In this work, spin-wave magnon-polaritons are studied by using a split-ring resonator loaded
with a spherical single-crystal bulk yttrium–iron–garnet chip. The coherent magnon–photon …

Hybrid quantum systems based on magnetic platforms have witnessed the birth and fast
development of quantum magnonics. Until now, most studies have relied on magnetic …

A photon-magnon hybrid system can be realized by coupling the electron spin resonance of
a magnetic material to a microwave cavity mode. The quasiparticles associated with the …

Nonclassical quantum states are the pivotal features of a quantum system that differs from its
classical counterpart. However, the generation and coherent control of quantum states in a …

We study the dynamics of a spin ensemble strongly coupled to a single-mode resonator
driven by external pulses. When the mean frequency of the spin ensemble is in resonance …

Metamaterial resonant structures made from arrays of superconducting lumped-circuit
elements can exhibit microwave-mode spectra with left-handed dispersion for the standing …

Electrostatic gating confines and controls the transport of electrons in integrated circuits.
Magnons, the quanta of spin waves of the magnetic order, are promising alternative …

We demonstrate a planar superconducting microwave resonator intended for use in
applications requiring strong magnetic fields and high quality factors. In perpendicular …

Controlling magnon densities in magnetic materials enables driving spin transport in
magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon …

Strong coupling between magnons and cavity photons was studied extensively for quantum
electrodynamics in the past few years. Recently, the strong magnon–magnon coupling …
