Experiments during the past 2 years have shown strong resonant photon-magnon coupling
in microwave cavities, while coupling in the optical regime was demonstrated very recently …

Rigidity of an ordered phase in condensed matter results in collective excitation modes
spatially extending to macroscopic dimensions. A magnon is a quantum of such collective …

Coherent conversion of photons to magnons, and back, provides a natural mechanism for
rapid control of interactions between stationary spins with long coherence times and high …

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

We analyze the magnetic dipole coupling of an ensemble of spins to a superconducting
microwave stripline structure, incorporating a Josephson junction based transmon qubit. We …

We observe a power-dependent anticrossing of Walker spin-wave modes under microwave
pumping when a ferrimagnet is placed in a microwave waveguide that does not support any …

In the emerging field of cavity optomagnonics, photons are coupled coherently to magnons
in solid-state systems. These new systems are promising for implementing hybrid quantum …

Exotic quantum vacuum phenomena are predicted in cavity quantum electrodynamics
systems with ultrastrong light-matter interactions. Their ground states are predicted to be …

We demonstrate microwave-mediated distant magnon-magnon coupling on a
superconducting circuit platform, incorporating chip-mounted single-crystal Y 3 Fe 5 O 12 …

We show how to create quantum squeezed states of magnons and phonons in a cavity
magnomechanical system. The magnons are embodied by a collective motion of a large …
