We show how to enhance the detection sensitivity of magnon Kerr nonlinearity (MKN) in
cavity magnonics. The considered cavity-magnon system consists of a three-dimensional …

We propose to realize the pseudo-Hermiticity in a cavity magnonics system consisting of the
Kittel modes in two small yttrium iron garnet spheres coupled to a microwave cavity mode …

We develop a theory for the magnon Kerr effect in a cavity magnonics system, consisting of
magnons in a small yttrium iron garnet (YIG) sphere strongly coupled to cavity photons, and …

We propose a scheme to achieve the nonreciprocal amplification in a hybrid cavity
magnonics system. Because of the destructive interference between different paths and the …

Magnon Kerr nonlinearity plays a crucial role in the study of an optomagnonical system and
may bring many interesting physical phenomena and important applications. In this Letter …

In non-Hermitian systems, the eigenfrequency of resonance modes coalesces at the
exceptional points (EPs) in the frequency domain, leading to extraordinary parametric …

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 …

Inspired by the new discovery that the nonlinear dynamics of the cavity magnon polaritons
have been observed with a small yttrium iron garnet (YIG) sphere (which introduces a …

We propose an alternative scheme to achieve the cross-correlations between magnon and
photon in a hybrid nonlinear system including two microwave cavities and one yttrium iron …

Magnon–polaritons are hybrid light–matter quasiparticles originating from the strong
coupling between magnons and photons. They have emerged as a potential candidate for …
