive physical phenomena. The major emphasis of this work is concerned with the chirality properties of chaotic motion in a whispering-gallery-mode microresonator based on nanoparticle-induced non-Hermitian mode coupling, which will be a challenging endeavor that is rarely presented in previous literature. By operating the nanoparticles in a whispering-gallery-mode microresonator, we achieved a dynamic control of chaotic behavior, and a rather more exotic finding is that the chaotic motion features chiral characteristics. Our results provide insight into nonlinear nano-optomechanics and fundamentally broaden the regime of chaotic dynamics. In addition, the proposal of chiral light chaos may offer attractive new prospects for the development of on-chip manipulation of chaotic light propagation and chiral photonic crystals, and could affect nanoscientific fields beyond optics.

基于非厄密模式的纳米粒子介导的手性光混沌。

在理解各种崭新且违反直觉的物理现象的背景下，非赫米特物理学基本上是由于增益和损耗之间的相互作用而引起了相当大的关注。这项工作的主要重点是在基于纳米粒子诱导的非厄密模式耦合的耳语画廊模式微谐振器中的混沌运动的手性特性，这将是一项极富挑战性的尝试，在以前的文献中很少提出。通过在回音壁模式微谐振器中操作纳米粒子，我们实现了对混沌行为的动态控制，而一个更为奇特的发现是，混沌运动具有手性特征。我们的结果提供了对非线性纳米光学力学的洞察力，并从根本上拓宽了混沌动力学的范围。此外，
