dc.description.abstractEnWe theoretically study the motion of surface-active Janus particles, driven by an effective slip velocity due to a non-uniform temperature or concentration field ψ. With parameters realized in thermal traps, we find that the torque exerted by the gradient ∇ψ inhibits rotational diffusion and favors alignment of the particle axes. In a swarm of active particles, this polarization adds a novel term to the drift velocity and modifies the collective behavior. Self-polarization in a non-uniform laser beam could be used for guiding hot particles along a given trajectory.
