使用数值和实验工具，我们研究了两个耦合的螺旋形核心的Belousov-Zhabotinsky反应的光敏变体的运动。每个核心都位于一个单独的二维域上，并通过光耦合到另一个。当两个螺旋具有相同的旋转方向时，芯被吸引到具有以螺旋波长λ的整数单位量化的直径的圆形轨迹。当螺旋具有相反的旋转方向时，核心被吸引向不同但平行的直线轨迹，间隔λ/2的整数倍。我们提出了一个模型，解释这种行为的结果，螺旋波前的核心相互作用，产生一个确定性的位移的核心和其相位的延迟。
Using numerical and experimental tools, we study the motion of two coupled spiral cores in a light-sensitive variant of the Belousov-Zhabotinsky reaction. Each core resides on a separate two-dimensional domain, and is coupled to the other by light. When both spirals have the same sense of rotation, the cores are attracted to a circular trajectory with a diameter quantized in integer units of the spiral wavelength λ. When the spirals have opposite senses of rotation, the cores are attracted towards different but parallel straight trajectories, separated by an integer multiple of λ/2. We present a model that explains this behavior as the result of a spiral wavefront-core interaction that produces a deterministic displacement of the core and a retardation of its phase.
