微波腔实验中原子探测的动力学模型

Atomic detection in microwave cavity experiments: a dynamical model

R. Rossi, M. C. Nemes, J. G. Peixoto de Faria

摘要:

利用腔量子电动力学(QED)研究了电磁模叠加的相干性,建立了一个探测单原子脉泽的模型。考虑到由于电离场与原子相互作用的概率性质而导致测量过程的不完善性,得到了原子电离的解析表达式。有限的效率和假计数率被认为是在一个动态的上下文中,由此得到的结果的信息的腔模式的状态。

英文摘要:

We construct a model for the detection of one atom maser in the context of cavity Quantum Electrodynamics (QED) used to study coherence properties of superpositions of electromagnetic modes. Analytic expressions for the atomic ionization are obtained, considering the imperfections of the measurement process due to the probabilistic nature of the interactions between the ionization field and the atoms. Limited efficiency and false counting rates are considered in a dynamical context, and consequent results on the information about the state of the cavity modes are obtained.
