title: Spatiotemporal dynamics of optical molecular motors.
abstract: 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.
