Nonetheless, the employment of FT on self-propelling objects has seldom been performed due to experimental difficulties. In this paper, we applied FT on a doublet that is comprised of asymmetrically coated self-propelling colloidal particles (Janus particles), which experiences a continuous rotation by applying AC electric field. We found that FT is valid for rotating self-propelling colloids by evaluating the estimated rotary torque to coincide with another form of torque estimation, which considers the rotation speed of the doublet and a simple Stokes equation.", "revisions": [ { "version": "v1", "updated": "2011-04-29T12:18:07.000Z" } ], "analyses": { "keywords": [ "fluctuation theorem", "self-propelling particles", "applying ac electric field", "simple stokes equation", "experimental difficulties" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1104.5607S" } } }
