标题： Remote electric-field control of antiferromagnetic magnon-polaritons

摘要： 混合光-物质态的控制，特别是由磁子和腔体光子强耦合产生的磁极化子，仍然是开发可重构量子和经典器件的关键挑战。 在这里，我们展示了通过将高双折射液晶层集成到包含反铁磁晶体的太赫兹法布里-珀罗腔中，使用电场在室温下远程控制反铁磁磁极化子的能力。 位于磁性材料几毫米远处的液晶可以通过电场调整腔体的光子环境。 这种调整反过来会影响特定腔体模式与磁子共振的耦合强度，从而控制腔体光子对磁子的修饰程度。 我们的方法实现了无需直接电气接触或改变磁性介质即可动态且可逆地调节磁子-光子杂化。 这些发现为电压可编程的太赫兹磁子器件创造了条件，并为基于自旋的信息处理技术中的非侵入式控制策略提供了新可能性。 显示英文摘要

摘要： The control of hybrid light-matter states, specifically magnon-polaritons that emerge from the strong coupling between magnons and cavity photons, remains a key challenge in developing reconfigurable quantum and classical devices. Here, we showcase the ability to remotely control antiferromagnetic magnon-polaritons at room temperature using electric field by integrating a highly birefringent liquid crystal layer into a terahertz Fabry-P\'erot cavity containing an antiferromagnetic crystal. Positioned several millimeters from the magnetic material, the liquid crystal allows for adjusting the cavity's photonic environment through electric field. This adjustment, in turn, influences the coupling strength of a particular cavity mode to the magnon resonance, thereby controlling the extent of magnon dressing by cavity photons. Our approach facilitates dynamic and reversible tuning of magnon-photon hybridization without the need for direct electrical contact or alterations to the magnetic medium. These findings create the conditions for voltage-programmable terahertz magnonic devices and new possibilities for noninvasive control strategies in spin-based information processing technologies.
