Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

Magnonics addresses the dynamic excitations of a magnetically ordered material. These
excitations, referred to as spin waves and their quanta, magnons, are a powerful tool for …

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

The emergent field of cavity quantum materials bridges collective many-body phenomena in
solid state platforms with strong light–matter coupling in cavity quantum electrodynamics …

Bistable mechanical vibration is observed in a cavity magnomechanical system, which
consists of a microwave cavity mode, a magnon mode, and a mechanical vibration mode of …

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

The magnon cat state represents a macroscopic quantum superposition of collective
magnetic excitations of large number spins that not only provides fundamental tests of …

We report the first observation of the magnon-polariton bistability in a cavity magnonics
system consisting of cavity photons strongly interacting with the magnons in a small yttrium …

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 …

We realize a cavity magnon-microwave photon system in which a magnetic dipole
interaction mediates strong coupling between the collective motion of a large number of …
