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 …

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

We reveal the cooperative effect of coherent and dissipative magnon-photon couplings in an
open cavity magnonic system, which leads to nonreciprocity with a considerably large …

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 …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

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 …

We demonstrate strong magnon-photon coupling of a thin-film Permalloy device fabricated
on a coplanar superconducting resonator. A coupling strength of 0.152 GHz and a …
