Ground-state cooling of a mechanical resonator in a hybrid magnon squeezing magnomechanical system
Abstract:
Cavity magnomechanics has emerged as a new platform for the study of macroscopic quantum phenomena. A hybrid magnon squeezing magnomechanical system is proposed to realize the ground-state cooling of the magnomechanical resonator in the unresolved sideband regime, which consists of a magnon mode, two microwave cavity modes, and a mechanical vibration mode. We demonstrate that magnomechanical Stokes scattering can be completely suppressed by magnon squeezing under appropriate conditions, which greatly enhances the cooling performance of the magnomechanical resonator. Additionally, the cooling process can be further promoted by coupling with two microwave cavities. This scheme provides what we believe to be a novel idea for the subsequent ground-state cooling research and makes it possible to realize quantum manipulation of macroscopic mechanical systems.
