Abstract
We analytically investigate a theoretical scheme to enhance the bi-partite entanglement of directly and indirectly coupled modes in a magnomechanical system which is composed of two microwaves (MW) cavity mode photons, magnons and phonons. The magnon mode not only simultaneously couples with two MV cavity modes, via the magnetic dipole interaction, but also with mechanical mode via magnetostrictive interaction. The two MW fields can be entangled if they are, respectively, resonant with two sidebands of the mechanical mode. Interestingly, the numerical simulation results show that the magnon interaction with two MV cavity modes leads to an enhanced entanglement spectrum of directly (magnon–phonon) and indirectly (cavity–phonon) coupled modes. We also show that the entanglement of directly and indirectly coupled modes persists for temperature up to 250 mK which is higher than the previously observed value.
