New Model Simulates Dynamics in Cavity Electromagnonic Systems

A new paper titled "Dynamical phase-field model of cavity electromagnonic systems" by Shihao Zhuang and colleagues presents a model that simulates the dynamics of electromagnetic waves, magnetization, and strain in three-dimensional multiphase systems. The authors report that this model can effectively simulate the coupled dynamics of photons, magnons, and acoustic phonons, which are fundamental components in various physical systems.

The study highlights several applications of the model, including the excitation of hybrid magnon-photon modes, known as magnon polaritons, and phenomena such as Floquet-induced magnonic Aulter-Townes splitting. The authors also demonstrate the capability of the model to predict the dynamics of energy exchange between these modes, which is crucial for advancements in quantum sensing and communication technologies.

Additionally, the researchers designed a cavity electro-magno-mechanical system that facilitates a triple resonance involving phonons, magnons, and photons. This system enables the resonant excitation of transverse acoustic phonon modes by magnon polaritons, showcasing the model's potential for practical applications.

The findings suggest that the dynamical phase-field model serves as a valuable computational tool for guiding the fabrication of cavity electromagnonic systems and optimizing their operational conditions. This could have significant implications for future developments in quantum technology and materials science.
