Wave-particle Interactions in a Resonant System of Photons and Ion-solvated Water

TL;DR

This paper models a resonant photon-ion water system combining superradiation and wave-particle interactions, revealing a mechanism for dynamical coherence through collective instability, akin to free electron laser dynamics.

Contribution

It introduces a novel laser model for photon-ion water interactions that integrates Dicke superradiation with wave-particle dynamics, linking it to free electron laser systems.

Findings

Equations of motion resemble those of free electron lasers

Identifies a mechanism for dynamical coherence via collective instability

Demonstrates wave-particle interaction leads to superradiance-like behavior

Abstract

We investigate a laser model for a resonant system of photons and ion cluster-solvated rotating water molecules in which ions in the cluster are identical and have very low, non-relativistic velocities and direction of motion parallel to a static electric field induced in a single direction. This model combines Dicke superradiation with wave-particle interaction. As the result, we find that the equations of motion of the system are expressed in terms of a conventional free electron laser system. This result leads to a mechanism for dynamical coherence, induced by collective instability in the wave-particle interaction.
