Query: Cavity mediated level attraction and repulsion between magnons   We characterize some of the distinctive hallmarks of magnon-magnon
interaction mediated by the intracavity field of a microwave cavity, along with
their testable ramifications. In general, we foreground two widely dissimilar
parameter domains that bring forth the contrasting possibilities of level
splitting and level crossing. The former is observed in the regime of strong
magnon-photon couplings, particularly when the three modes bear comparable
relaxation rates. This character is marked by the appearance of three
distinguishable and non-converging polariton branches in the spectral response
to a cavity drive. However, when the bare modes are resonant and the couplings
perfectly symmetrical, one of the spectral peaks gets wiped out. This anomalous
extinction of polaritonic response can be traced down to the existence of a
conspicuous dark mode alongside two frequency-shifted bright modes. In an
alternate parameter regime, where the magnon modes are weakly coupled to the
cavity, features of level attraction unfold, subject to a large relaxation rate
for the cavity mode. Concurrently, for antisymmetric detunings to the magnon
modes, a transmission window springs into existence, exhibiting transparency in
the limit of negligible dissipation from the magnons. The emergence of level
attraction can be reconciled with a theoretical model that embodies the
dynamics of the magnon-magnon subsystem when the cavity field decays rapidly
into its steady state. In this limit, we identify a purely dissipative coupling
between the magnon modes.
