Explore the intersection of electrostatics and active nematic liquid crystals in this 17-minute conference lecture from the Workshop on "Charged Soft Matter: Bridging Theory and Experiment." Discover how liquid crystals offer enhanced charge control capabilities compared to isotropic fluids through their higher degree of order, with charge localization occurring in topological defects of the orientational order. Learn about the investigation of flexoelectricity and ion partitioning effects on ion-doped 2D active nematic liquid crystals through numerical simulations and theoretical analysis. Examine ion current and magnetic field distribution around single topological defects in active nematics, and understand how ions influence active turbulence dynamics. Gain insights into how ion-doped active nematics can generate voltage through magnetic flux variations induced by moving topological defects, revealing new possibilities for charge control in complex fluid systems beyond traditional surface-based methods.
