We present an experimental realization of a biased optical periodic potentialin the low friction limit. The noise-induced bistability between locked(torsional) and running (spinning) states in the rotational motion of ananodumbbell is driven by an elliptically polarized light beam tilting theangular potential. By varying the gas pressure around the point of maximumintermittency, the rotational effective diffusion coefficient increases by morethan 3 orders of magnitude over free-space diffusion. These experimentalresults are in agreement with a simple two-state model that is derived from theLangevin equation through using timescale separation. Our work provides a newexperimental platform to study the weak thermal noise limit for diffusion inthis system.
