Optomechanics with molecules and solid-state mechanical resonators

Optical photons typically carry very little energy and momentum. Despite this, they can still be successfully employed to control the motion of various objects ranging from small molecules to macroscopic vibrating mirrors or membranes. We theoretically employ stochastic methods to show how light can be used to read out vibrations of nuclei in molecules [1] or to cool down the motion of photonic crystal mirrors [2] or membranes [3], close to their quantum ground state.
