Abstract
A technique to realize laser cooling of a nanomechanical resonator mode to its motional ground state by coupling to a laser driven quantum dot (QD) was proposed. A semiconductor beam structure which supports a high-Q mode of frequency ω was considered. By the difference between the electron-phonon couplings of the initial and final states of the quantum dot optical transition, the strength of the sideband coupling was determined. It was shown that the possible applications of this scheme include generation of nonclassical states of mechanical motion.
