 abstract = {We describe colloidal Janus particles with metallic and dielectric faces
that swim vigorously when illuminated by defocused optical tweezers
without consuming any chemical fuel. Rather than wandering randomly,
these optically-activated colloidal swimmers circulate back and forth
through the beam of light, tracing out sinuous rosette patterns. We
propose a model for this mode of light-activated transport that accounts
for the observed behavior through a combination of self-thermophoresis
and optically-induced torque. In the deterministic limit, this model
yields trajectories that resemble rosette curves known as hypotrochoids.},
