Heat transports driven by unidirectional rotations of cholesteric LC droplets

Abstract

Cholesteric LC droplets dispersed in an isotropic phase are known to exhibit unidirectional rotations under a temperature gradient. The phenomenon is understood as a typical cross-correlation and described by Onsager relations. Since the theory not only describes the observed phenomenon but also predicts the inverse process, we tried to verify it in this report. By unidirectionally rotating cholesteric droplets dispersed in an isotropic phase, we detected a slight temperature gradient induced in the LC cell.
