论文摘要
我们考虑了在初始基态下以挤压参数r的任意值在初始挤压的相干状态下与野外模式相互作用的两级原子在初始基态中的抗jaynes-cummings(AJC)相互作用,并提供了Jaynes-Cummings(JC)相互作用作为比较。我们分析了通过von Neumann熵测量的纠缠程度(DEM),以及由Mandel Q参数量化的磁场性质与AJC相互作用期间的原子群反转和相应的JC相互作用相关。我们在示例中指出,在r> 1.4时,光子统计量在各自的AJC JC相互作用期间从亚poissonian中演变为超级波多桑尼亚人。此外,对于高度的R值,与初始相干状态相比,原子种群反演的时间演变的形式描述了塌陷区域的响起复兴。更重要的是,在R的较高值中,DEM的时间演变显示出更快的振荡,并记录了更高的值,同时增加了混合度的增加。
We considered the anti-Jaynes-Cummings (AJC) interaction of a two-level atom in an initial ground state interacting with a field mode in an initial squeezed coherent state at arbitrary values of squeeze parameter r and provided the Jaynes-Cummings (JC) interaction as a comparison. We analysed the degree of entanglement (DEM) measured by the von Neumann entropy and the nature of the field quantified by the Mandel Q parameter in relation to the atomic population inversion during the AJC interaction and separately the corresponding JC interaction. We noted in our examples that at r>1.4, photon statistics evolved to super-Poissonian from sub-Poissonian during the respective AJC, JC interactions. Further, for high values of r, the form of the time evolution of atomic population inversion depicted enhanced ringing revivals at the collapse region in comparison to the case of an initial coherent state. What is more, at higher values of r the time evolution of DEM showed more rapid oscillations and recorded higher values, concurrently, an increase in the degree of mixedness.
