… ferromagnet and discuss its magnon band structure and topology. In Sec. III, we study the
magnon band structures of the Weyl ferromagnet … We also study the magnon dynamics due to …

… magnon modes and their frequencies. The measurements are extended to the quantum
limit … Cavity quantum electrodynamics with ferromagnetic magnons in a small yttrium-iron-garnet …

… As magnons propagate across the … emitted magnons, and we show that the magnon emission
is a Poissonian process. Finally, we probe the emission energy threshold of the magnons …

… An empty ket and a double arrow denote a fully saturated ferromagnet and a spin-ℏ magnon,
respectively, which become the ground state and eigenexcitation in the isotropic case (right…
