… Further, we show that increasing the nonlinear gain coefficient … coupling rate of each microwave
cavity mode and magnon … coupling rate between each cavity mode and magnon mode is …

… III B, we analyze the nonlinear effect of quadratic coupling in the absorption spectra of the
magnon mode. We discuss all the numerical results based on the formulas derived in Sec. II. …

… We consider two optical modes and the uniform magnon mode, as was assumed for the …
Such signal is a consequence of two-photon transitions driven by the nonlinear coupling term in …

… Here we will use the latter one because it is simpler for introducing the magnon nonlinear …
because sufficient driving is supplied to mode 2 via the nonlinear coupling with mode 1. …

… modes, magnons, can be coherently coupled to microwave photons in the single excitation
limit. This allows for access to quantum properties of magnons … intrinsic magnon nonlinearity …

… be incorporated into hybrid systems with a nonlinear element such as a Josephson junction.
… mode and two magnon modes, where the photon-magnon and magnonmagnon couplings …

… a magnon edge mode to a parametric instability, which, when taking into account nonlinear
… γ increases the anomalous coupling for modes with wavevector close to π and that the …

… In the last case, magnons and phonons are coupled via nonlinear magnetostrictive
interaction, which is of radiation pressure type, and therefore many known results in the well-…

… In the latter system, the nonlinearity of Josephson junctions plays … magnon coupling, we
perform qubit excitation spectroscopy by using the qubit readout through the cavity TE 103 mode…

… We identify two mode-coupling mechanisms: (i) magnon… the dominant modes and a bath of
thermally excited magnons; … exchange coupling between the dominant, finitevolume modes. …
