Xin Zhou, Dylan Cattiaux, Didier Theron, Eddy Collin

摘要:

我们报告的通用经典电路建模,描述了标准的单音微波光学力学。基于一个并联RLC电路中的机械振荡器作为一个可移动的电容器,推导的解析表达式,包括关键功能,如反作用力,输入输出表达式,和相关的频谱密度,所有在经典的制度。当腔和机械振子的占有数都很大时,这些表达式与光力学中的标准量子处理相一致。此外,衍生的分析将光学元件和特性转换为电子术语,这对于定量测量和设计目的是强制性的。最后,标准量子处理和经典模型之间的直接比较解决了量子和经典制度之间的界限,突出了真正量子的特征,以及那些不是。

英文摘要:

We report on the generic classical electric circuit modeling that describes standard single-tone microwave optomechanics. Based on a parallel RLC circuit in which a mechanical oscillator acts as a movable capacitor, derivations of analytical expressions are presented, including key features such as the back-action force, the input-output expressions, and the spectral densities associated, all in the classical regime. These expressions coincide with the standard quantum treatment performed in optomechanics when the occupation number of both cavity and mechanical oscillator are large. Besides, the derived analytics transposes optical elements and properties into electronics terms, which is mandatory for quantitative measurement and design purposes. Finally, the direct comparison between the standard quantum treatment and the classical model addresses the bounds between quantum and classical regimes, highlighting the features which are truly quantum, and those which are not.
