Squeezing optomechanical systems — •Andrea Mari1 and Jens Eisert1,2 — 1Institute of Physics and Astronomy, University of Potsdam, D-14476 Potsdam, Germany — 2Institute for Advanced Study Berlin, D-14193 Berlin, Germany
We introduce a framework of optomechanical systems that are driven with a mildly amplitude-modulated light field, but that are not subject to classical feedback or squeezed input light. We find that in such a system one can achieve large degrees of squeezing of a mechanical micromirror - signifying quantum properties of optomechanical systems - without the need of any feedback and control, and within parameters reasonable in experimental settings. Entanglement dynamics is shown of states following classical quasiperiodic orbits in their first moments. We discuss the complex time dependence of the modes of a cavity-light field and a mechanical mode in phase space. Such settings give rise to certifiable quantum properties within experimental conditions feasible with present technology.
