- Abstract summary: Magnonic frequency combs have recently attracted particular attention due to their potential impact on spin-wave science.
Here, we demonstrate theoretically the generation of ultra-wideband (UWB) magnonic frequency combs induced by dissipative coupling in an open cavity magnomechanical system.
A broadband comb with gigahertz repetition rates is obtained in the magnonic spectrum and a typical non-perturbation frequency-comb structure is also observed.

- Abstract: Magnonic frequency combs have recently attracted particular attention due to
their potential impact on spin-wave science. Here, we demonstrate theoretically
the generation of ultra-wideband (UWB) magnonic frequency combs induced by
dissipative coupling in an open cavity magnomechanical system. A broadband comb
with gigahertz repetition rates is obtained in the magnonic spectrum and a
typical non-perturbation frequency-comb structure is also observed. The total
width of the magnonic comb in the robust plateau region can be up to 400 comb
lines, which is much broader and flatter than the reported in the previous
works. Furthermore, when the dissipative coupling strength is further
increased, the chaotic motion is predicted in the magnonic spectrum. Our
results provide an in-depth understanding of nonlinear magnomechanic dynamics
in open quantum systems and fundamentally broadens the research range of magnon
in new spectral regimes.
