Microwave single-tone optomechanics in the classical regime

We report on the quantitative experimental illustration of elementary optomechanics within classical regime. All measurements are performed in a commercial dilution refrigerator mesoscopic drumhead aluminium resonator strongly coupled to microwave cavity, using only strict single-tone schemes. Sideband asymmetry is reported in-cavity pumping, along with noise squashing and back-action effects. Results presented this paper analysed simple electric circuit theory, emphasizing analogous nature features respect their usual quantum description. The agreement theory obtained no fitting parameters. Besides, based those results method proposed for accurate measurement ratio between internal losses external coupling.
