| Outline of Final Research Achievements |
When we add a temperature gradient to cholesteric droplets coexisting with isotropic phase, Lehmann effect causes torque and cholesteric droplets exhibit unidirectional rotation. In this study, we introduced azobenzene polymer between cholesteric droplets and substrates to lubricate surface friction. Photo-lubrication removes the effect of surface, which enable us to estimate the torque driven by a temperature gradient quantitatively by balance between Lehmann torque and viscosity torque.
