Journal ArticleDOI
Bistability of Cavity Magnon Polaritons.
TL;DR: In this paper, 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 iron garnet (YIG) sphere was reported.
Journal ArticleDOI
Observation of the exceptional point in cavity magnon-polaritons
TL;DR: By tuning the magnon–photon coupling strength, an exceptional point and spontaneous symmetry breaking in a cavity magnon-polariton system are observed and the polaritonic coherent perfect absorption is observed and demonstrated at the exceptional point.
Journal ArticleDOI
Cavity quantum electrodynamics with ferromagnetic magnons in a small yttrium-iron-garnet sphere
TL;DR: Li et al. as discussed by the authors reported an experimental study of cavity quantum electrodynamics with ferromagnetic magnons in a small yttrium-iron-garnet (YIG) sphere at both cryogenic and room temperatures.
Journal ArticleDOI

TL;DR: In this paper, the magnon Kerr effect in a cavity-magnon system where magnons in a small yttrium iron garnet (YIG) sphere are strongly but dispersively coupled to the photons in a three-dimensional cavity was demonstrated.
Journal ArticleDOI
Observation of the exceptional point in cavity magnon-polaritons.
TL;DR: Zhang et al. as mentioned in this paper designed a tunable cavity quantum electrodynamics system with a small ferromagnetic sphere in a microwave cavity and engineer the dissipations of photons and magnons to create cavity magnon-polaritons which have non-Hermitian spectral degeneracies.
