Ground state cooling of micromechanical oscillators in the unresolved sideband regime induced by a quantum well

Abstract

Ground state cooling of micromechanical oscillator is a paradigmatic goal for observing quantum mechanical effects in cavity optomechanics. We study theoretically the ground state cooling of a mechanical oscillator in an optomechanical cavity in presence of a quantum well placed inside the cavity. Due to mode tailoring in presence of the quantum well, the cavity response gets modified and leads to asymmetric heating and cooling processes. This facilitates the cooling of the mechanical oscillator even in the unresolved-sideband regime, via inhibition of Stokes scattering.
