The route to chaos of a plasmonic dimer formed of two identical nanoparticles with Kerr‐type nonlinear response and illuminated by an external electric field is reported. It is shown that this system has a complex dynamical behavior with chaotic nature. This complexity is analyzed using Lyapunov exponents, the Kaplan–Yorke dimension, and correlation dimensions. The existence of familiar period‐doubling sequences route to chaos is pointed out, and domains corresponding to the onset of period doubling and chaos in the plane of parameters are evidenced.

非线性等离子体二聚体中混沌的研究途径

报告了由两个相同的具有Kerr型非线性响应的相同纳米粒子形成并由外部电场照亮的等离子体二聚体的混沌路线。结果表明，该系统具有复杂的动力学行为，具有混沌性质。使用Lyapunov指数，Kaplan-Yorke维和相关维来分析这种复杂性。指出了存在到混沌的倍频序列的存在，并证明了在参数平面上与倍频和混沌的开始相对应的域。
