The spatiotemporal dynamics of optical molecular motors is simulated on the basis of a spatially resolved model. A spatially dependent Fokker-Planck model for the molecular motors is linked with Maxwell's wave equation describing the external excitation via a spatially inhomogeneous light field. Simulations show that strong diffusion of the embedding fluent leads to increased motor dynamics while in inhomogeneous ensembles motor clustering may occur. Spatially inhomogeneous optical excitation may provide a means of movement control of the molecular motors.
基于空间分辨模型对光学分子马达的时空动力学进行了模拟。用于分子马达的空间相关福克 - 普朗克模型通过空间不均匀光场与描述外部激发的麦克斯韦波动方程相联系。模拟结果表明,嵌入流体的强扩散会导致马达动力学增加,而在不均匀集合中可能会出现马达聚集现象。空间不均匀的光激发可能提供一种控制分子马达运动的方法。
