    "abstract": "We demonstrate passive feedback cooling of a mechanical resonator based on\nradiation pressure forces and assisted by photothermal forces in a high-finesse\noptical cavity. The resonator is a free-standing high-reflectance micro-mirror\n(of mass m=400ng and mechanical quality factor Q=10^4) that is used as\nback-mirror in a detuned Fabry-Perot cavity of optical finesse F=500. We\nobserve an increased damping in the dynamics of the mechanical oscillator by a\nfactor of 30 and a corresponding cooling of the oscillator modes below 10 K\nstarting from room temperature. This effect is an important ingredient for\nrecently proposed schemes to prepare quantum entanglement of macroscopic\nmechanical oscillators.",
