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…

Twofold mechanical squeezing in a cavity optomechanical system

We investigate the dynamics of an optomechanical system where a cavity with a movable mirror involves a degenerate optical parametric amplifier and is driven by a periodically modulated laser field.

Enhancing quantum effects via periodic modulations in optomechanical systems

Parametrically modulated optomechanical systems have been recently proposed as a simple and efficient setting for the quantum control of a micromechanical oscillator: relevant possibilities include

Rapid mechanical squeezing with pulsed optomechanics

Macroscopic mechanical oscillators can be prepared in quantum states and coherently manipulated using the optomechanical interaction. This has recently been used to prepare squeezed mechanical

Opto- and electro-mechanical entanglement improved by modulation

One of the main milestones in the study of opto- and electro-mechanical systems is to certify entanglement between a mechanical resonator and an optical or microwave mode of a cavity field. In this

Squeezing of the mirror motion via periodic modulations in a dissipative optomechanical system.

TLDR
Both the numerical and analytical results predict that the squeezed state of the mirror motion around its ground state is achievable and is robust against the thermal noise because of the strong cooling effect outside the resolved-sideband regime.

Mechanical squeezing in a dissipative optomechanical system with two driving tones

The squeezed state of a macroscopic mechanical oscillator can be exploited to enhance the sensitivity of precision measurements. Here, we theoretically demonstrate that the displacement squeezing of

Enhancement of quantum synchronization in optomechanical system by modulating the couplings

We study two coupled optomechanical systems interact mutually through an optical fiber and a phonon tunneling, which are controlled by two switches K1 and K2. Compared to the quantum synchronization

Dynamical and quantum effects of collective dissipation in optomechanical systems

Optomechanical devices have been cooled to ground-state and genuine quantum features, as well as long-predicted nonlinear phenomena, have been observed. When packing close enough more than one

Cooling and squeezing via quadratic optomechanical coupling

We explore the physics of optomechanical systems in which an optical cavity mode is coupled parametrically to the square of the position of a mechanical oscillator. We derive an effective master

Split-sideband spectroscopy in slowly modulated optomechanics

Optomechanical coupling between the motion of a mechanical oscillator and a cavity represents a new arena for experimental investigation of quantum effects on the mesoscopic and macroscopic scale.
