量子光学力学中的高阶相互作用:二次项分析

Higher-Order Interactions in Quantum Optomechanics: Analysis of Quadratic Terms

Sina Khorasani

摘要:

本文提出了一种研究量子光学力学中二次非线性相互作用的全算符分析方法。该方法是基于高阶算子的应用,使用一个六维基的二阶算子,构成一个完全封闭的分解。我们考虑了两种类型的标准位置场和最近预测的非标准动量场的二次相互作用,这是显着的机械频率与光学频率的比例是不可忽略的。这一未被探索的大机械频率区域可以在包括超导电动力学和模拟量子腔电动力学电路在内的少数平台上进行研究。结果表明,在适当的条件下,非标准二次相互作用的存在是可以观察到的。

英文摘要:

This article presents a full operator analytical method for studying the quadratic nonlinear interactions in quantum optomechanics. The method is based on the application of higher-order operators, using a six-dimensional basis of second order operators which constitute an exactly closed commutators. We consider both types of standard position-field and the recently predicted non-standard momentum-field quadratic interactions, which is significant when the ratio of mechanical frequency to optical frequency is not negligible. This unexplored regime of large mechanical frequency can be investigated in few platforms including the superconducting electromechanics and simulating quantum cavity electrodynamic circuits. It has been shown that the existence of non-standard quadratic interaction could be observable under appropriate conditions.
