Our recent Perspective article on “Hybrid magnonics: Physics, circuits, and applications for coherent information processing” was featured by the Journal of Applied Physics.  This perspective article focuses on the fundamental physics and device application of hybrid magnon modes, particularly with their potential for coherent information processing.  This build on the recent rapid developments of magnon-based hybrid systems, which seek to combine magnonic excitations with diverse excitations for transformative applications in devices, circuits, and information processing. Key to their promising potentials is that magnons are highly tunable excitations and can be easily engineered to couple with various dynamic media and platforms.
