In this paper, we present some properties through two two-level atoms interacting with a two-mode quantized cavity field. We study this system in the presence of detuning parameter, Kerr nonlinearity, Stark shift, relative phase and intensity-dependent atoms-field coupling. Also, the coupling parameter is modulated to be time dependent. The exact solution of this model is given by using the Schrődinger equation when the atoms and the field are initially prepared in superposition states and coherent states, respectively. We employed the results to calculate some aspects such as linear entropy, total atomic inversion and cross-correlation function.

双模腔中非线性时间相关的两个两能级原子的动力学

在本文中,我们通过两个两能级原子与双模量子化腔场相互作用来展示一些性质。我们在存在失谐参数、克尔非线性、斯塔克位移、相对相位和强度相关的原子场耦合的情况下研究该系统。此外,耦合参数被调制为时间相关的。当原子和场最初分别准备在叠加态和相干态时,使用薛定谔方程给出了该模型的精确解。我们利用结果来计算线性熵、总原子反演和互相关函数等方面。
