Parametric Phase-Locking of Hydrogen-Bond Networks: High-Frequency Floquet Dressing of Liquid Water Topology

This work presents a theoretical framework for dynamically modifying the structural dynamics of liquid water using high-frequency parametric driving.

Modeling water as a dense network of interacting dipolar rotors, we analyze the effect of a fast, coherent electromagnetic field in the multi-terahertz regime using Floquet averaging techniques.

We show that high-frequency driving induces a renormalization of dipole-dipole interactions via a Bessel-function dependence, effectively modifying the orientational energy landscape.

This mechanism can significantly reduce rotational diffusion and extend hydrogen-bond lifetimes, leading to a transition toward a long-lived prethermal regime with enhanced structural correlations.

The model predicts a crossover from rapidly decorrelating liquid dynamics to a dynamically stabilized state with increased tetrahedral ordering under sufficiently strong driving.

This work provides a physically motivated framework for controlling the dynamics and topology of dipolar liquids through non-equilibrium parametric forcing.
