20.500.12556/RUL-155550 Nematronics: reciprocal coupling between ionic currents and nematic dynamics 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. condensed matter physics nematic liquid crystals ionic fluids fizika kondenzirane snovi nematski tekoči kristali ionske tekočine true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-05 13:18:42 2024-04-05 13:18:43 2024-04-06 04:17:39 0000-00-00 00:00:00 2023 0 0 Str. 168102-1-168102-7 iss. 16 Vol. 130 2023 0000-00-00 Zaloznikova NiDoloceno apc 0000-00-00 0000-00-00 2023-04-21 538.9 0031-9007 10.1103/PhysRevLett.130.168102 150353923 Clanek_Ravnik.pdf Clanek_Ravnik.pdf 1 56A0F39DF3E780EC68AE9ECF0F977282 89552327abbcf4b2d2284ba1b5480113f3b2b4653ade5760b33064737eed8e85 701530e7-f33e-11ee-afc9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182508 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.168102 0 7b68e4b4-f33e-11ee-afc9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182509 Fakulteta za matematiko in fiziko 0 0 0
