Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

Quantum information technology based on solid state qubits has created much interest in
converting quantum states from the microwave to the optical domain. Optical photons, unlike …

Hybrid dynamic systems have recently gained interest with respect to both fundamental
physics and device applications, particularly with their potential for coherent information …

We report dissipative magnon-photon coupling caused by the cavity Lenz effect, where the
magnons in a magnet induce a rf current in the cavity, leading to a cavity backaction that …

Magnon–polaritons are hybrid light–matter quasiparticles originating from the strong
coupling between magnons and photons. They have emerged as a potential candidate for …

We experimentally demonstrate magnon Kerr effect in a cavity-magnon system where
magnons in a small yttrium iron garnet (YIG) sphere are strongly but dispersively coupled to …

Coherent conversion of microwave and optical photons in the single quantum level can
significantly expand our ability to process signals in various fields. Efficient up-conversion of …

We experimentally implement a system of cavity optomagnonics, where a sphere of
ferromagnetic material supports whispering gallery modes (WGMs) for photons and the …

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic
phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This …

Nonlinear magnonics studies the nonlinear interaction between magnons and other
physical platforms (phonon, photon, qubit, spin texture) to generate novel magnon states for …
