  We theoretically study the radiation-induced interaction between the
mechanical motion of an oscillating mirror and a remotely trapped atomic cloud.
When illuminated by continuous-wave radiation, the mirror motion will induce
red and blue sideband radiation, which respectively increases and reduces
motional excitation. We find that by suitably driving $\Lambda$-level atoms,
the mirror correlation with a specific radiation sideband could be converted
from the outgoing to the incoming radiation. Such process allows us to
manipulate the heating and cooling effects. Particularly, we develop an
optomechanical cooling strategy that can mutually cancel the heating effect of
the outgoing and incoming radiations, thus the motional ground state is
attainable by net cooling. Without the necessity of cavity installation or
perfect alignment, our proposal complements other efforts in quantum cooling of
macroscopic objects.
