空気界面を有したコレステリック液晶滴の温度差誘起ダイナミクス：トポロジー変化を伴う構造形成

抄録

Processes of the structural formation in a cylindrical cholesteric droplet with air interface were observed and analyzed. Appling a constant temperature gradient and cooing the droplet from the isotropic state, we obtained the cholesteric droplet via the isotropic-cholesteric coexistence state. After that, by performing specific heating and cooling operations, we obtained the cholesteric droplet with a different structure from that before the operations. It is considered that this structural change is due to the formation and recombination of defect structures during the heating and cooling operations.
