Hybrid Magnon Modes

Magnons are the fundamental excitations of magnetically ordered materials and span frequencies from GHz to THz at wavelengths down to the nm-regime. Because of their convenient frequencies and wavelengths, they have been considered for computational applications by encoding information into their phase and amplitude. Furthermore, the energy and spatial distribution of magnons can be readily manipulated via applied magnetic fields, which provides an easy pathway for controllable interactions. Concurrently, magnons readily interact with a wide variety of different excitations, including microwave and optical photons, phonons, and other magnons. Such hybrid magnon dynamic excitations have gained increased interest due to their potential impact on coherent information processing [1]. This in turn may also open up new pathways for hybrid quantum information systems [2].
