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."}],"author":[{"full_name":"Moyses, Henrique","first_name":"Henrique","last_name":"Moyses"},{"orcid":"0000-0002-7253-9465","full_name":"Palacci, Jérémie A","first_name":"Jérémie A","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","last_name":"Palacci"},{"full_name":"Sacanna, Stefano","first_name":"Stefano","last_name":"Sacanna"},{"first_name":"David G.","full_name":"Grier, David G.","last_name":"Grier"}],"doi":"10.1039/c6sm01163b","_id":"9052","citation":{"ieee":"H.
