水分子之间的氢键相互作用在水的化学反应性、动态质子迁移率、静态介电行为和热力学性质中起着关键作用。在这项研究中，我们证明了水的离子电导率的修改，通过杂交与真空电磁场通过强耦合的O-H伸缩模式的水的法布里-珀罗腔模式。杂交产生集体振动极化激元状态，从而提高质子电导率的数量级共振。此外，介电常数在耦合状态下的谐振时增加。本文中提出的研究结果揭示了如何设计真空电磁环境来控制水的基态性质。
Hydrogen bonding interactions among water molecules play a critical role in chemical reactivity, dynamic proton mobility, static dielectric behavior, and the thermodynamic properties of water. In this study, we demonstrate the modification of ionic conductivity of water through hybridization with a vacuum electromagnetic field by strongly coupling the O-H stretching mode of H2O to a Fabry-Perot cavity mode. The hybridization generates collective vibro-polaritonic states, thereby enhancing the proton conductivity by an order of magnitude at resonance. In addition, the dielectric constants increase at resonance in the coupled state. The findings presented herein reveal how a vacuum electromagnetic environment can be engineered to control the ground-state properties of water.
