Findings

Both mirror and field can be modeled as squeezed thermal states.

Proper parameter tuning enables control over their dynamical properties.

Conditional procedures can amplify correlation properties.

Abstract

We characterize the local properties of an optomechanical system comprising the movable mirror of a resonator and its intracavity field, mutually coupled via radiation-pressure. Our approach shows that both the state of the mirror and the field can be interpreted as squeezed thermal states whose dynamical properties can be tuned by properly choosing the working parameters. This allows us to design conditional procedures for the amplification of the correlation properties of the optomechanical state. Our study is a step forward in the understanding of the physics that rules a system of current enormous experimental interest.
