Quantum Theory of Radiation Pressure Cooling
A central question which has arised recently in the field of optomechanical cooling is if back-action cooling can be used to cool a mechanical oscillator to the ground state. We have successfully addressed this question and formulated a quantum theory of radiation pressure self cooling - jointly with the W. Zwerger group - , showing that ground state cooling is only possible, provided the mechanical frequency is larger than the cavity linewidth - analogous to resolved sideband cooling of ions -
