论文摘要
在这项工作中，在轴对称光场的影响下进行了自旋转随机粒子的动力学。所考虑的粒子具有在偏心位置携带光传感器的主要特征。对于所选的实验条件，新兴轨迹是轨道，更有趣的是，它们提出了两个优先的径向距离。引入了包含关键实验组件的数学模型。通过数值模拟和理论分析，发现除了轨道行为外，传感器位置还可以产生被困或扩散的行为。此外，该研究表明，随机扰动和传感器的偏心位置负责诱导轨道轨迹的活性，这与实验观察结果一致。
In this work, the dynamics of a self-propelled stochastic particle under the influence of an axisymmetric light field was experimentally studied. The particle under consideration has the main characteristic of carrying a light sensor in an eccentric location. For the chosen experimental conditions, the emerging trajectories were orbital, and, more interestingly, they presented two preferential radial distances. A mathematical model incorporating the key experimental components was introduced. By means of numerical simulations and theoretical analysis, it was found that, in addition to the orbiting behavior, the sensor location could produce trapped or diffusive behaviors. Furthermore, the study revealed that stochastic perturbation and the eccentric location of the sensor are responsible for inducing bistability in the orbital trajectories, in agreement with the experimental observations.
