Macroscopic entanglement between ferrimagnetic magnons and atoms via crossed optical cavity

Ke Di, Xi Wang, Huarong Xia +4

We consider a two-dimensional opto-magnomechanical (OMM) system including two optical cavity modes, a magnon mode, a phonon mode, and a collection of two-level atoms. In this study…
