Outline

Recently, experiments using high-Q massive mechanical oscillators have been proposed for testing quantum mechanics and probing Planck scale physics.
The basic requirements for these experiments is reduction of the thermal decoherence rate, i.e. the inverse time of the absorption of a phonon from the environment, under the mechanical resonance.
In this project, I aim to cool the mg-scale suspended mirror down to its motional ground state, and keep the state over one mechanical period by reducing the thermal decoherence rate.
