论文摘要
采用旋转式启发的方法，我们研究了单轴列中电解质的离子电荷电流与列质质地动力学之间的相互耦合。假设流体动力学淬灭，我们类似于自旋扭矩和自旋泵的运动方程。基于能量耗散的原则，我们得出了离子电流在列表主管领域施加的绝热“固化扭矩”，以及由于主管的方向动力学而引起的离子的相互动力。我们讨论了几个简单的示例，以说明该耦合的潜在功能。此外，使用我们的现象学框架，我们提出了一种实用方法，以通过对列明细胞的阻抗测量提取耦合强度。探索基于这种物理学的进一步应用可以促进nematic -nematic Iontronics的发展。
Adopting a spintronics-inspired approach, we study the reciprocal coupling between ionic charge currents and nematic texture dynamics in a uniaxial nematic electrolyte. Assuming quenched fluid dynamics, we develop equations of motion analogously to spin torque and spin pumping. Based on the principle of least dissipation of energy, we derive the adiabatic "nematic torque" exerted by ionic currents on the nematic director field as well as the reciprocal motive force on ions due to the orientational dynamics of the director. We discuss several simple examples that illustrate the potential functionality of this coupling. Furthermore, using our phenomenological framework, we propose a practical means to extract the coupling strength through impedance measurements on a nematic cell. Exploring further applications based on this physics could foster the development of nematronics -- nematic iontronics.
