论文摘要
我们引入了一个动力学系统，该系统并没有像通常的Jaynes-Cummings模型（JCM）那样交换单个光子，而是交换了一个挤压相干光子。因此，JCM中的创建和歼灭光子操作员分别被挤压相干状态的创建和an灭操作员取代。这种转换产生了一种光子哈密顿量，该光子在进行旋转波近似时通常省略了JCM的JCM，此外，转换引入了JCM中不存在原子交换项。
We introduce a dynamical system that instead of exchanging a single photon as in the atomic system of the usual Jaynes-Cummings model (JCM), it exchanges instead a squeezed coherent photon. Accordingly, the creation and annihilation photon operators in the JCM are replaced by the creation and annihilation operators of squeezed coherent states, respectively. This transformation generates a photon Hamiltonian that modifies the JCM that includes terms usually omitted in the JCM when making the rotating-wave approximation and, in addition, the transformation introduces atom exchange terms absent in the JCM.
