摘　　要：Ground state cooling of massive mechanical objects remains a difficult task restricted by the unresolved mechanical sidebands. We propose an optomechanically-induced-transparency cooling scheme to achieve ground state cooling of mechanical motion without the resolved sideband condition in a pure optomechanical system with two mechanical modes coupled to the same optical cavity mode. We show that ground state cooling is achievable for sideband resolution ωm/k as low as - 0.003. This provides a new route for quantum manipulation of massive macroscopic devices and high-precision measurements.Ground state cooling of massive mechanical objects remains a difficult task restricted by the unresolved mechanical sidebands.
