The coupling phase in cavity magnonics

Résumé

- Cavity magnonics relevant for quantum transducers, quantum memories (using dark mode physics), non-reciprocal devices: such applications justify studying cavity magnonics in multimode systems. - Microwave photon/magnon coupling due to Zeeman coupling involves a coupling phase factor which is usually rightfully neglected. ⇒ unless the system is "loop-coupled" (see next section for definition and examples), coupling phases are unobservables. - (Experimentally) Simplest system in which the coupling phases manifest: two magnon modes coupling simultaneously to two cavity modes. The various coupling phases accumulate in a single quantity θ: the physical phase. Physical phase found to influence the presence of dark modes, and the strength of the cavity-mediated coupling.
