Making isotropic droplets in the cholesteric (Ch) liquid crystal, we found spiral textures appear on the interface between the Ch liquid crystal and the droplets. Moreover, applying temperature gradient to this system, we found the texture rotates. To clarify the origin of this heat-driven rotation, we analyzed the flow field in the system. As a result, it was found convection is induced in the droplet when temperature gradient is applied; thus, we concluded this convection is the physical origin of the heat-driven rotation.
